Automatic wheel chock

Types of Automatic Wheel Chock

An automatic wheel chock, also known as a wheel block or wheel brace, is a wedge or block placed against the wheels of a vehicle to prevent it from moving. This can be due to the terrain, slope, or soft ground. The wheel chock is often used in conjunction with the parking brake, particularly on sloped ground, to provide an extra layer of security and safety against unwanted vehicle movement. Automatic wheel chocks can be manual, but they can also be self-acting or self-applying, where they deploy automatically when the vehicle is stationary, providing additional safety. The types of automatic wheel chocks include the following:

• Manual wheel chocks: These require a person to place them against the wheels of the vehicle to prevent movement. They are usually made of wood or metal.
• Mechanical wheel chocks: These are placed against the wheels of vehicles with low traffic movement, such as golf carts or forklifts. They are spring-loaded and engage automatically when the vehicle is stopped, preventing movement.
• Self-energizing wheel chocks: These are designed for larger vehicles, such as trucks or buses. They are connected to the vehicle’s brakes and engage automatically when the driver applies the brakes, providing additional safety.
• Electronic wheel chocks: These are high-tech wheel chocks that use sensors and electronic components to engage and disengage automatically. They are usually found in modern vehicles with advanced braking systems.

In addition to these types, other variations and designs exist, each suited for specific vehicles and situations. It is important to choose the right type and size of wheel chock for the vehicle and the parking conditions to ensure safety and effectiveness.

Specification & Maintenance of Automatic Wheel Chock
