    Abstract: A fixing point arranged at a guide rail consists substantially of a slide, which is movable along the guide rail and which is guided by guide shoes at the free limb of the guide rail and carries a yoke. A bracket, at which a damping element is supported, is arranged at the guide rail. The end of a belt is held by a connecting element, which in turn is suspended by a tie rod and nuts at the yoke. In the case of an emergency stop situation in which the brake of the drive unit retards the elevator car to standstill, the retardation forces arising in that case are transmitted by belt, connecting element and tie rod to the yoke, wherein the retardation forces produce a displacement of the slide downwardly into the spring-stressed position against the damping capability of the damping element.

  • Patent number: 7946390
    Abstract: An elevator system (20) includes a tie-down compensation arrangement (40). A tension member (42) extends between a cab (22) and counterweight (26) to provide a desired amount of tension on a load bearing rope or belt (30) that supports the cab and the counterweight. The tension member (42) in one example comprises a coated steel belt. At least one sheave (46) is supported on a base module (48) and remains stationary relative to a floor of a pit (52). A damper (50) is supported for movement with the counterweight (26) or the cab (22) to absorb energy that would otherwise tend to cause counterweight jump following a rapid descent and stop of the cab (22).

  • Publication number: 20110042170
    Abstract: The present invention refers to a configuration of the pulleys and ropes so as to obtain the cage (21) suspension of the size ratio type at least equal to 1:2 or greater (1:4, 1:6, 1:8, etc) and the suspension of a balance weight (14) always equal to 1:2 in size ratio, formed such that the path of the balance weight is equal to the path of the cage. The ropes going from the traction pulley (2) towards the balance weight pass between the pulleys placed on the cage and the pulleys (5, 8) placed in the lower portion of the shaft, such that the portion of the size ratio not obtained between the balance weight and the upper portion of the shaft is realized between the cage and the lower portion of the shaft, so as to equalize on the whole the size ratio between the cage and the upper portion of the shaft. Advantageously, the invention can be provided with segmented dowelling of the pulley races and insertion undercut.

    Abstract: A cable fixing point for fastening at least one cable includes a cable end fastening for the cable end and a rotary mounting for the cable end fastening, wherein the rotary mounting enables rotation of the cable end fastening about an axis and the axis can be aligned by a tension force acting on the cable. In an elevator for transporting at least one load carrier by at least one cable movable in its longitudinal direction wherein the respective cable at the cable end is disposed under a tension force, the direction of which is variable in dependence on a position of the load carrier, this cable fixing point permits rotation of the cable at the cable fixing point about an axis which is aligned in the respective direction of the tension force and/or in the respective longitudinal direction of a cable segment adjoining the cable fixing point.

  • Patent number: 7647675
    Abstract: A suspension belt end connector has first and second wrapping elements that are arranged in a housing. The housing may have a back wall, side walls and an open side opposite to the back wall. The side walls taper and form with the back wall and a yoke a suspension unit to accommodate a suspension bolt. The end connector supports a poly V belt which serves as a suspension element. The belt is laid around the first wrapping element in a first loop, around the second wrapping element in a second loop, and again around the first wrapping element in a third loop that runs opposite to the first loop. The end of the belt is then held fast by means of a clamp or wedging device. Ribs of the first and third loops mutually engage, as a result of which the coefficient of friction in the engaged section of the belt is increased.
