XCMG Mining Excavator XE900D carries an original engine imported from America. The engine meets TIER 3 emission standard, and is featured in strong power, low noise, low fuel consumption and low emission;
It adopts genuine hydraulic components and a technologically dependable negative flow control system; it has an independent cooling system, which can automatically control fan rotating speed according to oil temperature, reduce energy consumption and lower noises; besides, the fan can reversely rotate, convenient for the dust to be wiped off from the cooler.
The traveling mechanism adopted in chassis has reinforced the bearing capacity of not only stringer and H frame, but also caterpillar track and track roller, largely increases chassis carrying capacity. The working device has adopted a box-structured lightweight design, whose crucial positions are made of solid forging, greatly reducing welding stress concentration and defects. Stress analysis and fatigue life test help guarantee enough strength and rigidness for structural parts, making it meet heavy duty excavation and mining requirements.
The electric control system, which has a good performance and a reliable quality, realizes the perfect matching of power and hydraulic system, makes the best of engine power and guarantees quick and high efficient working operation.
Lubrication system is a progressive type electric concentration system, which has a precise lubrication interval, injecting an accurate amount of grease for all lubrication points, which not only avoids omission of lubrication points by human workers but also mitigates intensity of labor.
