Concrete mixing tube axis vertical plane

National truck driving the direction of rotation of the mixing tube is usually their eyes on a side road vehicles driving regulations to determine. According to China's traveling road vehicles driving on the right provisions, most domestic truck driving jobs in agitation, mixing tube rotation direction is clockwise (facing the rear look ahead, clockwise rotation), corresponding to the mixing tube spiral blade rotation is L. This arrangement is adapted to the right lane highway right low left high section of the actual situation. Concrete batching plant designed truck in the vehicle's center of gravity conditions agitation mixing tube axis vertical plane, right off the vehicle centerline 50 ~ 100mm, makes the truck a few slightly better lateral stability. Due to historical reasons, China stir some truck driving job, the direction of rotation of the mixing tube is left (facing the rear look ahead, counterclockwise rotation), corresponding to the mixing tube spiral blade rotation is right-handed. This arrangement makes precast concrete plant sinistral truck agitation conditions in the vehicle's center of gravity leftward, not suited to driving on the right road when the right low left high section of the actual situation, with increasing lateral inertial force generated by the roll negative torque, resulting in relatively poor lateral stability of the vehicle. However, the design of the mixing tube alone does not eliminate bias truck rollover.
