Electric hydraulic excavator for coal mine, the power unit adopts 45KW or 55KW explosion-proof electric motor, absorbs domestic and foreign
On the basis of the advantages of similar products, the self-researched, developed and manufactured underground rock loading and clearing machine is compact and flexible.
.The upper frame can be rotated 360°, which can easily realize small-section rotation, which is suitable for excavation, undercover, rock breaking, loading, etc.
According to various requirements, it can complete many tasks such as digging ditches, cleaning floating coal, cleaning slag, and leveling roadways. The working devices are three
The boom structure can adapt to the requirements of roadway operations of different heights. It is equipped with a front bulldozer, which can level the roadway.
Surface and stable fuselage, climbing ability +30°. Equipped with a quick-change high-power breaker, which is convenient for quick replacement and crushing in the well.
The hammer impact energy is 1100J.
The working device can be equipped with an optional manipulator that can rotate 360°, which can grab pipelines and U-shaped sheds, walk and transport them to the construction site
It can be installed and supported; it can also be equipped with a milling machine, which has strong power and can meet all-round milling and mining of coal and rock.
The effect of brushing and repairing is remarkable.
