The taller the bin is, the further away from the forks the top of the bin rotates.
This increases all the torque racking on the gear and on the fork rotation pockets themselves. It also means the forklift operator is further away from the hopper or truck in directing the flow of bin contents when emptying.
If you have a very heavy load for continual rotation empty, it follows best principles to have a low height bin, so it rotates through a smaller radius around the forks. This is where the PLAST-AX heavy duty box pallet bins come in, designed for the extreme weight of heavy wet hides in tanneries.
