A wedge or similar device inserted in a space adjacent to an object, to hold the object steady. Any place you see workers around a stopped truck, you may see a chock placed near the rear wheel. OSHA requires that work vehicles be chocked. OSHA compliant truck chocks are required.
OSHA requires drivers to set the brakes and that workers chock the rear tires of trucks before they are loaded or unloaded. If a driver detaches a trailer from his truck he must stabilize the trailer with jacks and chock the rear wheels, even a railcar can be blocked using railcar chocks or blocks.
Using OSHA Compliant Truck Chocks is a great practice. The old block of wood is being replaced by modern, completely compliant, visible chocks.
The OSHA directive and guidance for chocking is 29 CFR 1910.178(k)(1) and (m)(7): Mechanical Means to Secure Trucks or Trailers to a Loading Dock
Reviewing this guidance for chocking a truck when it is being loaded or unloaded. Remember that government agencies like OSHA update guidance directives from time to time.
Chocks are not what they used to be. The old wedge of wood is still around but modern, high visibility truck wheel chocks and steel and urethane railcar chocks from suppliers like Aldon are now the norms.
The purpose of chocking a truck is to prevent a truck from being able to back up inadvertently. Trucks should be fully braked before the chock is inserted near a wheel.
The modern wheel immobilizers are corrosion-resistant, spark-resistant (static electricity), and powder-coated for a very long life. Modern chocks keep your loading/unloading operation OSHA compliant. These are the best wheel chocks for trucks.
Worker safety in any loading-unloading area should be the number one priority. Visible, static resistant chocking in fuel loading areas should be a robust practice for all hands. Modern chocks can be folded and stored in truck compartments and in areas near a loading/unloading area.
Wheel chocks (or even chocks) are wedges of hardy material placed tightly against an automobile’s wheels to stop the unintentional movement. Chocks are put for security as well as placing up the brakes. The base surface is occasionally coated in rubber to boost grip with the floor. For ease of elimination, a rope could possibly be tied into the chock or some pair of 2 chocks. 1 advantage of the wedge includes a concave profile to shape the wheel and boost the force required to overrun the chock.
Automobiles usually possess parking wheels on the back wheels. If the back axle is jacked off the floor with just the parking brake set, the car may roll onto the front wheels and collapse. Chocking front wheels prevents this particular mishap.
The mining industry employs wheel chocks to shield lubrication trucks and heavy care vehicles by falling on off-road terrain once positioned in Park. The massive haul trucks, which may weigh up to 450 tons, need a far bigger wheel that itself will weigh nearly 40 kilograms. These conditions will profit out of urethane wheel chocks which are lightweight enough to be maneuvered, yet can defy the duty of holding a vehicle in case a brake should neglect. The Mine Safety and Health Administration (MSHA) has established criteria that wheel chocks are utilized when a car is parked on a regular, and OSHA includes guidelines which need wheel chocks during unloading or loading using a heavy truck.
