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.

Crane and method for influencing a deformation of a jib system of said crane

A crane includes an under carriage, an upper carriage, a rotary connection, by means of which the upper carriage is connected with the under carriage to rotate around an axis of rotation, a jib to be connected with the crane and erected around a jib axis, and a device connecting the upper carriage with the under carriage with at least one force-transmitting element. The at least one force-transmitting element is designed passively in such a way that it transmits forces between the upper carriage and the under carriage when a pre-determined load condition of the rotary connection is reached.

Crane, device and method for deflecting forces on a crane

A rotary connection for a work machine, such as a crane, includes a rotational axis, an inner bearing ring, an outer bearing ring and at least three bearing body ring arrangements arranged between the bearing rings with a plurality of respective bearing bodies. At least one of the bearing body ring arrangements is configured to at least partially withstand forces directed in the radial direction to the rotational axis. At least two of the bearing body ring arrangements are configured to at least partially withstand forces directed parallel to the rotational axis and are arranged adjacent to and spaced apart from one another along the rotational axis. The at least two bearing body ring arrangements are configured to at least partially withstand forces directed parallel to the rotational axis in each case establish a direction of action and are arranged spaced apart from one another along the direction of action.

A crane, in particular a large crane, including a power consumer system for providing energy, a primary energy source for feeding primary energy into the power consumer system, at least one secondary energy source, independent of the primary energy source, for feeding secondary energy into the power consumer system, at least one energy storage unit arranged locally on the crane and is, in particular, associated with the at least one crane component and connected to the power consumer system for storing primary energy and/or secondary energy, at least one drive motor connected to the power consumer system for operating at least one crane component and a secondary energy source configured such that energy returned from the crane operation is at least partially fed as secondary energy into the power consumer system. The at least one crane component is configured as a secondary energy source for energy recovery.

A boom () is used for receiving loads on the end thereof. The boom () has a metal boom hollow profile () extending along a boom longitudinal axis (), and also a reinforcing layer () made of a fiber-plastic composite, connected to the boom hollow profile () at least in sections. At least one sensor element () is arranged in the region of the reinforcing layer (). The sensor element () is used to detect strains in the boom ().
