About This Product

The Manual Hydraulic Stacker is a manually propelled material handling unit designed to raise, position, stack, and transfer palletized loads over short distances. It combines manual push-pull travel with a hydraulic lifting mechanism, providing vertical handling capability without batteries, electrical connections, or external hydraulic services. The equipment is suited to low- and medium-frequency workflows where controlled pallet elevation is required but a powered forklift or electric stacker may not be operationally justified.

Typical operating environments include warehouses, production facilities, packaging areas, dispatch zones, and industrial stores with level floors. The compact chassis and manual steering arrangement support maneuvering through constrained work areas, while the mast, forks, and fabricated frame provide the structural path needed to support loads during lifting and positioning.

Hydraulic Lifting Principle

Mechanical force applied through the hand lever or foot pedal operates the manual hydraulic pump. Hydraulic pressure actuates the cylinder, which raises the fork carriage through the mast assembly until the required pallet position is reached. A controlled descent valve regulates pressure release during lowering, helping the operator place the load smoothly rather than allowing an abrupt drop.

This lifting principle keeps the equipment mechanically straightforward and independent of charging infrastructure. Manual traction remains necessary for horizontal travel, so the stacker is most effective where travel distances are short, floors are smooth, and handling cycles are intermittent.

Vertical Material Flow

Unlike a hand pallet truck intended mainly for horizontal transport, the Manual Hydraulic Stacker can lift pallets to rack, staging, production, or workstation heights. Available lift heights range from 1,600 mm to 3,000 mm, allowing the selected configuration to support common low-level stacking and material positioning requirements. This vertical capability can reduce dependence on forklifts or cranes for routine pallet placement within appropriately assessed applications.

The equipment can connect receiving, storage, production, packaging, and dispatch activities by allowing a pallet to be moved and elevated with one manually operated unit. It is particularly relevant where facilities need to use vertical storage more effectively without introducing powered traction equipment into every handling zone.

Appropriate Operating Profile

The stacker is intended for indoor industrial operation on level, stable surfaces with adequate maneuvering and overhead clearance. Its supported capacity range is 500 kg to 2,000 kg, subject to selection around actual pallet weight, load distribution, lift height, and operating conditions. Fork dimensions, mast configuration, adjustable fork spacing, and wheel material can be selected to suit the intended pallet interface and facility layout.

It is not the preferred choice for long travel routes, inclined floors, continuous high-frequency duty, or loads above 2,000 kg. Applications involving uneven surfaces, restricted operator capability, unusual load distribution, or lift heights above 3,000 mm require further assessment and may be better served by semi-electric, electric, straddle, or counterbalance equipment.

Applications

Pallet Rack Stacking

In warehouse rack workflows, the operator positions the adjustable forks beneath a compatible pallet, raises it to the required storage level, and aligns it with the rack location. Lift height must be matched to the rack beam level, while aisle width and mast clearance must permit safe approach and withdrawal. The controlled lowering arrangement assists with deliberate pallet placement onto the rack support.

This application is most appropriate for low- to medium-frequency replenishment where pallet weights remain within the selected capacity. Rack geometry, pallet condition, load stability, and operator visibility should be reviewed before the stacker is specified.

Inventory Replenishment

The Manual Hydraulic Stacker can move reserve pallets from a storage or staging position to picking, packing, or workstation locations. Its vertical lift allows inventory to be transferred between floor level and an elevated operating height, reducing the need to unpack and manually raise individual cartons or containers. Manual travel is well suited to compact replenishment routes within a defined warehouse zone.

For mixed pallet operations, adjustable fork spacing can accommodate different pallet openings when correctly configured. Fork length and load-center compatibility must still be checked for each regularly handled pallet type.

Production Line Supply

Manufacturing teams can use the stacker to deliver palletized raw materials, components, packaging supplies, or sub-assemblies to production cells. The load can be positioned at a practical transfer height beside an assembly or processing station, supporting more orderly material presentation and reducing repeated floor-level handling. After unloading, the empty stacker can be returned manually to the staging area.

The configuration should reflect the weight and footprint of the production load, the required workstation height, and the available turning space. High-cycle line feeding or long routes may justify evaluation of a semi-electric or electric stacker instead.

Work In Progress Transfer

Machined parts, fabricated components, fixtures, and other work-in-progress items are often moved between processing, inspection, assembly, and temporary storage areas. A Manual Hydraulic Stacker supports these transfers when the items are securely palletized and suitable for fork handling. Vertical positioning can help interface the pallet with storage levels or designated receiving heights between process stages.

