The invention relates to an in-ground lifting system and corresponding method for lifting a vehicle. The lifting system includes one or more lifts including at least one moveable lift; a support structure for mounting the one or more lifts in a pit; a moving drive configured for moving the one or more moveable lifts in the pit; a lifting drive configured for lifting one or more of the lifts for raising and/or lowering the vehicle; and a cover configured for covering the pit. The cover includes a number of cover elements. An individual cover element extends in a width direction of the pit. The cover elements are configured to move between a pit covering state and a lift moving state such that the one or more moveable lifts pass over and/or by the cover elements. The cover elements move when one of the one or more moveable lifts moving through the pit is approaching.

An improved system and method for bracing, transporting, assembling, and disassembly of drilling equipment at oil and gas land-based well sites. The system has a substructure with side boxes support bracing that are in a scissor jack (or grand plié) style bracing with telescoping tension link(s), linking pins, and vertical hydraulic cylinders. These linking pins are set after raising the substructure and secure the telescoping tension link, support arms, and support bracing in place to maintain the integrity of the substructure. Alternatively the system has a substructure with side boxes support bracing that are in a scissor jack (or grand plié) style bracing with screw jacks and a means of stabilization during substructure raising. The substructure bracing reduces the overall length, reduces the upper and lower box spans, and balances the raising loads, subsequently lowering the transport weight of the side box such that a commercial walking system may be integrated into the side box and remain there during transport while maximizing the operating drill floor height while minimizing the transport height.

A bath tub lifter, comprising a seat element (1), a lifting apparatus (4) for raising and lowering the seat element (1) between a lower operating end position and an upper operating end position, and a scissor lift arrangement (10) having two pairs of scissor lifts with scissor elements, wherein, in the operative state, respectively two scissor elements are coupled to each other such that they are mutually pivotable about a bearing axis.

In some embodiments, a mobile robot unit for engaging a wheel of parked target vehicle is provided, the mobile robot unit comprising: a frame adjustable from a first configuration to a second configuration and vice versa, wherein in the second configuration the frame engages the vehicle wheel to apply a sufficient counterforce onto the vehicle wheel to lift the vehicle wheel and the vehicle weight supported by the vehicle wheel from the ground; and at least two wheel assemblies supporting the frame above the ground, each wheel assembly comprising at least one steerable wheel, the steerable wheel contacting the ground.

A centering device for determining a position of a vehicle includes free roller parts configured to respectively seat left and right vehicle wheels of the vehicle. A driving body pushes the vehicle wheels when the vehicle is seated on the free roller parts. The centering device may be simply and rapidly installed on a floor with a minimal height. Thus, complicated construction is avoided. The centering device also has a plurality of sensors and a sensor cleaner on a first plate and a second plate. The first and second plates are driven at the same time, in opposite directions to center the vehicle.

In the context of service and maintenance of heavy road vehicles, apparatus is provided that is configured to engage and support a rack and manoeuvre it into position relative to the vehicle to facilitate removal and installation of the wheels. The rack has a frame with a base and a pair of arms, each arm being pivotally attached to opposite sides of the base to pivot between an open configuration and a folded configuration. The apparatus may be expanded and contracted between an expanded configuration, where the rack engagement assembly is configured to engage the rack in the open configuration, and a contracted configuration where the rack engagement assembly is configured to engage the rack in the folded configuration.

Disclosed are a movable battery replacing platform (103) and a quick replacing system (100), wherein the movable battery replacing platform (103) comprises: a travel-driving portion (106) used for driving the movable battery replacing platform (103) to move on the ground; a lifting portion (107) mounted on the travel-driving portion (106), for lifting a battery during the replacement of the battery; and a battery mounting portion (108) mounted on the top of the lifting portion (107), for placing a battery to be replaced or a replaced battery, wherein the battery mounting porting (108) is provided with a battery replacing device. The device can use an unlocking device (50) to unlock a battery locked on the bottom of an electric vehicle, automatically aligning an unlocking point of a battery locking mechanism and realizing automatic unlocking in the movement. The whole process is fully automated without manual intervention and can improve battery replacement efficiency. In addition, the angle of an upper board (10) relative to the battery unlocking position can be adjusted by a movement actuating device, so that the unlocking point of the battery can automatically fit where the movable battery replacing platform (103) remains still, so as to further improve unlocking efficiency.

A loading apparatus, in particular for conveying freight over a road surface and loading it into a transporting vehicle and unloading it therefrom, comprises a basic structure, a loading structure, with a freight holder, and a double-action lifting device between the basic structure and the loading structure. The loading structure here comprises a lifting frame, on which the lifting device acts, and a freight carrier, which is mounted on the lifting frame, via a pull-out guide with a pull-out direction oriented transversely to the lifting direction, and has the freight holder. An undercarriage serving for advancing the loading apparatus over the road surface is part of the freight carrier.

A shoe tying support assembly includes a frame that is positionable on a floor. A scissor lift is movably coupled to the frame and the scissor lift is actuatable between a lifted position and a lowered position. A platform is positioned on the scissor lift and the platform is spaced upwardly from the frame when the scissor lift is actuated into the lifted position. Thus, a user can position their foot on the platform for assisting with tying shoes. A tilting unit is coupled between the scissor lift and the platform and the tilting unit tilts the platform at a selectable angle of deflection from a horizontal plane to enhance comfort for the user to position the user's foot on the platform. A remote control is provided to remotely control the scissor lift and the tilting unit.

An apparatus for repositioning a piano between a horizontal orientation and a vertical orientation, and for moving the piano along a surface while in the vertical orientation. The apparatus comprises a base assembly, a cradle assembly, and a repositioning assembly. The base assembly provides a framework for connecting the cradle assembly to the repositioning assembly. The cradle assembly engages and supports the piano. The repositioning assembly moves the cradle assembly between a horizontal and a vertical position.
