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.
Claims19
A device for releasing an elevator brake, said device comprising:
- an actuator which generates a brake releasing force, said actuator being positioned on a landing away from the elevator brake so that, from a position near said actuator, movement of the hoisting ropes and/or traction sheave is viewable and an indication that the elevator car has arrived at a landing zone can be perceived from a position near the actuator;
- and
- a mechanical power transmission system for transmitting the brake controlling force from said actuator to a braking element.
A method for releasing a elevator brake, said method comprising the steps of:
- generating a brake releasing force when an operator activates an actuator, the actuator being positioned on a landing located away from the elevator brake, the actuator position allowing the operator to view the hoisting ropes and/or traction sheave and to perceive when the elevator car has arrived at a lading zone;
- and
- transmitting the generated brake releasing force from the actuator to a braking element.
