Abstract
A crane having at least one jib system, a sensor unit for detecting a deformation of the jib system transversely to a load plane, and to an activatable adjustment unit for influencing the deformation of the jib system transversely to the load plane.
Claims9
A crane, said crane comprising:
- a jib system;
- a sensor unit operable to detect a deformation of the jib system transverse to a load plane;
- and
- an activatable adjusting unit configured to influence the deformation of the jib system transverse to the load plane;
- wherein a regulating unit and/or a monitoring unit is provided, with said regulating unit being in signal communication with the sensor unit and with the adjusting unit and configured to influence the deformation of the jib system in a regulated manner transverse to the load plane, and with said monitoring unit being in signal communication with the sensor unit and operable to monitor the deformation of the jib system transverse to the load plane, and wherein the adjusting unit has a load application actuator, which is connected to a load application unit and the jib for directly displacing deflection rollers arranged on a head region of the jib.
