Apparatus for driving a self-propelled elevator |
摘要 |
A friction wheel drive apparatus for a self-propelled elevator car movable in an elevator shaft can be mounted on the top side or bottom side of the car. The drive apparatus is connected with a counterweight by a force transmission device for balancing the car weight and a portion of the conveyed load. The force transmission device is fastened to and guided at the drive apparatus such that a force generated by the counterweight, the weight of the car and the weight of the conveyed load is applied as a contact pressure to urge a friction wheel of the drive apparatus against a travel track surface.
