The present disclosure relates to a method for the automatic telescoping of the boom system of a crane, in particular of a mobile crane, having at least one telescopic boom, and having a rope and a winch for pivoting the boom. The method comprises measuring an actual value of the boom angle of the boom and actuating, in particular automatically, the winch in dependence on the measured boom angle.

A conveyance system includes a robot and a suspending device. The robot moves and conveys a workpiece in a horizontal direction. The suspending device includes a suspending mechanism, a lifting unit, and a support mechanism. The suspending mechanism suspends the workpiece, and the lifting unit lifts up and down the workpiece. The support mechanism supports the suspending mechanism such that the suspending mechanism is movable in the horizontal direction.

A removable hoist assembly for lifting a load up and into a confined space in the form of a kit has a support structure releasably coupled to overhead structural beams in the confined space, a motor releasably coupled to the support structure above the support structure between the overhead structural beams, a hoist arm releasably coupled to the support structure to be rotatable and extendable with respect to the support structure, and a cable supported by the hoist arm. The cable has a free end positioned proximate a distal end of the hoist arm and configured to couple to the load and a terminal end coupled to the motor such that the cable extends and retracts with respect to the motor. The hoist arm support structure spreads the weight of the motor, hoist arm and the load across a plurality of the overhead structural beams.

Disclosed is a chuck disassembly and transfer device, which is composed of a telescopic cylinder, a cylinder support, a second linear guide rail, a second guide rail sliding seat, a lifting support, a chuck, a lifting chain, a lifting cylinder and the like, wherein the cylinder support and the second linear guide rail are fixed on the frame, the lifting support is connected with the second linear guide rail via the second guide rail sliding seat, and the telescopic cylinder is capable of driving the lifting support and the chuck to move horizontally along the second linear guide rail; the lifting cylinder is fixed on the lifting support, the chuck is connected with an output shaft of the lifting cylinder via the lifting chain, and the lifting cylinder is capable of driving the chuck to move vertically.

A telescopic handling device includes at least two elements (1, 2) mounted so as to slide relative to one another with interposition of sliding shoes (3, 4). The device includes thinner holding elements (5, 6) for the sliding shoes so as to limit the separation between two sliding elements to the thickness of the interposed sliding shoes (3, 4).

A transport system is for transporting an object back and forth between a storage area and a target area. The transport system has a pedestal for being placed at one of the storage area and the target area. The transport system has a main boom pivotably connected to the pedestal. The main boom has a far end configured for being supported by the other one of the storage area and the target area while allowing for at least one rotational degree of freedom between the main boom and the other one of the storage area and the target area. The main boom has a span that is passively adjustable in length. Furthermore, the transport system has a transport boom coupled with the main boom, and an object handler guided by the transport boom and configured for handling the object to be transported between the storage area and the target area.
