About This Product

The Floor Mounted Scissor Lift is a fixed hydraulic lifting platform for vertically positioning pallets, components, dies, fixtures, and other industrial loads. It is installed on a level factory or warehouse floor and anchored in a defined operating location, providing a stable interface between loading points, workstations, conveyors, machines, or storage areas. Its surface-mounted arrangement avoids the civil work associated with pit excavation while retaining the stability required for repetitive material handling.

The lift is intended for industrial load handling rather than personnel transportation. It is particularly relevant where material must be raised or lowered repeatedly at one workstation, where mobile equipment would interrupt the process, or where operators require a more ergonomic load presentation height.

Hydraulic Lifting Principle

A hydraulic power pack supplies pressurized fluid to cylinders connected to the scissor arm assembly. As the cylinders extend, the scissor linkage opens and raises the platform in a controlled vertical path; reversing the hydraulic flow allows the linkage to contract and lower the load. This operating principle supports smooth movement and accurate load positioning within the designed travel range.

The available lifting speed ranges from 0.05 to 0.15 m/s, depending on the engineered configuration. Travel limit switches control the upper and lower operating range, while the hydraulic hose burst valve helps prevent uncontrolled descent if a hose fails.

Fixed Workflow Integration

Because the unit is surface anchored, it is suited to repeatable workflows in which the loading and discharge positions remain consistent. Typical installations support machine loading, pallet positioning, assembly work, die and mould handling, conveyor height matching, packaging line feeding, and warehouse load transfer. A stable base frame and rigid platform help maintain predictable alignment with adjoining equipment.

Controls may be configured for independent operation or coordinated with a wider production system. Depending on project requirements, integration can include PLC, HMI, foot-switch, remote, wireless, conveyor, or production-line control arrangements.

Industrial Operating Range

Configured capacities extend from 500 kg to 5,000 kg, with platform sizes from 1000x1000 mm to 2000x3000 mm. Lift travel can range from 500 mm to 3,000 mm, while the collapsed height generally ranges from 200 mm to 600 mm. The appropriate combination is selected from the load footprint, weight distribution, required elevation, operating frequency, and available installation space.

The Floor Mounted Scissor Lift is designed primarily for indoor industrial environments with a stable, level floor and controlled exposure to dust, water, and corrosive substances. Special finishes may be considered where environmental or hygiene conditions differ from a conventional manufacturing setting.

Applications

Machine Loading Operations

At machining and production stations, the lift can raise components, fixtures, or tooling to the working height of the machine interface. This reduces repeated manual lifting and can limit dependence on cranes or forklifts for routine vertical positioning. The fixed location also supports consistent alignment during loading and unloading.

Platform dimensions and capacity should account for the complete load, including fixtures, pallets, and any concentrated contact points. Where machine cycles require coordinated movement, the lift controls may be integrated with the surrounding production system.

Pallet Positioning Workflows

Palletized materials can be raised to a practical transfer or picking height in receiving, staging, dispatch, and production areas. Operators can work with the load at a more accessible elevation instead of repeatedly bending or lifting from floor level. The compact collapsed profile supports easier initial loading, although the selected height must still suit the loading method.

The platform is configured around pallet dimensions, orientation, and weight distribution. Chequered plate, mild steel, or stainless steel surfaces can be selected according to grip, environment, and material handling requirements.

Assembly Work Positioning

In assembly operations, the platform can present work-in-progress, subassemblies, or fixtures at a controlled height. This helps technicians access the load from a more ergonomic working position and supports repeatable movement between assembly stages. It is useful where the component remains on a pallet or fixture during processing.

Foot-switch, remote, or HMI control may be incorporated when operators need to adjust the height while keeping their hands available for assembly tasks. Guarding and control placement must be engineered around operator access and the specific workstation layout.

Conveyor Height Matching

A Floor Mounted Scissor Lift can serve as an adjustable transfer point between conveyors, machines, packaging equipment, or material staging positions at different elevations. The platform raises or lowers a load to the required interface height before transfer. This arrangement can reduce awkward intermediate handling and support a more continuous material path.

Conveyor integration requires evaluation of transfer direction, platform loading, controls, sensing, and stopping accuracy. The lift may be configured with coordinated PLC or production-line controls, subject to application engineering.

