Wheel chock

If the rear axle is jacked off the ground with only the parking brake set, the vehicle may roll on the front wheels and fall.

The mining industry uses wheel chocks to protect lubrication trucks and heavy maintenance vehicles from slipping on off-road terrain when placed in Park.

These circumstances will benefit from urethane wheel chocks that are lightweight enough to be maneuvered, yet can withstand the responsibility of holding a truck if a brake should fail.

The Mine Safety and Health Administration (MSHA) has established standards that wheel chocks are used when a vehicle is parked on a grade, and Occupational Safety and Health Administration (OSHA) has guidelines that require wheel chocks during loading or unloading of a heavy truck.

This lighter version can be installed by one person and will resist auto oils and fuels and will never need maintenance such as repainting.
