How Does a Pallet Jack Work?

Pallet jacks utilize mechanical and hydraulic systems to lift and transport palletized loads efficiently.

Lifting and Lowering Mechanism

All pallet jacks, whether manual, electric, or powered, incorporate a hydraulic mechanism for lifting and lowering loads. When the operator pumps the control handle or lever, hydraulic fluid is pressurized within the cylinder. It extends the forks upwards, lifting the pallet and any items loaded off the ground.

The two durable forks are inserted underneath the pallet to support the weight. To lower the load, a release mechanism returns the hydraulic fluid to the reservoir, causing the forks to descend and gently lower the pallet in the desired location within its intended short distance of movement.

This enables single-person operations to quickly move even heavy palletized loads in warehouses and between facilities.

Maneuvering and Steering

Pallet jacks are highly maneuverable to transport palletized loads within short distances easily. The operator can use the control lever or handle to steer the wheels in the intended direction through narrow aisles around tight corners and stacked pallets. Electric models offer additional functionality via horizontal movement controls for precise steering.

Safety Features

• Overload protection systems to avoid exceeding maximum weight capacity
• Brakes to prevent uncontrolled movement of loaded jacks on ramps or slopes
• Audible alarms and visual indicators to warn operators of faults
• Emergency stop buttons for immediate shut-off during malfunctions
• Ergonomic handles positioned for operator comfort and complete visibility of loads
• Non-slip load wheels and broad base for stability when moving loads in all directions
• Reflective elements, lights, or markings for visibility in low-light warehouses

These features help ensure safe operation around other material-handling equipment in confined spaces of warehouses, loading docks, and construction sites.
