A pallet jack, also known as a pallet truck or pump truck, is a manual or electric-powered tool used to lift and move palletized loads. Pallet jacks are commonly found in warehouses, distribution centers, and other industrial settings where the movement of heavy goods on pallets is required.

There are two main types of pallet jacks:

Manual Pallet Jack: This type of pallet jack is operated by a person who uses a pump handle to manually raise the forks of the jack, allowing it to slide underneath a pallet. Once the pallet is lifted, the operator can push or pull the pallet jack to move the load to a pallet jack different location. Manual pallet jacks are suitable for lighter loads and shorter distances.

Electric Pallet Jack: Electric pallet jacks, also known as powered pallet jacks or electric pallet trucks, are equipped with an electric motor that assists in lifting and moving heavy loads. These jacks are typically operated using controls on the handle, allowing the operator to maneuver the jack more easily and with less physical effort. Electric pallet jacks are ideal for larger and heavier loads as well as longer distances.

Pallet jacks are designed to work with standard-sized pallets and are not suitable for lifting loads higher than the pallet itself. For lifting loads to greater heights or for more complex material handling tasks, other equipment like forklifts or reach trucks might be used.

It's important to note that while pallet jacks are relatively simple to operate, proper training and safety precautions are necessary to avoid accidents and injuries.
