  • Patent number: 7775325
    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.
    Type: Grant

  • Patent number: 7665580
    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.

  • Patent number: 7624847
    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.

  • Patent number: 7398863
    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.