Die And Mould Handling

Dies, moulds, and production tooling often require controlled positioning because of their weight and concentrated load pattern. A fixed scissor lift can elevate these loads between storage, staging, maintenance, and machine loading heights. The rigid platform and surface-anchored base support stable positioning at a dedicated handling point.

Engineering review is particularly important for loads with small support areas, offset centres of gravity, or uneven weight distribution. Capacity selection must consider the actual load pattern rather than only the total stated weight.

Packaging Line Feeding

Packaging operations can use the lift to position cartons, crates, packaging materials, or wrapped loads at the entry or discharge height of a line. It can also support ergonomic replenishment at packing stations and controlled transfer of finished packages to pallet handling areas. Repeatable elevation helps coordinate manual and automated process steps.

Platform finish and controls can be adapted to the environment and operating sequence. Stainless steel, food-grade, cleanroom, galvanized, weatherproof, or custom-painted finishes may be considered where supported by the application specification.

Warehouse Load Transfer

In warehouses and logistics facilities, the lift can elevate pallets, crates, containers, and loading carts between defined floor or storage transfer heights. Typical uses include receiving-area elevation, dispatch pallet positioning, order preparation, and movement to mezzanine-related transfer points. The equipment remains fixed, making it most suitable where the vertical transfer route is permanent.

Applications involving multiple separate landing levels or complex access arrangements require engineering consultation. Safe loading clearances, edge protection, barriers, and controls must correspond to each transfer interface.

Production Material Staging

Raw materials, work-in-progress, and finished goods can be staged at a height that matches the next manufacturing process. This supports orderly flow between fabrication, machining, assembly, inspection, and packaging without unnecessary intermediate lifting. Fixed positioning also helps define a repeatable handover point between departments or material handling devices.

The selected platform size should accommodate both the load and the loading equipment used to place it. Forklift, pallet truck, cart, or conveyor interfaces must be reviewed so that loads enter and leave the platform safely.

Benefits

Improved Operator Ergonomics

Controlled vertical positioning brings pallets, parts, and fixtures closer to a suitable working or transfer height. This reduces unnecessary bending, reaching, and repetitive manual lifting during assembly, packing, picking, and machine loading. The benefit is created by changing the load elevation rather than requiring workers to adapt continually to a fixed floor-level load.

Repeatable Material Flow

A fixed, anchored installation establishes a consistent vertical handling point within the process layout. Loads can be positioned repeatedly between known heights, supporting coordinated transfer to machines, conveyors, workstations, and staging areas. Travel limit switches and configurable controls help maintain the operating sequence required by the application.

This repeatability can reduce delays caused by ad hoc staging or dependence on shared lifting equipment. It also supports more predictable production and warehouse workflows without implying a fixed throughput improvement for every installation.

Reduced Civil Work

The surface-mounted design avoids the need to excavate a pit for the lift structure. This can simplify installation planning where floor alteration is undesirable or where existing facility conditions make pit construction impractical. The trade-off is a collapsed platform height above floor level, which must be considered when planning load access and trip protection.

Protected Load Handling

Smooth hydraulic movement and a rigid load platform support controlled elevation of pallets, components, dies, and packaged goods. Reducing abrupt or improvised manual transfers can help limit handling-related product damage. Correct platform sizing and load distribution remain essential because the lift is designed to operate within defined structural and stability limits.

Application Configuration Flexibility

Capacity, platform dimensions, lift travel, scissor geometry, power supply, platform surface, and control arrangements can be selected around the operating requirement. Single, double, triple, or tandem scissor layouts allow the lifting geometry to be matched to travel and platform needs. This flexibility enables the equipment to serve a dedicated process rather than forcing the process around a generic lift table.

Project-specific options can also support conveyor integration, automation, environmental finishes, and alternative operator controls. Each variation remains subject to engineering evaluation of load, space, duty, and safety conditions.

Technical Highlights

Fabricated Scissor Structure

The load is supported by a heavy-duty fabricated steel scissor arm assembly mounted between the platform and stable base frame. Scissor movement converts hydraulic cylinder force into vertical platform travel while maintaining the intended load path. The structure can be arranged as single, double, triple, or tandem geometry according to travel, platform length, and stability requirements.

Structural selection must consider total load and distribution across the platform. Concentrated, offset, or changing loads require specific review because nominal capacity alone does not define the stresses applied to the scissor structure.

