Do not push pallets with power jacks. The drive system is not capable of this type of resistance. Lift no more than the capacity of the machine. Tape, twine and strapping get caught in equipment wheels. Dirt, wood chips and debris cause wheels to lock up and create flat spots.
Cardboard can make any floor an ice rink.
Straighten pallets to avoid pushing the pallet with the next put away. Install safety bars so pallet loads will not fall between the load beams. Leave at least 4 inches on either side and top of every pallet for proper clearance. Nothing can take the place of proper training and quality hiring practices. However, if you think something is not possible a warehouse employee will find a way.
