Why Not Use a Regular Hand Truck?
With a hand truck, you need to push a stack of boxes forward in order to squeeze the shoe under the stack. This can make the stack unstable. A pallet system keeps the load upright and stable until the truck is locked into position for moving. The shoe of a regular hand truck is fixed, which limits its use in tight quarters. Standard stackable containers tend to slide around on a regular hand truck when full because the bottom of the container has a smaller footprint than the top. But using a pallet underneath the standard containers, you eliminate the sliding.
