Abstract: A safety locking device for a shaft door of an elevator and a method for opening the shaft door using the safety locking device involve a shaft door lock having: a first stopper stopping the shaft door at a closed first position wherein the lock locks the shaft door; an emergency release mechanism manually releasing the lock allowing movement in an opening direction; a second stopper stopping the shaft door at a semi-open second position between closed and open wherein the lock locks the shaft door; and at least one counter-stopper engaging with the first stopper to stop the shaft door at the first position and engaging with the second stopper to stop the shaft door at the second position.

Abstract: A mobile device and a method for monitoring an elevator system in a multi-level building use a mobile device having a screen for monitoring the elevator system. The elevator system includes an elevator car movable, under the control of an elevator controller of the elevator system, between the floors of the building in an elevator shaft. The mobile device is able to communicate continuously with the elevator system, in particular with the elevator controller or the elevator car, via the position data of the elevator car such that the current position of the elevator car in the elevator shaft with respect to the position of at least one floor of the building is displayed continuously on the screen of the mobile device.

Abstract: A modular drive for an elevator installation and a method of converting and fastening the drive in the elevator installation includes combining the main drive components such as a drive device, a brake device and a drive pulley into a drive module. Connecting parts for fastening the drive within an elevator shaft or in an engine space, or for adjusting a support means spacing, are mounted on the drive as required.

Abstract: Equipment for suspension of a car or a counterweight in an elevator installation and methods for mounting and for maintenance of the suspension apparatus includes deflecting roller units. The car or the counterweight hangs at support belts that are each connected with the car or the counterweight by an associated one of the deflecting roller units. Each roller unit provides space for one of the support belts. The roller unit provides compensation for different elongations of the several support belts and it enables simple mounting of the support belts.

Abstract: A modular drive for an elevator installation with a car and a counterweight includes a drive pulley driven by a motor and a self-supporting deflecting module with a deflecting roller, wherein the motor and the drive pulley are combined to form a self-supporting drive module. Interfaces for attachment of connecting parts are provided at the drive module or the deflecting module.

Abstract: A safety device brakes an elevator car with a guide rail exhibiting an oblong guide flange. The safety device includes a base carrying a retaining element and an abutment with the guide flange positioned therebetween. A mechanism squeezes, when braking, a braking element blocking roller between the guide flange and the abutment. The mechanism, co-operating with an electromagnet, moves the braking element in a controlled way between different positions associated with different operating conditions of the safety device.
