METHOD AND/OR DEVICE FOR DETERMINING THE OSCILLATION OF A LOAD SUSPENDED BY LIFTING EQUIPMENT, THE AXIS OF SAID OSCILLATION RUNNING IN THE LIFTING DIRECTION

摘要

The invention relates to a method and a device for determining the oscillation of a load (23, 24) suspended by lifting equipment (1, 36), the latter comprising a crab (3), which is equipped with a camera (8). The camera (8) can be oriented towards the load (23, 24). The load (23, 24) has at least two marks (29, 30) located at a distance from one another, one mark (30) lying on the axis of an oscillation, said axis running in the lifting direction. An oscillation of the load (23, 24) can be determined from the position of two marks (29, 30), whereby at least one mark is recorded by the camera (8) and the position of said mark is determined. The oscillation is at least partly determined by the inclusion of a virtual position of a mark.
