The WJ-3 diesel scooptram is powered by a German original DEUTZ engine, which gives it the characteristics of low emissions and low pollution. The transmission system adopts our independently developed hydraulic torque converter and power shift gearbox, which is easy to operate and runs smoothly. The fully hydraulic dual pipe working brake system is equipped with multi disc wet brakes and our independently developed NO-SPIN anti slip differential, which is safe and reliable when working in harsh environments and high water content muddy tunnels. The main components of the hydraulic system come from well-known domestic and foreign manufacturers. The manual directional valve controls the steering, and the pilot valve with an ergonomic handle controls the lifting and tilting of the bucket arm.