Capacity And Travel Range

Available rated capacities range from 500 kg to 5,000 kg, with lift travel from 500 mm to 3,000 mm. Platform dimensions range from 1000x1000 mm to 2000x3000 mm, allowing configuration around pallets, fixtures, components, and industrial containers. Requirements outside these ranges, or applications with unconventional load geometry, should be referred for project-specific engineering.

Collapsed heights range from 200 mm to 600 mm. Selection should balance required travel and structural geometry against convenient loading access and the available vertical clearance.

Hydraulic Power System

The low-maintenance hydraulic operating system includes a power pack, hydraulic cylinders, hoses, and flow-control components. Motor ratings range from 2.2 kW to 7.5 kW, depending on the lift configuration and operating demand. Available supplies include 230V single-phase, 415V three-phase, or battery DC power.

Power pack positioning should provide suitable hose routing, ventilation, service access, and protection from impact or contamination. Hydraulic configuration is selected according to site utilities, operating frequency, load, speed, and installation layout.

Platform Load Interface

The rigid platform provides the direct interface with the handled load and is available in chequered plate, mild steel, or stainless steel. Platform length and width can be configured around the load footprint, transfer direction, loading equipment, and adjoining machinery. Surface selection influences grip, cleanability, corrosion resistance, and suitability for the operating environment.

Additional construction finishes may include galvanized, weatherproof, food-grade, cleanroom, or custom-painted arrangements. These should be specified as project requirements rather than assumed to be part of every lift.

Controls And Automation

The control system governs lifting, lowering, stopping, and travel limits. Depending on the application, the lift can be configured with a control panel, PLC, HMI, remote control, foot-switch, wireless control, or signals coordinated with conveyors and production equipment. Control selection should reflect operator position, visibility, cycle sequence, and the required level of automation.

Manual override functions may be incorporated as part of the control arrangement. Any interface with external machinery requires a defined control philosophy so that material transfer and lift movement occur in the intended safe sequence.

Integrated Safety Functions

Supported safety provisions include emergency stop, overload protection, hydraulic hose burst valve, travel limit switches, photoelectric safety sensors, safety railings, and safety gates. These devices address different hazards, including excess loading, unexpected descent, travel beyond the intended range, obstruction, and platform-edge exposure. The final safety arrangement depends on how the platform is loaded, accessed, and integrated into the site.

Safety devices do not replace correct operating procedures or guarding design. Their locations and control relationships should be validated during installation and commissioning.

Industries Served

Automotive Production

Automotive facilities can use the lift for body panels, engine components, subassemblies, fixtures, tooling, and production materials. It can position these loads at assembly stations, support movement between production stages, or align material with adjoining handling equipment. Fixed vertical positioning is especially useful where the same component route is repeated across production cycles.

Platform dimensions and load distribution should be engineered around the fixture or component rather than only its nominal weight. Production-line controls may be incorporated when lift movement must coordinate with station sequencing.

Engineering And Metalworking

Engineering and metalworking operations handle machined parts, fabricated assemblies, tools, dies, moulds, and work-in-progress that may be dense or irregularly shaped. A Floor Mounted Scissor Lift can raise these loads for machining, inspection, assembly, maintenance, or transfer. This reduces improvised lifting and establishes a controlled staging point near the process.

Concentrated contact areas and offset centres of gravity are common in this sector, making application review important. Heavy-duty structural configuration, suitable platform dimensions, and the correct scissor geometry should be selected for the actual load pattern.

Manufacturing Operations

General manufacturing plants can apply the lift across raw material transfer, component positioning, work-in-progress elevation, finished goods handling, and packaging-line supply. The equipment can bridge different process heights while remaining in a dedicated location within the production layout. This supports organized handover between manual operations, material handling equipment, and automated stations.

Control and surface options allow configuration around the process environment. The lift may operate as a stand-alone workstation or as an integrated element in a conveyor-fed manufacturing line.

Warehousing And Logistics

Warehouses and logistics centres can use the platform for shipping pallets, crates, packaged goods, loading containers, and staging materials. Relevant workflows include receiving-area elevation, order preparation, dispatch positioning, floor-level transfer, and movement toward defined storage or mezzanine interfaces. The fixed installation is appropriate where the transfer location remains constant.

Traffic flow must be planned carefully because forklifts, pallet trucks, and pedestrians may share the surrounding area. Barriers, approach clearances, control visibility, and platform alignment should be designed around the site's loading method.

