1前言限速器一安全钳系统是电梯必不可少的安全装置,该装置每时每刻都对电梯的安全运行起着极其重要的安全保护作用。当电梯超速,运行失控或悬挂装置断裂时,限速器一安全钳装置迅速将电梯轿厢制停在导轨上,并保持静止状态,从而避免发生人员伤亡及设备损坏事故。限速器在电梯生产过程中已进行型式试验,应能够满足性能要求,但是
1 Preface The governor-safety gear system is an indispensable safety device for elevators, which plays an extremely important safety protection role for the safe operation of elevators all the time. When the elevator speeding, running out of control or suspension device rupture, the speed limiter a safety gear device quickly stop the elevator car on the rail, and remain at rest, thus avoiding the occurrence of personal injury and equipment damage accident. Speed limiter has been type tested in the elevator production process, should be able to meet the performance requirements, but
