• Trailers with damaged or bent RIGs.
• Trailers with hydraulic lift gates.
• Trailers with low-hanging fenders.

Wheel chocks are not the answer
Wheel chocks cannot protect across the range of hazards at the loading dock. There are many problems associated with wheel chocks:

• Slip on oily surfaces, rain, snow or ice.
• Can’t prevent a sudden departure.
• Can be easily driven over.
• Lack a communication system to alert the truck driver and lift truck operator.
• Easily lost, misplaced or stolen.
• Need to stock multiple sizes.
• Require training and supervision.
• Dangerous and time-consuming installation.
