Engine
(1) C ummins engine, rated output power of 563Kw/2000rpm, 100-ton power, strong outburst, far more than the industry models of the same tonnage, higher operating efficiency;
(2) Smooth power output, smooth switching between light load and heavy load;
(3) Large torque output, fast response speed and good starting ability.
(4) The lowest fuel consumption rate is lower than 190g/kwh, and the fuel consumption is 10% better than that of I suzu 6WG at common speed;
(5) Sufficient power reserve, wide range of adjustment, and strong adaptability to high-altitude operation.
Hydraulic system
(1) K awasaki 280 large-displacement main pump, single pump flow rate up to 462L/min, sufficient flow, fast speed, large striking force;
(2) Low rotational speed, long life, low noise, good fuel saving effect;
(3) Kawasaki high torque double rotary motor, high torque, good starting ability;
(4) High gear meshing, small slewing drift, smoother parking.
Chain wheel structure
(1) The supporting wheel replaces the drag chain wheel, with larger wheel diameter and axle, thicker and more wear-resistant, and better supporting ability;
(2) Double symmetrical sprocket support, uniform force, good deformation resistance and high reliability;
(3) Integral chain rail clamp for mining, full-size clamping protection, reducing chain rail wear and damage, preventing chain rail wear caused by traveling deviation.
Heat dissipation system
(1) oversized fully parallel radiator, small system heat generation, hydraulic oil temperature is reduced by 10 ºC compared with similar models, long-lasting and durable.
(2) Built-in shock absorber, better anti-vibration ability for mine alternating load;
(3) Dual independent drive cooling motors, water cooling and oil cooling are independently controlled and do not interfere with each other.
Touch screen meter
(1) 8-inch touch screen instrument, integrated menu display, delicate picture, more friendly interface;
(2) One key start; convenient, fast, efficient, and more comfortable driving experience.
