摘要: A crane comprises a base (1, 2), an articulated jib (3, 4) which is supported by the base, as well as hoisting means (5, 9) which are guided from the base via the jib, such as a hoisting cable. The jib comprises jib parts (3, 4) which are rotatably supported with respect to each other and with respect to the base (1, 2), as well as respective jib part drives (10- 12) for varying the angular position of jib parts with respect to the base or with respect to another jib part. One of the jib part drives has series-connected linear actuators (11, 12), one of which is connected to one of the jib parts and the other of which is connected to a jib part adjoining said jib part and which linear drives cooperate with each other via a guide (13) on the jib.
