摘要

In a method for recognition of the position of a load on a lifting gear, an active light source and a camera are mounted to a trolley of the lifting gear. Both, the light source and the camera are directed towards the load. The load has attached thereto at least one marker used for the recognition of the load position and including an active light source. In response to incoming light from the light source on the trolley, the light source of the marker transmits a light signal to the camera.