Packaging And FMCG

Packaging and FMCG operations can elevate cartons, plastic crates, wrapped loads, consumer goods, and packaging supplies between production and packing stages. At a packing station, the lift can present materials at a practical working height; at a line interface, it can match transfer elevations. Repeatable positioning supports continuity when products move through several handling and packaging steps.

Platform finish should correspond to cleaning, grip, and environmental needs. Food-grade, stainless steel, cleanroom, or other special finishes may be configured where the application specification supports them.

Pharmaceutical Material Handling

Pharmaceutical operations can use the lift for packaged products, secondary packaging materials, cartons, plastic containers, and finished goods packages. Typical roles include packaging support, controlled load elevation, and transfer between defined process or storage positions. The lift assists organized material movement without redefining the site's hygiene or process-control procedures.

Stainless steel, cleanroom, or application-specific finishes may be considered according to environmental requirements. Selection should address cleaning access, contamination control, platform material, guarding, and integration with surrounding packaging equipment.

Industrial Automation Systems

Automated production environments can incorporate the lift as a vertical positioning module between conveyors, cells, or processing stations. PLC, HMI, sensor, remote, and production-line interfaces may be configured to coordinate platform movement with load arrival and discharge. The fixed base provides a repeatable physical reference for these transfers.

Automation projects require a defined sequence for sensing, interlocking, stopping, emergency control, and recovery from faults. Highly customized control requirements should be reviewed during engineering rather than added after installation.

Why Choose NIO Equipment

Application Specific Engineering

Nio Equipment approaches the Floor Mounted Scissor Lift as an installation-specific material handling system rather than a stand-alone catalogue component. Selection can account for load weight, footprint, distribution, travel, collapsed height, transfer direction, operating frequency, and surrounding equipment. This is particularly important for dies, fixtures, long platforms, concentrated loads, and integrated production workflows.

Applications beyond 5,000 kg, above 3,000 mm travel, or outside the listed platform range require dedicated consultation. Structural floor constraints, uneven loading, and multiple landing positions are also identified early so that feasibility can be evaluated before manufacture.

Configurable Product Architecture

Nio Equipment can configure capacity, platform dimensions, scissor geometry, hydraulic power pack, platform material, construction finish, and control arrangement around the project. Single, double, triple, or tandem scissor configurations can be considered according to travel and stability requirements. Available power arrangements include 230V single-phase, 415V three-phase, and battery DC.

Optional PLC, HMI, foot-switch, remote, wireless, conveyor, and production-line controls support different levels of operator interaction and automation. These options are selected according to the application and are not assumed to be standard on every unit.

Manufacturing And Integration Capability

Nio Equipment combines custom equipment design and manufacturing with an understanding of hydraulic lifting and industrial material flow. This supports coordination between the fabricated structure, hydraulic system, controls, platform interface, and site installation requirements. The result can be developed around a defined machine, conveyor, workstation, or warehouse transfer point.

Integration planning can address physical alignment as well as control sequencing. This is valuable where the lift must operate as part of a larger automated or semi-automated process.

Installation Focused Support

Support from Nio Equipment can extend to installation planning, commissioning, and application-based site coordination in India. Floor condition, mounting anchors, power pack placement, electrical supply, loading access, guarding space, and maintenance clearance can be reviewed as part of project preparation. This helps align equipment configuration with the practical conditions found at the facility.

Commissioning support provides an opportunity to verify travel, controls, hydraulic operation, safety functions, and transfer alignment. Operator and maintenance handover can then be based on the installed configuration rather than generic operating assumptions.

Lifecycle Service Consideration

Nio Equipment provides after-sales support for the supplied industrial lifting system. A maintainable design requires access to the hydraulic power pack, pivot points, hoses, controls, anchors, and safety devices, so service considerations can be incorporated during layout development. This supports preventive maintenance and fault investigation over the operating life of the equipment.

For an accurate RFQ, buyers should provide the maximum load, load distribution, platform dimensions, required travel, power supply, operating environment, control requirements, safety expectations, and site floor details. Complete application information enables a more technically appropriate proposal and reduces uncertainty during installation.

Installation Guide

Application And Site Survey

Installation planning should begin with the complete material flow rather than only the lift footprint. The survey should identify the load, maximum weight, centre of gravity, transfer direction, loading equipment, required elevations, operating frequency, and relationship with nearby machines or conveyors. Available headroom and clearance throughout the full lift travel must also be verified.

