Made of cast aluminum, rubber or urethane, wheel chocks attempt to minimize accidental trailer movement from fork truck jolts and vehicle brake failure. Wheel chocks can not 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.
