When to use a wheel-based restraint
Wheel-based restraints are effective in the following situations:

  • Trailers without NHTSA-approved RIGs.
  • 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.
