  • Patent number: 11084689
    Abstract: A braking device may include first and second brake pads disposed opposite one another about a guide rail, for developing braking forces when the brake pads engage the guide rail. The first brake pad has a wedge shape and may taper in a wedge direction. A front side of the first brake pad facing the guide rail is aligned parallel to the guide rail, and a rear side of the first brake pad is angled corresponding to the wedge shape. The rear side of the first brake pad lies in a sliding manner against a contact surface of a first brake pad seat disposed at an angle corresponding to the first brake pad. In a first setting a locking device unblocks a sliding movement of the first brake pad, and in a second setting the locking device blocks the sliding movement of the first brake pad.

  • Patent number: 8851238
    Abstract: Apparatus for raising and lowering objects. In accordance with some embodiments, a winch motor is adapted to rotate a winch member in opposing first and second directions to wrap/unwrap a portion of a cable on/from the winch member to raise and lower a lifting platform assembly, respectively. A tension detection switch assembly includes an on/off switch connected to the winch motor and a biasing member which exerts a bias force upon the winch member to nominally deflect the winch member to a first position which sets the switch to deactivate the winch motor in an absence of tension in the cable from the lifting platform assembly. A presence of tension in the cable from the lifting platform assembly deflects the winch member to a second position which sets the switch to facilitate activation of the winch motor.

  • Patent number: 8381879
    Abstract: A drive system for use with a cable and a carrier for raising and lowering a payload includes a reel, a drive mechanism, a cable slack control mechanism, and a tension adjustment system. The drive member is operatively connected to the reel to rotate the reel in a winding direction when the drive member is rotated in a raising direction, and to controllably rotate the reel and/or permit the reel to rotate in an unwinding direction when the drive member is rotated in a lowering direction. The cable slack control mechanism is operative to automatically selectively decouple the drive member from the reel while the drive motor is rotating the drive member in the lowering direction when a tension on the cable does not exceed a threshold tension and/or the cable is fully unwound from the reel. The tension adjustment system is operable to selectively adjust the threshold tension.

  • Publication number: 20120279805
    Abstract: The invention concerns a lift having a drive unit. The invention further concerns a wind power installation having a lift. To reduce the costs of the lift and thus make the lift economically more attractive the lift of the kind set forth in this specification is characterized by a cupboard used as the lift car. In that respect the invention is based on the realization that a cupboard in its basic structure with bottom, side walls and a door does not differ from a lift car produced specifically for a lift. Naturally there are differences, for example in suspension and operation of the door, but those differences can be removed insofar as they are an obstacle to use of a cupboard as a lift car so that the complication and expenditure overall is always still less than the complication and expenditure for a lift car constructed specifically for the lift.

    Abstract: A lift system is coupled between a work platform and a mast on a mast lift. The lift system includes at least one lifting rope connected between the work platform and the mast via an idler roller and a hoist drum connected to the work platform. The idler roller is displaceable between an engaged position and a disengaged position based on an amount of tension on the lifting rope. A spring is connected to the idler roller and urges the idler roller toward the engaged position. A carriage latch assembly includes a carriage latch hook coupled with the idler roller and a pin secured to the mast. When the idler roller is disposed in the engaged position, the carriage latch hook is engageable with the pin.

  • Publication number: 20120132486
    Abstract: An emergency escape device for elevators is revealed. The emergency escape device is disposed in an elevator system. The emergency escape device includes a motor having an output end linked to a reduction gear set. An inner gear of the reduction gear set is engaged with a gear of a rope winder around which a steel cable is wound. Thereby the motor is released automatically from braking when the elevator system loses power and stops due to power outage or mechanical failure. Thus an elevator cabin is pulled downward by gravity and the rope winder rotates to unwind the wound steel cable. The steel cable goes down slowly so that the elevator cabin can goes down and stop at the nearest floor, allowing people trapped to come out.

  • Patent number: 7575098
    Abstract: A lift system and method for lifting or lowering items from one level to another within a building is accomplished by providing a lift platform. An upper level support structure having an opening is configured to allow passage of the platform through the opening. The opening is suspended above a generally open area of a lower level. An upper level frame is coupled to the support structure. A winch having a motor that rotates a drum is supported by the upper level frame. A length of cable secures at one end to the winch and at the other end to the platform through a biasing member. Operation of the winch rotates the drum to wind or unwind the cable to raise or lower the platform through the open area of the lower level without any laterally adjacent support or guidance structure within the open area.
