1. Introduction
Equipped with Cummins engine, strong power, high efficiency, energy saving, reliable and durable; advanced negative flow hydraulic system, comfortable operation, high operating efficiency, excellent cost performance; full power control, four power modes to adapt to different working conditions; stepper motor accurately controls the throttle , Significantly reduce fuel consumption; full 3D modeling and finite element analysis technology to ensure the reliability and stability of structural parts.
2. Characteristics
Equipped with Cummins engine, high load resistance, high horsepower output, high reliability, low fuel consumption, significantly reduce the use and maintenance costs
. Advanced negative flow hydraulic system is adopted, which has better system stability and reliability, faster compound action speed and higher operating efficiency.
High-strength reinforced box-type side beams and X-shaped middle frames, high-reliability towline wheels and track rollers, can withstand the impact caused by excessive loads.
Intelligent electronic monitoring system, real-time monitoring, self-diagnosing fault alarm, maintenance information prompt.The LC-type reinforced track has high strength and abrasion resistance, making the whole machine safer and more stable.
