In some embodiments, a system and/or method a may include a helicopter transport system. The helicopter transport system may include a support frame. The support frame may be substantially rectangular. The helicopter transport system may include a first pair of wheels. In some embodiments, the first pair of wheels may be positioned on opposing sides of the outer perimeter of the support frame towards a first end of the support frame. The helicopter transport system may include a second pair of wheels. The second pair of wheels may be positioned adjacent one another within the perimeter of the support frame towards a second end of the support frame. The first end of the support frame may be positioned opposite the second end of the support frame. The helicopter transport system may include a lift mechanism coupled to the support frame. The lift mechanism may elevate, during use, a helicopter above the support frame.

A robotic under surface loader includes a mobility platform, a parallel manipulator, and a cradle. The mobility platform enables the robotic under surface loader to be moved into place beneath a downwardly facing surface to which a payload is to be attached. The parallel manipulator, which is carried by the mobility platform, carries the cradle, which may in turn carry a payload. The parallel manipulator may position the cradle in six degrees-of-freedom and, thus, precisely position a payload carried by the cradle in a location and an orientation that will facilitate its interaction with (e.g., attachment to, etc.) the downwardly facing surface. Methods for attaching objects, including large, heaving objects, to downwardly facing surfaces are also disclosed.

A lift-truck including a support means extending from a load engagement means; a distance sensor to measure the distance (D) to the load engagement means; a control unit connected to an operator interface and a lifting/lowering unit and to the distance sensor, the distance sensor attached to the support means at a fixed distance above the load engagement means, the control unit receives start signal from the operator interface and performs a height adjustment cycle of the load engagement means comprising; determining a default distance (D.sub.0) to the surface on the load engagement means; determining the present distance (D) to the surface on the load engagement means; comparing the default distance (D.sub.0) and the present distance (D); moving the load engagement means a distance (R) when a difference (D.sub.delta) between the default distance (D.sub.0) and the present distance (D) is determined, the distance (R) depends on the difference (D.sub.delta).

An apparatus for conveying delivered items into a building envelope translocates deliveries from a designated receiving area exterior to a building envelope via secure passage onto a deposit area locatable interior to the building envelope. Deposit of an item upon the receiving area signals presence of the delivery. The apparatus is operable automatically via command instantiated in circuit and/or over network in response to the signal.

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.

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.
