They are unconditionally guaranteed against breakage. Available with holders for every application, Sauber All-Weather Wheel Chocks are protecting people and property 32 years after we designed and patented them.
The capacities in the table below are based on the recommended practice of placing two chocks at each non-steering axle, one set on both the right and left side of the vehicle, blocking the tire in the direction of the incline. Note that the U.S. Department of Transportation provides that the maximum single-axle weight limit on Federal highways is 20,000 lbs. The tandem-axle limit is 34,000 lbs. in combination, with some exceptions up to 40,000 lbs. at very wide axle spreads. Some states may allow higher weights due to “grandfather” rights.
