Abstract
A crane, in particular a tower crane, with a boom rotatable about an upright slewing gear axis and an out-of-service brake which permits and slows down the rotary movements of the boom in the out-of-service condition. The out-of-service brake is formed to operate in a rotational-speed-dependent manner such that with a greater rotational speed of the crane the applied braking torque is greater than with a smaller rotational speed of the crane.
