Actuator for the correction of transverse movement of the conveyor belts is used for automatic correction of transverse turning conveyors and keeping grip tape within a given range of movement corresponding to the set end-strip detectors. The actuator works synchronously with the starting of the conveyor belt and is mounted on the drum inflection. The pump flow rate can be changed, which directly affects the sensitivity, speed, responsiveness of turning cylinder. On the cylinders are mounted control check valves that do not allow loosening and control the speed. By customer request the actuator can have other technical characteristics. In the same way it is possible to simultaneously do the correcting of movement and automatic tensioning without additional weights.
