Device (1) for carrying an object (2) having a smooth surface, which device comprises a first frame (3) that is arranged to be able to manipulate the device and the object to be carried, as well as a second frame (5) onto which a number of suction cups (6) is attached. The second frame is planar rotatably with respect to the first frame. Furthermore a number of vacuum sources (8, 9) is provided for evacuating the suction cups. The vacuum sources and suction cups are interconnected by means of at least one spiral-shaped hose assembly (10) of which the hoses (11), each being connected to a vacuum source (8) and a suction cup (6), are in the same spiral plane (14).

A portable vacuum lifter system having a power source, drive motor, vacuum pump and reservoir contained in a readily carriable case. The system also has a vacuum pad in fluid communication with the vacuum pump via a vacuum line and a solenoid operated valve. The system is removably mountable on a small host vehicle for use in confined areas.

Device for manipulating a flat object (1), comprising a lifting hook (2) and a traverse (4) with suction cups (5), which are evacuated by means of a vacuum pump (6). The traverse is connected to the hoisting hook via a bearing structure (7), so that the traverse can be rotated (R) and be tilted (K). The bearing structure comprises a rotary bearing (8/9) and a pivot bearing (11/13). The rotary bearing comprises an outer bearing member (8) connected with the traverse and an inner bearing member (9). The pivot bearing is connected with the lower end (12) of the lifting hook by means of a first bearing portion (11), and is connected to the inner bearing member of the rotary bearing by means a second bearing portion (13), which is tiltable relative to the first bearing portion. By means of a mounting frame (14) the vacuum pump is connected with the second bearing portion (13) of the pivot bearing and/or with the inner bearing member (9) of the rotary bearing, so that the vacuum pump tilts but does not co-rotate with the traverse and the object.

Systems, methods, and vacuum chucks for transferring flexible elongate bodies are disclosed herein. The vacuum chucks include an elongate rigid support, a vertically oriented vacuum surface, a vacuum manifold, and a skirt seal. The systems include an elongate horizontal support structure, a transfer structure, a plurality of vertical linkages, which are operatively attached to the elongate horizontal support structure, and a plurality of vacuum chucks. Each of the plurality of vacuum chucks is operatively attached to a respective one of the plurality of vertical linkages. The methods include suspending an elongate horizontal support structure with a transfer structure, aligning each of a plurality of vacuum chucks with a respective portion of a vertical surface of a flexible elongate body, selectively actuating each of the plurality of vacuum chucks to retain the respective portion of the vertical surface of the flexible elongate body, and lifting the flexible elongate body.

A system and method for moving objects such as drill, pipe with vacuum power. A vacuum beam (14) is mounted on a boom. A vacuum pad (12) is pivotally attached to the vacuum beam (14). A power device (18) is operatively connected to a vacuum pump (16) with a drive belt (32) for creating vacuum pressure. Vacuum pressure from the vacuum pad (12) is used to grasp and release the object, e.g., the drill pipe.

A vacuum lifter of this disclosure includes a spreader bar having a lifting lug at a top end and pad hanger locations at a bottom end; a pair of legs rotatably connected at a corresponding end of the spreader bar, each leg including a foot at a lower end of the leg; each leg having a first locking position in which the foot is below the spreader bar and a second locking position in which the foot is above the spreader bar; and a pair of vacuum pads adapted for connection to a vacuum source and to the pad hanger locations of the spreader bar. The spreader bar may be extendable. The vacuum source may be mounted on the spreader bar. The vacuum lifter is useful for lifting objects out of confined spaces below grade.
