LOOP SYSTEM EXPANSION DEVICE THAT CAN BE MOVED BY MEANS OF THREE CATERPILLAR

摘要

The invention relates to a movable conveyor belt carrier which might be used in rock-crushing or other installations where the bulk material being conveyed may be deposited at different locations along a line of travel, as defined by the belt itself. The carrier is mounted so that it has a pair of caterpillar tracks on one side of the supporting framework and a single track on the opposite side, in line with the front track on the one side. The main supporting structure is carried by the pair of tracks and the torques acting on this structure are absorbed by a transverse structure which rests on the third track. The resulting unit is strong, stable and is easily steered.