Where loads are concentrated, irregular, or unevenly distributed, rated pallet weight alone is not sufficient for selection. The load footprint, balance, fork support, and backrest interaction should be evaluated before handling.

Finished Goods Movement

Finished product pallets can be transferred from packaging areas to warehouse storage, dispatch staging, or loading preparation zones. The stacker enables short-distance movement and controlled elevation without waiting for a powered forklift to become available. This can help maintain continuity between the end of a packaging line and the next storage or dispatch step.

The unit is suitable for positioning loads within a facility, but it should not be treated as a powered transport vehicle for long travel distances. Loading dock use requires level operating surfaces, sufficient edge protection, and a defined safe route away from gradients.

Raw Material Handling

Palletized production materials can be received into a stores area, moved to floor-level staging, or raised into low-level storage positions. The heavy-duty fabricated mast and load-bearing frame support controlled vertical movement within the selected capacity. Manual operation can be practical in stores where movement is intermittent and electrical charging facilities are undesirable.

Material packaging must remain stable throughout lifting and travel. Bags, cartons, containers, or loose components should be secured to prevent shifting, particularly when the forks are raised.

Packaging Area Handling

Packaging operations frequently require movement of cartons, crates, secondary packaging materials, and completed product pallets between work areas. The Manual Hydraulic Stacker can position these loads at packing, wrapping, or accumulation points and then transfer finished pallets into staging. Its compact chassis is useful where packaging equipment and temporary inventory restrict maneuvering space.

The operator should lower the load for travel and raise it only when positioning is required. Selected wheel material should account for floor protection, operating noise, rolling resistance, and traction within the packaging environment.

Dispatch Load Positioning

In dispatch areas, the stacker can organize outbound pallets, position loads within staging lanes, and place goods at an appropriate transfer height. It can also support cross-docking or receiving workflows where pallets need controlled short-range repositioning between designated zones. Parking brakes help secure the equipment when it is stationary during loading or unloading.

The stacker is not intended for travel on dock ramps or inclined surfaces. If dispatch routes involve extended travel, gradients, or sustained throughput, powered alternatives should be considered during equipment selection.

Benefits

Lower Infrastructure Demand

Manual hydraulic lifting and manual traction eliminate the need for batteries, chargers, electrical outlets, or an external hydraulic power source. This simplifies deployment in suitable warehouse and production areas and avoids charging-related operating routines. The mechanically straightforward system can also reduce maintenance complexity compared with fully powered handling equipment.

These advantages apply most strongly to intermittent, short-distance workflows. They should be balanced against the operator effort and lower cycle rate associated with manual travel and pumping.

Controlled Load Positioning

The mast-guided fork arrangement allows palletized goods to be raised from floor level and aligned with racks, workstations, or staging positions. Controlled hydraulic descent supports measured lowering, helping the operator place the pallet without sudden vertical movement. Adjustable fork spacing further improves compatibility with different pallet openings and load footprints.

More accurate positioning can reduce avoidable load contact with racks, production equipment, or adjacent stock. Safe results still depend on correct equipment selection, stable loads, suitable floors, and trained operation.

Improved Handling Ergonomics

Using a hydraulic cylinder to generate vertical movement reduces the need for personnel to lift palletized materials directly. Dual hand and foot pumping gives the operator a choice of input method, while the ergonomic steering handle supports controlled manual maneuvering. Well-maintained wheels and pivot points are important because rolling condition directly affects pushing effort.

The stacker reduces certain manual lifting demands but does not eliminate physical effort. Operator capability, load weight, route length, and floor resistance must therefore be considered when deciding between manual and powered traction.

Better Space Utilization

Lift heights from 1,600 mm to 3,000 mm allow the selected stacker to place loads above floor-level staging where compatible storage arrangements are available. This supports more effective use of vertical warehouse space and can reduce congestion caused by keeping all inventory at ground level. The compact chassis also supports operation in constrained aisles where a larger forklift may be difficult to maneuver.

Storage improvement depends on matching the mast and fork elevation to actual rack levels and collapsed-height restrictions. Overhead clearance and aisle geometry must be confirmed as part of the site assessment.

