  • Patent number: 7237765
    Abstract: Speed limiter system to detect over speed and generate a signal to cut the power and if necessary operate brakes. It consist of the limiter itself, with a tension pulley. The limiter consists of weights connected by a mechanism that moves asymmetrically and by centrifugal force when an over speed occurs to operate the lever of an electrical contact, with the possibility of remote resetting using the necessary means. On the other hand, the tension pulley provides sufficient tension to both sections of the cable via an adjustable compression spring or by means of weights suspended on an articulated arm, both transmitting sufficient tension to the tension pulley axle.

  • Patent number: 7131517
    Abstract: A bi-directional safety mechanism used in an elevator safety device and which produces a gradual catch on a guide rail. The bi-directional safety device has a roller and two hinged rectangular frames, each having a friction element. One hinged rectangular frame is disposed above the roller and the other hinged rectangular frame is disposed below the roller with both hinged rectangular frames on the same side of the guide rail. In addition, a set of fixed brakes are disposed on the other side of the guide rail and opposite to the hinged rectangular frames, preventing this system from marking the guide rail during the braking process.
