An overview of electric pallet jacks
Electric pallet jacks are also commonly called powered pallet trucks, walkies, single or double pallet jacks. These pallet jacks are motorized to permit lifting and transporting of heavier and stacked loads. These usually contain a platform for the operator to stand while moving pallets around a warehouse or loading/unloading trucks.
The electric pallet jack is normally moved by a throttle on the handle to move forward or in reverse and steered by swinging the handle in the intended direction. Some contain a type of dead man’s switch rather than a brake to stop the machine should the user need to stop quickly or leave the machine while it is in use. Others use a system known as ‘plugging’ where in the driver turns the throttle from forward to reverse (or vice-versa) to slow and stop the machine, as the dead man’s switch is used in emergencies only.
