Summary:A hoistway access system for an elevator includes an access switch positioned at a selected landing floor 34 of an elevator and operably connected to a controller 46. A remote controlled lock 48 is located at landing doors of a landing floor providing access to a hoistway pit 36, and is operably connected to the controller. A safety actuation system is operably connected to an elevator car and operably connected to the controller. The controller is configured to command a drive system to drive the elevator car to an upper location when the access switch is activated, to define a selected safety volume in the hoistway defined by the hoistway pit and the elevator car, command engagement of the safety actuation system to stop and hold the elevator car, and command the lock to unlock when the safety actuation system is engaged, thereby allowing access to the hoistway via the landing doors.
