Abstract:
An electromagnetic safety trigger 46 includes a link 72 kinematically connected to a safety 70A, 70B of an elevator system mass, such as an elevator car or counterweight. An electromagnet 76 mounted on a linear actuator 74 is magnetically coupled to the link 72, and a spring 78 is connected between the link 72 and the elevator mass. The electromagnet 76 can be triggered to release the link 72, which allows the spring 78 to move the link 72 to engage the safety 70A, 70B.
