Abstract
A manually activated elevator braking release including an actuating element placed away from the brake and a mechanical power transmission system for transmitting releasing power from the actuator to a brake element. The actuator is placed on a landing and a window is provided near the actuator so that an operator can observe movement of the hoisting ropes and/or traction sheave. Arrival of the elevator car at one of the landing zones is indicated in a manner allowing it to be perceived from a position near the actuator.
