摘　　要：安全钳作为电梯的重要安全保护装置,是增强电梯安全性的重要组成部分,对电梯的安全运行提供有效的保护。本文介绍了安全钳的工作原理及其作用,采用制停距离和平均减速度两项技术指标,通过对比试验研究导轨抗拉强度、载荷以及安全钳动作触发速度对安全钳制动性能的影响。试验结果表明,导轨抗拉强度过高,超载及触发速度过大都会使制停距离增大,从而降低安全钳的制动性能。Safety gear is an important elevator safety device and a necessary part to enhance safety of elevators, provides effective protection for the elevator safe operation. This paper introduces the working principle and the role of safety gear in elevator system, using the technical index of braking distance and average deceleration, researches the influences of rail tensile strength, load and trig speed on safety gear braking performance by contrast test. The research shows that rail tensile strength, overload and trig speed will increase braking-distance and reduce the safety gear braking performance.