Flexible Pallet Handling

Capacity, lift height, fork dimensions, fork spacing, mast arrangement, and wheel material can be selected around the intended application. This allows the Manual Pallet Stacker to be configured for different pallet depths, rack heights, floor conditions, and operating environments rather than relying on a single general-purpose arrangement. Single-stage or duplex mast options also help balance required elevation against collapsed-height and overhead constraints.

Configuration flexibility does not remove the need for engineering review. Non-standard pallets, uneven load distribution, unusually narrow aisles, or specialized forks should be qualified before an order is finalized.

Technical Highlights

Capacity And Lift Range

The supported load-capacity range extends from 500 kg to 2,000 kg, while maximum lift height can be selected from 1,600 mm to 3,000 mm. These values define the available product range rather than permission to handle every load at every operating condition. Selection should account for maximum pallet mass, weight distribution, load footprint, stacking height, and handling frequency.

Loads above 2,000 kg or lift requirements beyond 3,000 mm require application review and may call for a different type of stacker. The equipment's rated capacity label and supplied documentation govern operation of the delivered configuration.

Manual Hydraulic System

A hand-operated hydraulic pump converts lever or pedal input into pressure that actuates the lifting cylinder. Dual hand and foot pumping provides operational flexibility during fork elevation, while lowering is managed through a controlled descent valve. Hydraulic overload relief helps prevent lifting beyond the system's intended load condition.

Because both lift input and travel are manual, the stacker needs no battery or electric traction system. This favors uncomplicated, intermittent use but limits suitability for continuous high-cycle service or extensive travel.

Mast And Frame Construction

The load path is supported by a heavy-duty fabricated steel mast, precision-welded load-bearing frame, fork carriage, and hydraulic lifting assembly. A single-stage or duplex mast can be selected according to required lift height, collapsed height, and available overhead clearance. The stable wheelbase and structural frame support controlled vertical load guidance when the equipment is used on a level surface.

A mast chain guard limits operator access to the chain area, while the load backrest helps stabilize the palletized load. These components require regular inspection because wear, damage, or misalignment can affect lifting safety.

Fork Interface Options

Lowered fork height is available from 85 mm to 90 mm, and fork length can range from 900 mm to 1,150 mm. Adjustable fork width extends from 300 mm to 850 mm, allowing the fork position to be matched to supported pallet entry openings and load widths. Final dimensions should be selected from actual pallet measurements rather than nominal pallet descriptions alone.

Correct fork engagement is essential for load support and stability. Pallet depth, entry direction, underside clearance, load center, and structural condition should all be reviewed during specification.

Manual Travel Arrangement

Horizontal movement is achieved through manual push and pull using an ergonomic steering handle. The compact chassis assists maneuvering in warehouse aisles, production cells, and staging zones where travel distances remain short. Manual traction also means that rolling resistance, floor joints, debris, gradients, and operator capability materially influence usability.

Polyurethane, nylon, or rubber wheels can be selected according to the application. Polyurethane can support quieter movement and floor protection, nylon offers low rolling resistance and durability on suitable surfaces, and rubber can provide added traction under compatible conditions.

Integrated Safety Provisions

Supported safety features include hydraulic overload relief, a parking brake, mast chain guard, foot protection guards, controlled descent valve, and load backrest. Together, these features address overload attempts, unintended stationary movement, contact with moving mast components, foot exposure, abrupt lowering, and rearward load movement. They supplement rather than replace operator training, route control, and correct pallet handling.

Clear visibility of the forks and load remains important during approach and stacking. Safety labels, guards, brakes, and descent controls should be checked before operation and kept in serviceable condition.

Industries Served

Warehousing And Fulfillment

Warehouses and e-commerce fulfillment facilities use the stacker for rack replenishment, order-picking pallet support, reserve inventory movement, and staging-area transfers. Common loads include stock pallets, finished goods, packaging materials, and consolidated outbound orders. Vertical lifting helps connect floor-level receiving or picking zones with compatible storage levels.

A compact manual warehouse stacker is most useful where aisles are constrained, routes are short, and cycles are moderate. Fork and mast selection should reflect the facility's pallet standards and rack heights.

Manufacturing Operations

Manufacturing facilities can apply the stacker to raw-material supply, component delivery, work-in-progress movement, finished-goods stacking, and packaging-zone transfers. Palletized loads can be moved between stores, production cells, assembly areas, and temporary staging positions without requiring electrical power. The ability to elevate the load also supports alignment with suitable workstation or storage heights.

