Abstract

The crane has a crane support, and a hinge arm system (3) having a hub arm (4) and a break arm (5) connected with the arm (4). A hub cylinder is operated between the support and the hub arm, and a break cylinder (7) is operated between the arms. The hub arm has an accommodation section for the break arm in an area of articulation of the hub arm with the break arm, where the distance between the rotary axis of the articulation and a guiding point (11) of the break cylinder at the hub arm is larger than the distance between the axis of the articulation and guiding point (12) at the break arm.
