Abstract

A device 2 for balancing the movable jib 3 of a crane structure comprises a linkage with a first 6, a second 7 and a third link 9 of which adjacent ends coverage to a common junction point 10, to which junction point 10 at least the first 6 and the second link 7 are rotatably connected, the end of the first link 6 which is remote from the junction point 10 being connected to one end of a balancing arm 4, the end of the second link 7 remote from the junction point 10 being connected at 8 to a tower of the crane structure, and the end of the third link 9 remote from the junction point being connected to the jib 3. <IMAGE>
