1. Use the original imported high -horsepower engine. Meet the Tier 3 emission standard, has the characteristics of powerful, low noise, low fuel consumption, and low emissions, which can meet the needs of various construction conditions. The high -pressure fuel injection system is adopted, and the fuel injection process is fully electronically controlled through the control of the ECM oil supply actuator and the timing actuator,
precisely control injection amount and time of injection, reduce fuel consumption and increase engine efficiency;
2. Optimize configuration of key hydraulic components, use larger diameter and higher pressure main valve, integrated output agency's rotation reducer and larger walking reducer, so that the XE950D can obtain larger hydraulic energy, larger capacity, larger ones Rotating and walking driving power is more suitable for bad mines.
3.The traveling mechanism adopted in chassis, strengthen the loading capacity of the longitudinal beams and H, strengthen the chain rail, branches, etc., and greatly improve the carrying capacity. The working device adopts the lightweight design of the box structure. The key parts adopt the overall forging structure, which greatly reduces the welding stress concentration and defects. Through stress analysis and fatigue life test, the strength and stiffness of the structural parts can be ensured, making it satisfy heavy duty excavation and mining requirements.
4.
The engine air intake system adopts cyclone tube type pre-filter, and at the same time adopts the engine exhaust gas dust discharge pilot technology, which can automatically discharge the dust in the pre-filter, and the separation effect of the pre-filter reaches more than 90%, which greatly extends the use cycle of the air filter and reduces the replacement cost of the filter element. The air intake system adds exhaust gas dust emission device to achieve automatic dust removal from the air filter, reducing dust accumulation, improving the service life of the filter element and reducing the user's cost of use.
5. Using a single -line electric centralized lubrication system, the lubrication cycle is accurate, the quantitative fat gives accuracy, avoid artificial fat omissions and lubrication points, and saves human labor intensity.
