There is provided a method for controlling a crane, with which the position of a hook is automatically adjusted before lift-off, where a freely-derricking telescopic boom is provided to a swivel base, a main hook is suspended with a main wire rope from a distal end section of the telescopic boom, and a suspended load is suspended on a main hook with slinging wire ropes, wherein post-slinging lift-off is preceded by a hook position adjustment control involving repeating: a first process where the control device controls so as to reel in the main wire rope to a position where the main wire rope is tensed; and a second process where the control device controls so as to move the distal end section of the telescopic boom in the same direction of a horizontal direction component of the movement of the main hook in the first process.

A computer-controlled mobile crane is disclosed herein, comprising a column which is rotatable around its vertical axis, a hydraulically actuated primary arm, a hydraulically actuated secondary arm, an attachment point to which a gripping assembly is attached. The components are actuated by a hydraulic control unit controlled by a computer control unit and corresponding software that generates an internal coordinate system on the basis sensors mounted on the crane and an optical measuring unit. The crane is capable of automatically using the gripping assembly to transport a load from an initial point to and end point where the load should be deposited while avoiding one or more obstacles in the path of travel of the gripping assembly and the load.

A crane, in particular a loading crane, includes an arm system that has a plurality of arms. The crane also has a crane controller that is configured, in a coordinate control operating mode, to control the coordinates of the arm system. The crane controller has a user interface, and the user interface has at least one function which can be selected by a user and by way of which at least one of the degrees of freedom of the arm system can be restricted or is restricted in the coordinate control operating mode.

Techniques facilitating increased operational reliability for jib cranes are provided. In one example, a jib crane can comprise a mast, a shaft mechanism, and a rod. The mast can extend vertically from a base structure. The shaft mechanism can be disposed within the mast. The rod can be coupled to a boom arm and can be disposed within the shaft mechanism. Rotation of the rod can facilitate continuous rotation of the boom arm about a longitudinal axis of the rod with respect to the base structure.

A work machine includes a lower traveling body, an upper swing body swingably mounted on the lower traveling body, a work device attached to the upper swing body, a hook attached to the distal end of the work device, an acquisition device configured to acquire information on the conveying destination of a suspended load to be suspended from the hook, and an imaging device attached to the upper swing body and configured to acquire image information related to a situation in an area in front of, behind, and beside the upper swing body. The situation includes the state of the suspended load. The work machine is configured to automatically convey the suspended load to the conveying destination by causing at least one of the lower traveling body, the upper swing body, and the work device to operate.

A crane controller for a crane, in particular a cargo crane, has a first operating mode, in which the crane can be user-operated by control commands from an operator, and a second operating mode that can be activated by the operator. In the second operating mode, the crane geometry can be changed by the crane controller in a pre-defined sequence of movements. The crane controller has a menu-drive user interface, and the interface has a function which can be selected by the operator and by which the crane controller switches from the first to the second operating mode.
