Abstract
A device associated with a crane is described for the control of unwanted movements of a load that is connected to a hoisting line () via a number of branch hoisting wires (), and it is characterised in that the crane derrick comprises means that are arranged to push against the branch wires to dampen and eliminate the unwanted movements. According to the invention the device is used to control rotary movements of a container with four hoisting wires connected to a hook () at the end of the main hoisting wire () and the arm () is unfolded into an approximately vertical position, the two branch arms () are folded out into a T-shape (FIG.), the arm is rotated further so that the branch arms () push against the branch wires () with a power sufficient to prevent the container from moving in unwanted ways. According to one variant, a device associated with a crane is proposed for the control of the hoisting line () itself for a load. In this solution the arm () comprises a hoop part () arranged to be adjusted from a passive, storage position in the arm part to an active position encircling the hoisting line. An application of the device is also described.
