  • Publication number: 20130168622
    Abstract: A control system for a lifting device and a lifting device comprising the same are disclosed. The control system includes a control unit comprising a processor with a memory communicatively coupled to the processor and having computer readable and executable instructions. A battery is electrically coupled to the control unit in addition to at least one indicator. The processor executes the computer readable and executable instructions to: determine an operating characteristic of the lifting device and an operating time of the lifting device as the lifting device is actuated; determine an accumulated load-time parameter for the lifting device based on the operating characteristic and the operating time; store the accumulated load-time parameter in the memory of the lift control system; compare the accumulated load-time parameter to a service constant; and provide an indication the indicator that a lift structural component requires service based on the comparison.

  • Patent number: 8240437
    Abstract: A brake system for a rollator may include a brake handle, a braking device operatively coupled to the brake handle, and a gear rim mechanically coupled to at least one wheel of the rollator. The brake handle may be pivotally attached to a frame of the rollator and comprises a service-brake position and a parking-brake position while the braking device may be disposed on the frame of the rollator proximate the at least one wheel. When the brake handle is in a service-brake position, a braking member of the braking device is frictionally engaged with an inner portion of a rim of the at least one wheel thereby braking the wheel. When the handle is in a parking-brake position, the braking member of the braking device is engaged with teeth of the gear rim thereby preventing the wheel from rotating.

  • Patent number: 7976086
    Abstract: A safety locking device for a lifting hook comprising a lifting part and a hook part having a first and a second shank arranged in the same plane, the first shank being attached to the lifting part. The safety-locking device is pivotably attached to either of the shanks or the lifting part and comprises a spring means formed integrally with the safety locking device, one end of which is attached to the safety locking device diametrically opposed its fastening point to either shank or the lifting part and the other end is arranged to bear on the opposite shank or the lifting part, to which the safety locking device is pivotably attached to automatically bring the safety locking device to bear on the lifting part or the opposite shank so as to prevent unhooking of a hoisting cable or similar means introduced into the hook part.

  • Patent number: 7647655
    Abstract: A support frame assembly for attachment to a support mast of a transport apparatus may include a support frame with a pair of downwardly directed mounting posts. Support arms may be pivotally attached to an end of each mounting post. The support arms may each comprise a back support and an open position and a closed position. When the support arms are in the closed positioned the back supports may be substantially horizontally oriented defining a support area between the support arms, the back supports and the support frame. When the support arms are in the open position the back supports may be substantially vertically oriented and the support area is open opposite the support frame.

  • Patent number: 7604219
    Abstract: Patient lift systems having a telescoping lifting apparatus include a telescopically displaceable lifting beam and a fixed lifting beam. The telescopically displaceable lifting beam may be operable to extend out from the fixed lifting beam to a protruded position. A casing may be brought to surround both the telescopically displaceable lifting beam and the fixed lifting beam and extend a certain distance over both the telescopically displaceable lifting beam and the fixed lifting beam when the telescopically displaceable lifting beam is in the protruded position. A pressure spring may be situated within the casing between a top end of the casing, which may surround the telescopically displaceable lifting beam, and a spring support, which may attach to the fixed lifting beam.

  • Patent number: 7165908
    Abstract: Two telescopic lifting beams are loaded in their protruded position and are driven from a retracted position to a protruded position. In order to improve the bending strength of the lifting beams, the lifting beams are surrounded by two telescopic tubes, one of the tubes being fixed to the outer end of the telescopic first lifting beam and is slideable on the second telescopic tube, which extends inwardly on the second lifting beam.

  • Patent number: 6892403
    Abstract: Hoisting harness for persons, where the lifting action takes place by a harness consisting of a seat-piece placed between the person's legs, to which seat-piece a rear-piece is connected, which runs against the person's back and further consists of a front piece which runs against the chest. The front-piece and the rear-piece in their free ends have loops to be applied to a lift hanger. In order to avoid that the harness shall not be too tight across the chest during the lifting action and that the harness is adaptable to the size of the person's body, the front-piece and the rear-piece are connected by two connecting bands each band passing one side of the body, whereby the length of the connecting bands between the front-piece and the rear-piece is adjustable.

  • Patent number: 6581222
    Abstract: A harness for lifting a disabled person from a sitting position to a standing position by a lifting device having two attaching points for the lifting action, there being a distance between these points. The harness including a belt at least partly surrounding the body of the person to be lifted, which belt has four bands, which can be hooked on the attaching points so that the belt surrounds the person overlapping on the breast under breast height and two of the bands crossing each other. In order to increase the lateral stability when lifting the person two other of the four bands are attached to a back piece forming a part of the harness, which back piece is extended at the rear of the back of the person and outside the shoulders.

  • Patent number: 6568002
    Abstract: Aid apparatus for raising a disabled person from a sitting position to a standing position, which apparatus includes a wheeled base in the form of a U-formed frame having a post, which supports a lifting device. The lifting device includes a lifting arm arrangement having a free end, which can be raised and lowered in relation to the base and supports the lifting sling. The aid apparatus may turn over if the person leans at one side in a standing position and a fork-shaped lateral support is therefore arranged, the open end of which opens in the direction from the post and surrounds the upper part of the body when the person is in the standing position. The breadth of the fork-shaped lateral support corresponds to the person's breadth and is not larger than the breadth of the U-formed base. The fork-shaped lateral support being arranged not swingable in relation to an axis, which is perpendicular to the plane of the U-formed base.
