Abstract: An elevator parking brake, a method for operating an elevator parking brake, and a control device for an elevator parking brake are provided. The elevator parking brake includes a parking brake frame attachable to an elevator car, a brake pad configured to be brought in contact with a guide rail guiding the elevator car along an elevator shaft, and an actuating mechanism mounted on the parking brake frame, for bringing the brake pad in contact with the guide rail and retracting the brake pad from the guide rail. The actuating mechanism includes a motor, an actuating member and a conversion mechanism configured to convert a rotational movement of the motor into a linear movement of the actuating member. The actuating member brings the brake pad in contact with the guide rail and retracts the brake pad from the guide rail. The conversion mechanism includes a cam mechanism having a cam member driven to rotate by the rotational movement of the motor, wherein a driving profile of the cam member is in contact with the actuating member. The driving profile is configured to convert the rotational movement of the cam member into the linear movement of the actuating member.

Abstract: A rope terminal assembly of a hoisting apparatus includes a first compression member having a first contact face and a second compression member having a second contact face. The compression members are placed such that their contact faces face each other and delimit between them a gap. A belt-shaped rope having a thermoplastic polymer coating forming the outer surface of the rope is placed in the gap, the contact faces of the compression members compressing against opposite wide sides of the belt-shaped rope. One or both of the compression members includes on the contact face thereof, and/or in proximity of the contact face thereof, one or more indentations, each indentation forming a cavity in the compression member which is in open connection with the gap and arranged to be empty when the thermoplastic polymer coating of the rope compressed by the contact face is solid, and to receive via said open connection thermoplastic polymer coating of the rope flowing from the gap pushed by the compression when the thermoplastic polymer coating melts. An elevator is provided with the rope terminal assembly.
