70 Ton Mining Excavator XE700D China Heavy Duty Hydraulic Crawler Excavator for Coal Mine.
More energy-conservation and environmental protection
* By adopting the international famous brand engine. It meets TIER 3 emission standard, with advantages of strong power, low noise, low fuel consumption and low emission, and is able to meet demands of various construction conditions.
* It adopts high-pressure fuel injection system, and may realize electric control of the whole course of fuel injection through controlling fuel supply actuator and timing actuator with ECM, so as to exactly control fuel injection amount and fuel injection time, thus reducing fuel consumption and enhancing engine efficiency.
More reliable and durable
* XE700D adopts STG series heavy grayscale air filter imported with original packaging from the USA, with filtering efficiency reaching 99.99%,and adapts to working conditions with much dust and humidity.
* XE700D is set with three-stage fuel filtering system (one stage for coarse filtering and two stages for fine filtering) to effectively filter sundries in fuel, thus making sure the engine can run continuously and reliably with high load for a long time under severe working conditions.
It adopts the latest type visualized oil-water separator, and the replacement time of filter element can be judged according to fuel level; the oil incoming resistance will not change during the whole course of filter element using, so the filter element cost is lower, thus reducing customer's maintenance cost.
