Abstract
An elevator may include an elevator car, one or more hoisting ropes, a traction sheave, an overspeed governor, at least one safety gear, a locking mechanism, and guide rails. The car may be suspended by the one or more hoisting ropes. The traction sheave may move the car using the one or more hoisting ropes. The at least one safety gear and locking mechanism may be fitted in conjunction with the car. The overspeed governor may be configured to activate and release, via a linkage, the at least one safety gear during operation of the elevator. The locking mechanism may be configured to activate and release, by operatively acting on the linkage, the at least one safety gear during installation, maintenance, or installation and maintenance of the elevator. When activated, the at least one safety gear may engage one of the guide rails to lock the car in place.
