ABSTRACT:
A guide apparatus for guiding and arresting an elevator running on column-like guides automatically prevents a transmission of guide alignment errors to the car and an unintended engagement of the arresting device. A roller carrier for engaging the guide running surfaces is rotationally movably mounted on the car with a center of rotation at the longitudinal axis of the guide so that the roller carrier can follow a twist of the guide about its axis. The roller carrier also mounts an arresting device which is vertically displaceable in a mounting bracket by contact with a buffer on an abutment attached to the elevator car. In the case of an arresting braking of the car, no force is transmitted to the guide apparatus.
