  • Patent number: 11753282
    Abstract: A jib system for a vehicle crane having a telescopic jib and a bracing apparatus that can be coupled to the jib by its base frame, where the jib has a roller head and a lifting cable that is deflected via the roller head. Only minor structural measures and preparations are required for automatically rigging and de-rigging the vehicle crane, including by providing at least one transfer rocker that can be integrated in an articulated manner between the jib and the bracing apparatus. By the pivotable support of the transfer rocker on the jib, the base frame configured for coupling to the lifting cable can be displaced by a change in the length of the lifting cable that is effected in the coupled state on a circular path around its roller head from a set-down position of the bracing apparatus to a set-up position of the bracing apparatus and back.

  • Patent number: 11685639
    Abstract: A device for moving an object is disclosed. The device has a drive cylinder with drive grooves and a set of idler pulleys. The idler pulleys are on a shaft that is parallel to the drive cylinder. Each of the idler pulleys rotate at an angle around the drive shaft that aligns the grooves of the idler pulleys to neighboring drive grooves. This allows the line to pass onto the drive groove, around an idler pulley, and onto a next adjacent drive groove. The line therefore winds back and forth between the drive grooves, the idler pulleys, and back to the next drive groove. One end of the line is placed under tension and the other is attached to an object or to a fixed member. The drive cylinder is driven and the line is moved through the device, or the device is moved along the line, respectively.

  • Patent number: 11660238
    Abstract: Provided herein is a electronically-controlled wheelchair securement system with a winch apparatus that is adapted for pulling and steering a mobility device (e.g., wheelchair, scooter, stretcher, etc.) up and down the ramp of a rear-entry wheelchair accessible vehicle and for providing securement for the mobility device during transport. The system includes two motorized front tie-down units adapted to be positioned in the vehicle at the front of the wheelchair securement area. The front tie-down units have extendable/retractable restraints adapted to connect to the front corners of the mobility device frame. By varying the motor speed between the two front tie-down units, the mobility device can be steered up the ramp. For example, when pulling the mobility device up the ramp, the mobility device can be directed to the left by increasing the speed of the right tie-down unit, slowing the speed of the left tie-down unit, or both.
