▶ Product Introduction

Construction elevators, also known as construction hoists, are commonly used on construction sites to transport workers, tools, and materials vertically.The primary purpose of an anti-fall device in a construction elevator is to enhance safety by preventing or minimizing the risk of a free fall in the event of a mechanical failure or loss of control.


▶ Product Advantage

1. Safety anti-fall devices are designed to engage automatically when specific conditions are met, such as an unexpected increase in speed or a loss of control. This rapid engagement is crucial for preventing or minimizing the fall.

2. The device typically incorporates an emergency braking system that acts quickly to bring the moving platform to a stop in the event of a fall. The braking system helps reduce the impact force and prevent a free fall.

3. Anti-fall devices are constructed from durable materials capable of withstanding the rigors of the operational environment. This durability ensures the long-term reliability of the device.


▶ Product Uses

Safety anti-fall device is suitable for construction elevator.
