device associated with a crane for motion control on a hoisting rope and its applications

摘要

device associated with a crane for movement control on a hoisting rope and applications thereof the present invention is correlated with a device associated with a crane, for the control of unwanted movements of a load that is connected to a hoisting rope (14 ), through a number of secondary lifting cables (28, 29), being characterized by the fact that the crane comprises means that are arranged to propel against the secondary cables, in order to cushion and eliminate unwanted movements. according to the invention, the device is used to control rotating movements of a container, with four lifting cables connected to a hook (36) at the end of the main lifting cable (14), where the arm (22) is not bent in an approximately vertical position, the two secondary arms (28, 29) are bent in a t-shape (figure 5), the arm is rotated later, so that the secondary arms (30, 32) push the secondary cables (28 , 29) with sufficient strength to prevent the container from moving in unwanted ways. according to an alternative, a device associated with a crane is proposed to control the lifting cable itself (13) with respect to a load. in this solution, the arm (22) comprises a ring part (131, 132) arranged to be adjusted from a passive storage position in the arm part, to an active position involving the lifting cable. an application of said device is also described here
