Abstract: A method for monitoring shaft doors of a elevator installation uses at least one contactlessly acting shaft door monitoring sensor to emit a beam of electromagnetic waves, wherein at least during specific detection phases the beam extends over several floors and is detected by a receiver. The beam is influenced by a shaft door panel not being completely closed and/or a shaft door lock not being disposed in the locking setting such that a disturbance signal is generated to the elevator control.

Abstract: An emergency drive is a toothed element such as a gear rim, is arranged on a traction sheave of an elevator drive. During emergency operation, the gear rim is driven by means of a pinion of an auxiliary engine. The engine is installed on the elevator drive only during an emergency operation. After emergency operation, the engine is removed from the drive unit. The gear rim may be composed of several layers of interlocked segments. The layers are mutually shifted in a circumferential direction. Each segment consists of laminated/interlocked sheet metal segments, which are, as mass-produced goods, cheaply producible through cutting and punching procedures.

Abstract: According to the invention, the maintenance scaffold (10) is assembled as follows: in a first step, an illuminated ceiling, which lies below the collapsed maintenance scaffold (10), is taken down. Suspension members (17) are then brought into a vertical position. The platform (12) and flap (13) are lowered vertically until they reach the bearings (19) of the suspension members (17). Before mounting the platform (12), the maintenance personnel must unfold the ladder (18) and open the flap (13) upwards. Once the personnel has mounted the platform (12), the flap is closed (13) by means of a handle, in such a way that the entire platform can be used as a working scaffold. With the maintenance scaffold (10) in the working position, the height for a regulatory passage (U) is maintained, as determined by the distance between the cabin ceiling (14) and the platform (12).

With the lift's safety brake dis-engaged and the lift drive unactuated, the drive brake is released and an additional force is applied to the lift cage from a source external to the lift drive to move the lift cage to a position for passenger evacuation. The additional force may be applied through a cable pull connected to the limiter cable of the elevator's speed monitor system.

Abstract: An apparatus and method for the emergency release of passengers who are trapped in an elevator car due to an operational disturbance includes a remote alarm device in the elevator car for summoning help from outside the building and equipment for the remote actuation from the elevator car of an electrical closing or locking system of a building outer door. Expert service personnel summoned from outside the building thus gain access to the elevator even when the building door is locked in order to release the trapped passengers. The actuation can be by a specific button installed in the car control panel or through input of a code or by a button combination of the control panel elements. According to a preferred embodiment, the remote unlocking is possible only temporarily, so as to prevent misuse of the emergency situation.