For frequent production-line feeding, operator effort and cycle demand should be reviewed carefully. Powered equipment may be more appropriate where uninterrupted throughput or long routes are central to the process.

Automotive And Engineering

Automotive and engineering operations handle palletized components, tooling fixtures, fabricated parts, machined items, and sub-assemblies between production stages. The stacker can position these loads beside assembly cells, inspection stations, tooling stores, or low-level racks. Adjustable fork spacing is useful when several pallet or fixture footprints are present.

Dense or irregular engineering loads require close attention to weight concentration and support beneath the load. Nio Equipment can assess specialized fork dimensions or load interfaces when standard pallet geometry is unsuitable.

FMCG And Packaging

FMCG and packaging facilities commonly move cartons, crates, packaged consumer products, wrapping supplies, and production support materials. The stacker can supply packaging lines, raise completed pallets for storage, and organize loads in dispatch staging. Manual hydraulic operation suits designated indoor zones where handling is intermittent and floors are well maintained.

Wheel material can be selected around floor protection, noise, traction, and rolling effort. Fork spacing and length should be matched to the pallets used for cartons or packaged goods.

Pharmaceutical Material Handling

Pharmaceutical facilities may use the stacker for secondary packaging materials, cartons, containers, production support supplies, and packaged product pallets. It can support controlled transfer between permitted operational zones, replenishment at workstations, storage positioning, and dispatch staging. Manual operation avoids battery charging within the immediate workflow, although facility-specific hygiene and access procedures still apply.

The stacker is intended for limited exposure to dust and moisture and should be maintained in a clean condition. Suitability for a particular controlled area must be assessed against the site's environmental and material-handling requirements.

Distribution And Logistics

Distribution and logistics operations use pallet handling equipment to connect receiving, storage, staging, and dispatch activities. The Manual Hydraulic Stacker can reposition inbound shipments, place pallets at storage levels, replenish operational zones, and organize outbound loads. Its controlled vertical movement supports accurate placement where a hand pallet truck cannot provide sufficient lift.

Manual traction is appropriate for short-distance movement across flat operational floors. Cross-dock layouts involving long routes, ramps, or rapid continuous cycles should be evaluated for electric or semi-electric alternatives.

Food And Retail Storage

Food processing support areas and retail warehouses can use the stacker for packaged ingredients, cartons, containers, finished products, and shelf-replenishment pallets. It supports movement between storage, packaging, inventory, and dispatch zones where loads are palletized and the operating environment is suitable. Controlled positioning can reduce repeated manual transfer of individual packages between floor and storage levels.

Wheel and material choices should reflect floor condition, cleaning practices, moisture exposure, and noise requirements. The standard operating context remains an indoor environment with limited dust and moisture, so more demanding exposure conditions require application review.

Why Choose NIO Equipment

Application Focused Selection

Nio Equipment approaches Manual Hydraulic Stacker selection around the actual load, pallet, route, rack height, floor condition, and handling frequency. This helps buyers distinguish between a suitable manual stacker application and one that requires semi-electric, electric, straddle, or counterbalance equipment. Site-specific selection support is particularly valuable where aisle geometry, operator capability, or uneven load distribution affects feasibility.

The result is an equipment specification connected to the intended workflow rather than capacity alone. Procurement teams can use this approach to define a clearer technical scope before requesting a quotation.

Configurable Pallet Interface

Nio Equipment can configure capacity, lift height, fork dimensions, adjustable fork spacing, mast arrangement, and wheel material according to application requirements. Supported choices include capacities from 500 kg to 2,000 kg, lift heights from 1,600 mm to 3,000 mm, single-stage or duplex masts, and polyurethane, nylon, or rubber wheels. These options allow the stacker to be aligned with pallet entry, rack levels, overhead clearance, and floor characteristics.

Specialized dimensions, higher loads, or non-standard operating conditions remain subject to engineering evaluation. This distinction helps prevent optional or project-specific features from being assumed to be standard.

Manufacturing And Hydraulic Capability

Nio Equipment manufactures industrial material handling and hydraulic lifting equipment in Pune, Maharashtra, India. Its capabilities include custom equipment design, manufacturing, and practical hydraulic system integration, supporting coordinated consideration of the pump, cylinder, mast, frame, forks, wheels, and operator controls. This manufacturing orientation is relevant when a standard catalogue arrangement does not fully match the pallet or facility.

Application-based configuration can also address compact chassis needs, ergonomic steering arrangements, fork selection, and mast requirements. Any variation should be confirmed against structural, hydraulic, stability, and operating constraints.