Uneven loads, non-standard platforms, multiple landing positions, or complex automated interfaces require application-specific review. These conditions influence structural design, controls, guarding, and the safe loading sequence.

Floor And Anchor Requirements

The lift requires a level, reinforced concrete floor capable of supporting the equipment, rated load, and forces transmitted through the base frame and anchors. Surface anchors secure the frame in its operating position, so anchor selection and installation must correspond to the floor condition and engineered mounting arrangement. Non-reinforced or structurally uncertain floors should be evaluated before equipment placement.

No pit excavation is required for the normal floor-mounted configuration. The resulting collapsed platform height must be addressed through suitable access planning, transfer equipment, barriers, or other project-specific measures.

Footprint And Load Access

The installation area must accommodate the base frame, platform, power pack, controls, safety barriers, and maintenance access. Loading and unloading routes should allow forklifts, pallet trucks, carts, or conveyors to approach without striking the lift structure or controls. Clearance must remain available around moving parts and potential scissor-arm trapping zones.

Platform orientation should align with the intended transfer path and adjoining equipment. Where loads move across an edge, the project design should consider gates, railings, sensors, stops, and transfer sequencing.

Power Pack Placement

The hydraulic power pack should be positioned where it can be inspected and serviced without entering an unsafe area beneath or within the lift mechanism. Hose routes need protection from abrasion, crushing, excessive bending, traffic, and contamination. The arrangement should also permit access for oil-level checks, leak inspection, and component cleaning.

Power pack location may be integrated near the base or arranged according to site constraints and project design. Any remote arrangement should be engineered with appropriate hydraulic routing and protection.

Electrical And Control Connections

Electrical planning must match the configured supply: 230V single-phase, 415V three-phase, or battery DC. The motor rating will fall within the supported 2.2 kW to 7.5 kW range according to the selected lift, and the site connection must suit that project specification. Control-panel placement should give the operator a clear view of the platform and transfer area.

PLC, HMI, conveyor, wireless, or production-line integration requires defined input, output, interlock, and emergency-stop responsibilities. Electrical and automation work should be completed by appropriately qualified personnel using the approved project documentation.

Guarding And Safety Zones

Installation planning should provide space for safety railings, gates, photoelectric sensors, barriers, control stations, and marked exclusion zones as required by the application. Access beneath the raised platform and into scissor-arm movement areas must be controlled. Guarding should not obstruct normal material transfer or maintenance isolation procedures.

The appropriate arrangement varies between a pallet transfer station, operator workstation, conveyor interface, and multi-level transfer application. A site-specific risk review should therefore confirm the final protective measures.

Commissioning And Handover

After anchoring and connection, the lift should be commissioned through functional and safety testing before routine use. Checks should confirm platform movement, upper and lower travel limits, controls, emergency stop, overload protection, sensors, gates, hydraulic integrity, and safe transfer alignment. Testing should also verify that the lift remains stable and unobstructed throughout its designed travel.

Operator training and maintenance handover should cover intended use, rated loading, pre-use inspection, emergency response, isolation, and service access. Commissioning records and equipment documentation should be retained for future maintenance and safety reviews.

Maintenance Guide

Routine Condition Checks

Routine inspection should identify hydraulic leakage, damaged hoses, loose fasteners, platform damage, unusual movement, or contamination around the base frame. Operators should also note abnormal noise, vibration, hesitation, or changes in lifting and lowering behaviour. Early reporting helps prevent minor defects from developing into reliability or safety problems.

Inspection frequency should reflect operating intensity, environment, and the equipment documentation. The lift should not remain in service when observed damage could affect structural, hydraulic, control, or safety performance.

Hydraulic System Care

Hydraulic oil level and condition should be checked periodically, together with hoses, fittings, cylinders, and accessible seals. Signs of abrasion, cracking, leakage, or damaged routing require investigation before continued operation. Power pack components should be kept clean so that contamination and heat accumulation do not interfere with serviceability.

Hydraulic work must be performed only after the platform is safely supported and stored pressure has been addressed. Replacement fluids and components should follow the equipment documentation rather than being selected solely by visual similarity.

Scissor Structure Inspection

Scissor arms, pivot points, pins, welds, base frame, and platform structure should be examined for wear, deformation, cracking, corrosion, or impact damage. Pivot points require lubrication according to the prescribed maintenance procedure and operating conditions. Bolt torque and anchor condition should also be verified periodically.

