What Is a Wheel Chock?
A wheel chock is an item used, quite literally, to stop wheels in place, such as in parking spots or garages. It becomes necessary when the spot or garage is inclined, preventing the vehicle from moving on its own. Wheel chocks are not limited to cars; they also exist for railway vehicles and aircraft.
The size may vary, but they are typically around 50 cm in length, 13 cm in width, and 8 cm in height. They are wedge-shaped, and crafted from materials like wood or lightweight polyurethane.
In the context of aircraft, wheel chocks are also known as “chocks.” Therefore, the process of attaching wheel chocks to an aircraft is referred to as “chocking” or “chocking operation.” The individual responsible for choking is called a “chockman.” The chockman attaches wheel chocks when the aircraft arrives at the spot and removes them just before takeoff.
Uses of Wheel Chock
Wheel chocks are attached to wheels to prevent the unintentional movement of various vehicles, including aircraft, railways, and automobiles.
While some may feel it unnecessary, it can prevent major disasters in situations like brake failures or when the parking spot is inclined. It proves useful in these “what if” scenarios. Additionally, wheel chocks are effective during strong winds or adverse weather conditions.
However, it’s important to note that if wheel chocks are forcefully applied and jammed too tightly, they may become challenging to remove later, requiring caution in their use.
Furthermore, some engage in activities like reusing chocks and transforming them into charms for students praying for success in exams. This practice is symbolic, as the term “chock” implies anti-skidding, aligning with the wish for students not to “slip” during their exams.
