Abstract
A control system is provided for a conveyor bridge with a plurality of segments and equipped with individual traveling gears for the cyclic traveling (moving) on a surface in travel straight ahead and in a curve. The control system follows a process including the steps of: detecting positions of both ends of the segments of a conveyor bridge on terrain; calculating target coordinates for the control of the conveyor bridge; simultaneous switching on of the drives of all traveling gears; synchronously controlling the drives of all traveling gears; during the travel movement, constantly measuring the distance covered by each traveling gear; constantly measuring angular deviations from the straight line between two adjacent segments during the travel movement; providing a lateral slope compensation between the traveling gear and the support frame of each segment; and providing a fine alignment of all segments after reaching the target coordinates.