Lifecycle Support

Nio Equipment provides installation support, commissioning support, and after-sales service coverage within India. For a manually operated stacker, this support can include site-readiness review, functional checks, operating guidance, and maintenance planning around the hydraulic system, mast, wheels, brakes, guards, and frame. Proper handover helps operators understand both the equipment's capabilities and its limitations.

Buyers preparing an RFQ should provide maximum load weight, load distribution, lift height, pallet dimensions, aisle width, floor condition, travel distance, handling frequency, environmental exposure, and preferred configurations. Complete application data enables a more accurate assessment and helps identify when a powered alternative or engineered modification should be considered.

Installation Guide

Site And Route Assessment

Before commissioning, review the complete route between pallet pickup, travel, lifting, unloading, and parking positions. Floors must be level, stable, and sufficiently smooth for manual push-pull movement, with no ramps or inclined sections in the operating path. Doorways, aisle intersections, rack faces, workstations, and pedestrian routes should provide adequate clearance.

Long travel distances, uneven floors, or frequent congestion can make manual traction unsuitable even when the stacker physically fits. Such conditions should trigger evaluation of powered alternatives or revisions to the material flow plan.

Aisle And Turning Clearance

The operating space must accommodate the stacker chassis, pallet dimensions, steering movement, and the turning path required for alignment. Narrow aisles should be checked using actual proposed equipment dimensions rather than assuming that a compact chassis will fit every layout. Clearance is also needed to insert and withdraw forks without contacting racks, guards, or adjacent inventory.

If the available aisle is narrower than typical compact stacker geometry, project-specific sizing should be discussed with Nio Equipment. Custom chassis or fork requirements remain subject to engineering evaluation.

Lift And Overhead Clearance

Required maximum fork elevation should be established from the highest rack beam, workstation interface, or stacking level. The selected 1,600 mm to 3,000 mm lift range must be considered together with mast height, load height, ceiling clearance, services, lighting, doorways, and other overhead obstructions. A single-stage or duplex mast can then be chosen around both operating and collapsed-height constraints.

Applications requiring elevation above 3,000 mm or complex multi-level stacking fall outside the standard stated range. These conditions require consultation before equipment selection.

Floor And Foundation Conditions

The Manual Hydraulic Stacker does not require a specialized foundation, pit, shaft, or permanent support structure. It does require a sound floor capable of supporting the combined equipment and loaded pallet during travel, turning, and stationary lifting. Damaged joints, loose surfaces, abrupt level changes, and debris can increase pushing force or disrupt load stability.

Floor suitability should be confirmed as part of the facility assessment. Wheel material may then be chosen according to rolling resistance, noise, floor protection, traction, and environmental exposure.

Pallet Interface Verification

Fork length, lowered height, adjustable spacing, and pallet entry arrangement must be verified before the stacker enters service. The available fork length range is 900 mm to 1,150 mm, with a lowered height of 85 mm to 90 mm and adjustable width from 300 mm to 850 mm. The chosen geometry should provide adequate pallet support without creating unstable projection or incomplete engagement.

Representative pallets and loads should be used during commissioning checks. Damaged pallets, blocked fork openings, or irregular load distribution should be addressed rather than compensated for through unsafe positioning.

Commissioning And Handover

No electrical connection or external hydraulic service is required, which simplifies physical deployment. Commissioning should nevertheless verify hydraulic lifting, controlled descent, parking brake performance, steering, wheel movement, fork adjustment, mast guidance, guards, and load-backrest condition. Functional testing should begin without a load and progress to an appropriate controlled load in accordance with the supplied equipment documentation.

Operators should receive training before regular use, including capacity limits, fork positioning, pumping, lowering, travel technique, parking, and pre-use inspection. A designated storage area and accessible maintenance space should also be established during handover.

Maintenance Guide

Routine Condition Inspection

Routine inspection should identify hydraulic leakage, visible structural damage, loose fasteners, worn wheels, damaged forks, and abnormal mast movement before these conditions affect safe operation. Operators should also note unusual noise, increased pumping effort, steering resistance, vibration, or uneven lowering. Inspection frequency should reflect usage, load severity, floor conditions, and the equipment documentation.

Defects affecting lifting, braking, steering, guards, or load support should be corrected before the stacker returns to service. Maintenance findings should be recorded to support preventive planning.

