Abstract
A braking system for a hoisted structure guided along a guide rail is provided. The braking system includes a brake member for coupling to the hoisted structure and having a brake surface configured to frictionally engage the guide rail, the brake member moveable between a braking position and a non-braking position. Further included is a brake member actuation mechanism operatively coupled to the brake member and configured to actuate the brake member from the non-braking position to the braking position, the brake member actuation mechanism remaining coupled to the brake member in the braking position to control the braking force applied on the hoisted structure by the frictional engagement between the guide rail and the brake member.
