An elevator car includes an elevator car floor, a plurality of side walls, and a ceiling defining an interior of the elevator car. A ceiling panel access system includes a drum sheave arranged within one of the side walls, at least one locking pin arranged on a top of the elevator car and configured to releasably engage with a ceiling access panel to lock the ceiling access panel in a locked state and disengage therefrom to cause the ceiling access panel to open into the interior of the elevator car, and at least one cable operably connecting the drum sheave to the at least one locking pin, wherein rotation of the drum sheave causes the at least one cable to wind about the drum sheave and cause retraction of the at least one locking pin from engagement with the ceiling access panel.

Elevator car ceiling access system

A frictionless electronic safety actuator () for use in an elevator system, which includes at least one electromagnet (), and a magnetic plate () attached to a connection arrangement (). The connection arrangement () is configured to connect the magnetic plate () to a linkage () that is actuatable so as to move a safety brake () into frictional engagement with an elevator guide rail (). The at least one electromagnet () is operable to selectively produce a magnetic force which acts upon the magnetic plate () to displace the magnetic plate () and thereby move the connection arrangement () to actuate the linkage () without the magnetic plate () coming into frictional engagement with the elevator guide rail ().