Structural repair or modification should not be undertaken without engineering review. Changes to arm geometry, platform size, load position, or rated capacity can alter the forces carried by the complete mechanism.

Controls And Limit Devices

The control panel, operator switches, wiring, connectors, and power-supply components should be checked for damage and reliable response. Upper and lower travel limit switches must operate consistently so that the platform remains within the designed movement range. Photoelectric sensors and external automation interlocks should be tested as part of the complete operating sequence.

Control faults should be diagnosed by qualified personnel. Bypassing a sensor, limit switch, gate interlock, or other protective function is not an acceptable maintenance remedy.

Safety Function Testing

Emergency stop operation, overload protection, hydraulic hose burst protection, gates, railings, and relevant sensing devices require periodic functional verification. Testing should confirm not only that each device responds, but also that the resulting machine state is appropriate for the installation. Any failed or inconsistent function should be corrected before normal use resumes.

Maintenance records help track recurring issues and confirm that safety checks have been completed. Exact intervals should follow equipment documentation, usage conditions, and the site's preventive maintenance program.

Platform And Work Area

The platform surface should remain clean, structurally sound, and free from substances that could cause a load to slip. Edge components, gates, railings, and any conveyor or transfer attachments should be checked for alignment and damage. Debris should not be allowed to accumulate around the base, anchors, hydraulic equipment, or moving scissor mechanism.

Changes in adjoining machinery or floor layout should trigger a review of clearances and transfer alignment. A safe original installation can become unsuitable if storage, barriers, conveyors, or traffic routes are later altered.

Safety Guide

Trained Operator Control

Only trained personnel should operate the Floor Mounted Scissor Lift, using the controls and loading procedure defined for the installation. Operators must understand the rated capacity, intended load type, travel limits, exclusion zones, and emergency stop arrangement. The equipment should not be used for personnel transportation because its validated application is industrial load positioning.

Before each operating period, the user should check the platform, controls, visible hydraulic components, sensors, gates, and surrounding area. Unexpected movement, leaks, damage, or failed safety devices require the lift to be removed from service for assessment.

Rated Load Compliance

The total load, including pallets, tooling, fixtures, containers, and attachments, must remain within the configured rated capacity. Supported configurations range from 500 kg to 5,000 kg, but each installed lift has its own approved rating. Capacity must not be inferred from platform size or motor power.

Load distribution is as important as gross weight. Concentrated or offset loading can impose structural forces different from an evenly distributed load and should be assessed during equipment selection.

Stable Load Positioning

Loads should be placed in the approved position on the platform and restrained where their shape, height, or centre of gravity creates a movement risk. Transfer should begin only when the platform is correctly aligned with the loading point and is stationary. Operators should keep hands, feet, and loose materials clear of platform edges and scissor-arm trapping areas.

Pallets, carts, dies, and fixtures should be checked for stability before elevation. Damaged pallets, rolling loads, or unsecured components can create hazards even when their total weight is within capacity.

Access And Edge Protection

Safety railings, safety gates, photoelectric sensors, barriers, and marked safety zones can be applied according to the loading method and exposure at the installation. Gates and barriers should remain in their intended operating position and must not be bypassed for convenience. Access below a raised platform should be prohibited unless the lift is isolated and mechanically secured using the approved maintenance procedure.

Where the unit interfaces with conveyors or elevated transfer points, access control must cover both the lift and adjoining equipment. The final arrangement should be based on the site-specific risk assessment.

Emergency And Failure Protection

The emergency stop provides a means to halt lift motion when an unsafe condition is observed. Overload protection prevents operation beyond the configured lifting limit, while the hydraulic hose burst valve helps arrest uncontrolled descent following hose failure. Travel limit switches restrict movement to the intended operating range.

Operators should know the location and effect of emergency controls before using the lift. After any emergency stop or protective-device activation, the cause should be identified and corrected before restarting.

Maintenance Isolation Procedures

Maintenance must be performed with the electrical and hydraulic energy sources isolated according to the site's lockout and tagout procedure. A raised platform must not be supported solely by hydraulic pressure when personnel need access to the mechanism. Stored hydraulic energy and potential platform movement must be controlled before work begins.

Unauthorized changes to controls, hydraulic settings, structural members, platform dimensions, or safety devices are not permitted. Proposed modifications require engineering evaluation because they can affect capacity, stability, travel, and protective functions.
