ABSTRACT:
The invention relates to a link chain having two or more rows of chain elements, wherein the chain elements of one row are rotatably connected to those of the adjacent row in the chain plane in such a way that each chain element has two rotational axes, of which in each case one of the two rotational axes belongs to two different chain elements in adjacent rows, and that the chain elements of one row are connected to one another by means of toothed devices at their ends in such a way that the chain is flexible in the chain plane. The chain elements at one end of the link chain are likewise provided, at their outer side, with a toothed device, which is in engagement with an actuator. The actuator is a pneumatic actuator, a hydraulic actuator, an electromotive actuator or a manual drive actuator. The actuator may have a latching fitting, wherein the latching fitting is provided with a toothed surface that is in engagement with a toothed surface of a chain element in one row. The latching fitting may also be provided with a latching lug which is pivotably connected thereto and which can be locked in different angle positions. The latching fitting may also have a connection plate that has a toothed surface which is in engagement with a toothed surface of a chain element of the other row.
