Equipped with Isuzu 6WG1 engine, power 382kW, to achieve surging power output low fuel consumption, large torque, high durability, fast dynamic response, higher work efficiency. Equipped with Kawasaki fully electric control main valve and main pump, double rotation to improve the rotation torque, rotation more smooth large displacement main pump, heavy duty P-O power increase control, balance fuel consumption on the basis of improving mining efficiency, mining sustained force, electromagnetic proportional valve integration, flow distribution efficiency high compound action smooth. SCR+DOC+DPF post-treatment technology has high nitrogen oxide conversion rate, optimized combustion, increased power and torque, greatly improved fuel economy, and cleaner emissions. The comprehensive application of 20,000-hour working device technology, the use of high-strength steel + high-strength forging + wear-resistant steel casting integrated connecting rod, Three-section box structure, the section of the box is widened, the bending section coefficient is increased by 20%, and the reliability is high and the life is long
