An under hoist support stand in which the spin handle to turn the threaded support screw can be selectively engaged and disengaged from the support screw and allows the screw to be positioned along a longitudinal axis of the support stand.

A parking robot includes a lifting rail, a wheel clamp, and a lift motor. The wheel clamp is disposed on the lifting rail and is moveable from a first position to a second position along the lifting rail. The lift motor is operatively connected to the lifting rail and moves the wheel clamp from the first position to the second position.

A range hood support lift for positioning and supporting the weight of range hoods, exhaust vents, microwave ovens, and the like during the installation process. The range hood support lift includes a support section having a plurality of support arms. A base section includes a plurality of legs and a scissor section separates the plurality of legs. In use, the base section adjusts the height of the support section above the base section and the scissor section adjusts the distance between the plurality of legs.

A lifting jack system includes a lifting bar; having a track of teeth running vertical along one edge of the lifting bar; and a foot secured to a base of the lifting bar; a lifting head secured around the lifting bar and vertically moveable along the track of teeth; a nose, extending outward from the lifting head for securing to an item to be raised; a gear system housed within the lifting head, the gear system having a safety gear with asymmetrical teeth; a spring loaded pawl engaged with the teeth of the safety gear; and a round gear with symmetrical teeth engaged with the teeth of the safety gear and the track of teeth of the lifting bar; and a ratchet bar secured by a ratchet to the safety gear and extending outwardly from the lifting head; the ratchet bar is to turn the safety gear via the ratchet, thereby engaging the safety gear with the round gear, the round gear then engaging with the track of teeth to raise the lifting head along the track of teeth; and the spring loaded pawl engages with the safety gear to prevent downward movement of the lifting head.

The present invention provides a furniture jack that can be self-locking, labor-saving and easily portable, including: the bottom plate, the bottom plate is fixed with a straight bar, the moving plate is provided on the bottom side of the bottom plate, the top of the moving plate is fixed with a shell, the internal rotation of the shell is connected with a worm. The invention provides a self-locking, labor-saving, convenient to carry, the furniture jack, driven by turning the grip of the handle and the worm, make a lever between the handle and the worm, operation, and screw mechanical structure, without relative sliding, can be stable for large objects, to increase security, and after the end of the use, to receive the grip, reduce the space to carry, improve the user experience.

A lifting apparatus and controller therefore, where the lifting apparatus includes independently driven lifting columns and independently driven wheels that are controlled by a controller having a number of sensors such as limit sensors, position sensors, rotation sensors, laser sensors, torque sensors and the like. The independent motors for lifting and driving may also be removed easily to provide for improved servicing and maintenance. The various sensor signals are used to calculate, coordinate and calibrate the apparatus for precise and safe movement by the motors in order to perform lifting and positioning operations, for example rail car repair and service.
