To make it possible to freely move a moving body between level surfaces located at different heights that are not connected by a vertical member. A moving body includes a movable moving part, an expansion/contraction part disposed in the moving part and configured to expand and contract in a vertical direction, a first engagement part disposed at a tip of the expansion/contraction part and configured to engage with a member located in a surrounding environment, and a control unit configured to control the moving part and the expansion/contraction part. The control unit moves the moving part to a target height position by engaging the first engagement part with a member located at the target height position and then expanding or contracting the expansion/contraction part.

Disclosed is a tracked lifting platform for vehicles (14), comprising at least two tracks (16), wherein each track (16) engages at least at a respective end region of a lifting platform (18) for lifting and lowering the track (16) between a basic position (19) and a working position (21), wherein the lifting platform (18) comprises a push column (21) with multiple push members (23), which can be arranged one above the other so as to be resistant to pressure in the vertical direction.

A robotic picking assembly (100) comprising an arm support arrangement (8) configured to move vertically and to rotate about a vertical axis. A horizontally extendable arm (1) is supported in the arm support arrangement. A gripping tool (20) arranged at a free end (1a) of the arm. The arm comprises arm modules (2) linked together in a chain. The arm modules (2) have a pivot means (4) linking adjacent arm modules together in a pivoting manner and a pivot restriction means (15, 16, 18, 19) limiting curving of the arm to only one direction. The arm support arrangement (8) has an arm guiding arrangement (25, 21, 21a, 21b, 33) guiding the arm between an extended position and a retracted position, and an arm drive arrangement (7) configured to move the arm between said extended and retracted positions.

An engagement chain has two chain members. Each of the chain members includes link plates, each of which has two pin holes, and coupling pins. The two pin holes are aligned in the advancing/retreating direction and are sized differently from each other. Each of the coupling pins of each chain member is tightly received in the smaller pin hole of the two pin holes of one of any adjacent two of the link plates in the advancing/retreating direction and is loosely received in the larger pin hole of the two pin holes of the other one of the two adjacent link plates. In a state in which the chain members are integrated with each other, any two of the coupling pins that are opposed to each other are in the same received states in the corresponding pin holes.

Provided is an interlocking chain-type forward and backward actuating device, the device being configured so that an increase in the number of parts is minimized, an increase in the size of the device is avoided, the amount of scattering of lubricating oil to the outside of the device is reduced, the wear of connection pins is reduced, the breakage of the connection pins is avoided, and the striking noise and vibration of the chains occurring during the reception of the chains are reduced. Chain guide plates are respectively provided on both sides of a pair of interlocking chains in the chain width direction. Chain locus restriction members having chain locus restriction faces in contact with rigid chain portions, which are made rigid by engaging and integrating the pair of interlocking chains with each other, are disposed so as to be adjacent to the rigid chain portions.
