What safety measure is used to secure the wheels of a scissor lift when parked?

Wheel chocks are a crucial safety measure used to secure the wheels of a scissor lift when it is parked. They are designed to prevent the lift from rolling or moving unexpectedly, especially on slopes or uneven surfaces. By placing wheel chocks behind the wheels, they create a physical barrier that enhances stability and ensures that the lift remains stationary while personnel are working at height.

In scenarios where lifts are parked on inclines, relying solely on other means, such as an emergency brake, may not provide sufficient safety. While such brakes are important for operating lifts, they do not replace the necessity for wheel chocks when parking. Ground anchors are more relevant for securing equipment in situations prone to tipping rather than for wheel stabilization on parked lifts. Similarly, stabilizing legs provide support and stability during operation but do not prevent movement of the wheels when the lift is not in use. Therefore, using wheel chocks forms an integral part of an effective safety protocol in managing scissor lift operations.
