The invention relates to a crane, in particular a rotary tower crane, having drive devices (9-15) for crane and/or load movements in/around multiple movement axes, and having a crane control system (16) for driving the drive devices, wherein the crane control system has a monitoring device (17) for monitoring the crane loading and restricting crane movements when load limits are reached. The monitoring device has at least two load limits (LM1, LM2, LM3), between which the drive devices can only be actuated individually. |
