Abstract

See full text

An elevator car has a brake system with braking devices engaging braking webs integrated into guide rails to brake the car. The braking devices include a brake housing, a first brake body movable by contact with the braking web and relative movement between the braking web and the brake housing to clamp the brake web, and a pusher arranged on the brake housing with the braking web arranged between the first brake body and the pusher with a required passage clearance. The pusher can be advanced toward the first brake body and pressed against the braking web to forcibly bring the first brake body into contact with the braking web. A pressing lever pivotally mounted on the brake housing acts to press the pusher against the braking web.
