电梯安全钳做为保障电梯安全的重要部件之一,其重要性是不言而喻的。安全钳的主要作用是:当电梯在故障状态下超速下滑或坠落而速度达到限速器动作速度时,由限速器操纵安全钳使电梯轿厢安全制停后夹持在导轨上,从而防止意外事故的发生。然而在实际使用中,却存在一些电梯轿厢未超速、限速器也未动作的时候安全钳动作的情况。这种非正常的安全钳动作会给电梯造成很大的维修困难,而且会直接增加维修成本,因此有必要对
Elevator safety gear as one of the important components to protect the safety of the elevator, its importance is self-evident. The main role of the safety gear is: When the elevator speeding in the fault state overshoot or fall and the speed reaches the speed limiter action, the safety gear by the speed limiter to make the elevator car stopped after the system security grip on the rail, thus preventing Accident happened. However, in actual use, there are some cases in which the elevator car does not speed up and the speed limiter does not move when the safety gear moves. This abnormal safety gear moves will cause great maintenance difficulties for the elevator, and will directly increase maintenance costs, it is necessary to