Hydraulic System Care

Hydraulic oil condition and level should be checked periodically, together with the pump, cylinder, seals, and visible connections. Leakage, drift, slow lifting, spongy pump action, or irregular descent can indicate contamination, seal wear, trapped air, or a control-valve issue. Hydraulic components should be kept clean so that dirt does not enter service points.

The controlled descent valve and overload-relief function should be examined by qualified personnel according to the equipment documentation. Adjustments to pressure-control components should not be made by untrained operators.

Mast And Chain Checks

The mast, carriage, chain, chain guard, and load backrest should be inspected for wear, deformation, corrosion, misalignment, or damaged attachment points. Pivot points and designated moving interfaces require lubrication as recommended for the delivered unit. Smooth, even carriage travel is important because binding or unequal movement can affect positioning and structural loading.

The precision-welded frame and mast connections should also be examined for cracks or permanent distortion. Unauthorized welding, drilling, or structural repair can alter the load path and should not be undertaken without engineering approval.

Wheels Brakes And Steering

Wheel tread condition, axle alignment, bearings, steering action, and debris accumulation directly influence manual pushing effort. Worn or damaged wheels can increase operator fatigue and make accurate pallet alignment more difficult. Replacement wheel material should remain compatible with the floor, load, and operating environment.

The parking brake must hold the stacker securely when stationary. Foot protection guards and the ergonomic steering handle should remain intact, securely fastened, and free from damage that could compromise safe control.

Fork And Fastener Integrity

Forks should be inspected for bending, cracking, excessive wear, unequal height, or damage at adjustment and attachment points. Adjustable fork spacing mechanisms must move correctly and remain secure at the selected position. The load backrest should be checked for deformation and reliable attachment to the carriage.

Fasteners throughout the frame, mast, handle, guards, and hydraulic assembly should be checked and tightened as appropriate during routine maintenance. Before maintenance begins, the stacker should be unloaded, lowered to a safe position, secured against movement, and isolated from unintended operation.

Safety Guide

Trained Operator Control

Only trained personnel should operate the Manual Hydraulic Stacker. Training should cover pallet engagement, hydraulic pumping, controlled lowering, steering, parking-brake use, travel with the load lowered, and recognition of unsafe floor or load conditions. The unit must not be used to lift or transport personnel.

Pedestrians should be kept clear of the load, forks, mast, and maneuvering envelope. Operators should maintain visibility and use controlled movements when approaching racks, workstations, or staging positions.

Capacity And Load Stability

The rated capacity of the delivered stacker must never be exceeded, even when the hydraulic system appears capable of raising the load. Weight distribution, pallet condition, load height, fork engagement, and load footprint all influence stability. Loads should be centered across both forks and secured against shifting before lifting or travel.

Hydraulic overload relief provides protection against excess lifting attempts but is not a substitute for knowing the load weight. Unevenly distributed or unusual loads require assessment before handling.

Safe Travel Practices

Loads should be carried at the lowest practical travel position and raised only when the stacker is correctly aligned for placement. Travel must be limited to level, stable floors because the unit has no powered traction for controlling movement on ramps. Sudden turning, abrupt stopping, or pushing across damaged surfaces can reduce stability and increase operator effort.

The parking brake should be applied whenever the stacker is stationary for loading, unloading, positioning, or parking. Hands and feet must remain clear of wheels, forks, mast chains, and other moving components.

Controlled Lifting And Lowering

Before lifting, the operator should confirm full fork engagement, adequate overhead clearance, and a clear area around the pallet and mast. The load backrest helps resist rearward load movement, while the mast chain guard and foot protection guards reduce exposure to identified mechanical hazards. Guards must not be removed or bypassed during operation.

Lowering should be performed gradually through the controlled descent valve. No person should stand beneath raised forks or reach into the mast assembly, regardless of whether the stacker is loaded.

Inspection And Safe Maintenance

A pre-use check should cover the hydraulic system, forks, mast, chain guard, load backrest, wheels, steering handle, parking brake, foot guards, and capacity markings. Any leak, structural damage, uncontrolled descent, brake failure, or abnormal movement requires withdrawal from service until corrected. Unauthorized modifications to forks, frame, mast, hydraulic controls, or safety devices are not acceptable.

Maintenance must be performed with the load removed, forks safely lowered, and the stacker secured against movement. Where work requires access around raised components, approved mechanical support and the service procedures in the equipment documentation are necessary.
