What are helicopter wheel chocks?
Helicopter wheel chocks are devices used to secure helicopters during parking and ground operations. They are positioned against the helicopter wheels to prevent unintended movement while the aircraft is stationary. Helicopter chocks provide mechanical restraint and contribute to safe handling in aviation environments.
Where are helicopter chocks used?
Helicopter chocks are used in hangars, on helipads and in maintenance areas where helicopters are parked or serviced. They are applied during routine inspections, refuelling, loading and other ground handling procedures. Stable positioning is essential to ensure safe working conditions on concrete, asphalt or other prepared surfaces.
Design and load characteristics
Wheel chocks for helicopters are typically designed to match the wheel size and load distribution of helicopter landing gear. Compared to general vehicle wheel chocks, helicopter chocks may be dimensioned differently to ensure proper contact and load support under aviation-specific conditions.
Material and durability
Helicopter wheel chocks are commonly manufactured from rubber or other high-friction materials that provide stable contact between the tyre and the ground surface. The material selection influences wear resistance, grip and durability under repeated use in outdoor environments.
Application considerations
Selecting the correct helicopter chocks depends on helicopter type, wheel diameter and operational environment. Proper sizing and material choice help ensure consistent performance during ground operations.
