Abstract: The invention relates to a chain link for a handling chain and to the handling chain. The handling chain has a body consisting of a plurality of chain links, which adjoin each other in the longitudinal direction of the handling chain, wherein the chain links are connected to each other in the adjoining connection regions thereof in such a way that, in each case, the chain links can be pivoted about a first pivot axis extending in the transverse direction. The chain link is designed to form a hinge-joint connection with the joint partner, wherein the chain link has at least one connection region designed as a first connection region, said connection region being designed in such a way that the hinge-joint connection enables at least one further relative motion of the joint partners in addition to the pivoting about the first pivot axis.

Abstract: The invention concerns line guide devices, for example energy guide chains (31, 51), having a movement sensor. An aspect concerns a movement sensor (10; 20) including a bearing having a first component, for example a guide (11; 21) of a linear bearing, and a second component moveable relative thereto, for example a longitudinally displaceable slider (12; 22), and at least one pick-up (13, 14; 23, 24) whose output signal depends on the relative position of both components. The movement sensor (10; 20) can be arranged with the first component at the connecting location to be supplied and with the second component at the moveable end of the line guide device, or vice-versa. A further aspect concerns an apparatus (30; 40) for winding up and unwinding a line guide device. A rotatable drum (32; 42) for winding up and unwinding the line guide device has a drum drive (38; 48). A sensor unit (35; 45) is arranged at the load-side end region (52B) of the line guide device, for detecting a movement parameter.

Abstract: The invention relates to a transverse web for connecting two side parts of an element of a line guiding device, comprising a toggle lever closure (2) having an actuating part (3) and a locking part (4), wherein the actuating part (3) can be swiveled from the locking position completely to the unlocking position in one step by means of a tool (B), and wherein in an engagement area (10) at a distance to the free end (8) of the actuating part (3) and to the swivel axis (axes), a lateral recess (11) for engaging the tool (W) in the transverse web (1) and for applying a force by means of the tool (W) with at least one force component in the direction of the swivel motion of the actuating part (3) to the unlocking position thereof is provided, wherein the recess (11) is laterally delimited by the opening edge (12) of the opening (9) and the actuating part (3).
