摘要： In a method for preventing a collision of a load of a crane with an obstacle, a height profile of the obstacle is captured along a trajectory of movement of the load by at least two sensors for distance measurement. Signals of the sensors are transmitted via at least two communication channels to a controller having at least two operating systems. At least one of the operating systems has a safety program in a secure area. The obstacle is identified along the trajectory via the height profile. The controller includes a secure communications interface for transmitting signals from the controller to a crane control.
