Title: METHOD AND DEVICE FOR RECOGNITION OF A LOAD ON A LIFTING GEAR
Abstract:
The invention relates to a method for recognition of the position of a load or a load support means on a lifting gear and a corresponding device. The lifting gear comprises a trolley for moving the load, with an active light source and a camera mounted on the trolley, which may both be directed towards the load. The load or the load support means comprises at least one feature for the recognition of the position of the load or load support, whereby said feature comprises an active light source and a light signal is transmitted in the direction of the feature from the active light source on the trolley and, after recognition of the signal, a further light signal is returned from the feature to the camera. The operational security of such a positional recognition is thus increased.
