  • Elevator lift cage load measuring assembly
    Patent number: 7784589
    Abstract: Load measuring equipment has a small-area load sensor arranged between a support and a first damping body for vibration damping of parts relative to the support. The support may be a bracket and the parts may be a lift drive engine. The force on the sensor, which may be the force emanating from an engine foot of the drive engine made up of cage weight, cage load, weight of the counterweight, weight of the support cables and weight of the drive unit, is a small portion of the force on the support, such as the bracket. The ratio of the area of the first damping body to the load sensor determines the ratio of the force acting on the damping body to the force acting on L, and sensed by Z the load sensor.

  • Method of operating an elevator installation, an elevator installation operable by this method and safety equipment for this elevator installation
    Patent number: 7779967
    Abstract: An elevator installation with at least one upper elevator car and at least one lower elevator car includes a first electromechanical switching mechanism mounted on the upper car and having a weight fastened at a downwardly extending elongate run, the run being held in a travel setting by the weight force, and a second electromechanical switching mechanism mounted on the lower car vertically below the weight. In the case of undesired approach of the two elevator cars, the weight impinges on the second electromechanical switching mechanism and thereby opens a safety circuit of the lower elevator car. The safety circuit of the upper elevator car is also opened by a diminishing of the weight force.

  • Method and detection system for monitoring the speed of an elevator car
    Patent number: 7775329
    Abstract: A method and detection system monitors the speed of an elevator car and, in case of excess speed caused by brake failure of a motor brake or shaft fracture of a drive pulley shaft, a safety circuit is opened and the detection system is transferred from a normal operational state (State 1) to a retardation state (State 2) in which it is monitored whether the elevator car is retarded after defined speed presets. After a successful retardation, the detection system is transferred to a state of standstill monitoring (State 3) in which it is monitored whether the elevator car leaves its standstill position. If the presets of State 2 or State 3 are not fulfilled, the detection system is transferred to a braking state of the brake (State 4) in which a brake which fixes the elevator car is activated.

  • Synthetic fiber cable and elevator installation with such a synthetic fiber cable
    Patent number: 7757472
    Abstract: A synthetic fiber cable has the strands of a strand layer mutually spaced apart. With the mutual spacing, the strands of the outer strand layer can move radially in the direction of the cable center and exert a radial pressure on the strands of the first inner strand layer. The radial pressure is passed on from the strands of the first inner strand layer to the strands of the second inner strand layer. The radial pressure is passed on from the strands of the second inner strand layer to the core strand. The radial pressure increases inwardly from strand layer to strand layer. The soft cable sheathing does not act as a support between the strands in circumferential direction.
