The OSL30 Series Overspeed Safety Lock(Fall arrester) is a specialized safety device mainly designed for suspended working platforms and similar lifting equipment. It adheres to the EN 1808 safety standard and relies on a centrifugal trigger mechanism to prevent falling accidents caused by overspeed descent, which is widely applied in construction and high-altitude operation scenarios. Here is a detailed breakdown of its relevant information:
Core Working Principles of Fall arrester
It is equipped with a centrifugal governor and a clamping jaw mechanism. The governor continuously monitors the descending speed of the equipment. When the descending speed of the wire rope exceeds the preset threshold, the centrifugal force triggers the clamping jaw mechanism. The jaw, made of hardened steel, can quickly grip the wire rope within a short distance, thus immediately stopping the equipment from falling and ensuring the safety of operators and the equipment itself.
