I have spent many hours working in various warehouses. Each warehouse had it's similarities and differences. They were all about moving and storing products of every size and shape imaginable. If there was one tool that made life easier for me, it would have to be the pallet jack.
Pallet jacks allow you to move whole loaded pallets without a fork lift. They are for ground level only and they are a huge time saver. The process is simple. You just slide the pallet truck underneath the pallet and then jack the pallet up. From there you just push the pallet truck and the whole pallet goes with it. It can be a little tricky at first maneuvering in and out of tight places but once you get the hang of it, pallet trucks become your best friend.
There are a few different types of pallet trucks to consider. The more expensive models are electric and require little to no actual physical effort to use and move. You push a button and it lifts the pallet and then you use the on board controls to move and steer the pallet into place. These are great and anyone can use them regardless of their strength and size.
Hydraulic pallet trucks are the most common. They are less expensive than the electric models and they work just as well. It does require more strength to get them moving but there are less parts to break. They use a hydraulic piston to lift the forks of the pallet jack off the floor.
