Chocking

Chocking refers to the process of securing a load, such as a vehicle or shipping container, to prevent it from moving. This is typically achieved by placing chocks, which are wedge-shaped blocks, against the wheels or base of the object. Chocks are designed to fit snugly and provide a physical barrier that resists rolling or sliding.

The primary purpose of chocking is safety. When a vehicle is parked on an incline, or when a cargo is being loaded or unloaded, chocking prevents accidental movement that could lead to damage or injury. For example, in maritime shipping, cargo containers are often chocked to ensure they remain stable on the deck of a ship during transit, even in rough seas. Similarly, on construction sites, heavy equipment is chocked when parked to prevent it from rolling downhill.

Chocks can be made from various materials, including rubber, wood, or metal, depending on the application and the weight of the object being secured. The size and shape of the chock are critical for effective restraint. Proper placement is also essential; chocks should be positioned on both sides of a wheel or at multiple points of contact for maximum stability. Regular inspection of chocks for wear and tear is important to ensure their continued effectiveness.
