Off road dump truck BZK D20 adopts optimization design of lifting hydraulic system and lifting mechanism and is steady to lift and easy to operation. The predominant single-stage deceleration technology of rear axle makes the transmission efficiency high, which saves the oil. The advanced load sensing valve ensures that the braking of the vehicles is steady and safe in different load and deceleration conditions. So it can meet various needs of engineering construction and short-distance transportation. The maximum loading capacity of off road dump truck BZK D20 is 20000KG and it is widely used in the transport of ore, gravel and earthwork and others.
