Dual power hydraulic mining excavator can be configured with both diesel engine & electric motor: when machines move between different operating sites or the power failure occurs during operating, diesel engine will work as power unit; and during operation, the electric motor works as power unit.
Dual power hydraulic mining excavator has the electric excavator’s unique advantages of zero emission, low noise, low operating & maintenance cost, good adaptability to a wide range of ambient temperatures, etc., and also has the mobile convenience of diesel excavator.
It is configured with the world famous brand hydraulic components. The main hydraulic components, such as pumps and valves, adopt international famous brands to ensure the high quality and high reliability of the machine. The hydraulic hose adopts the international famous brand, and its excellent performance guarantees the high reliability of machine.
H-type undercarriage with disassembled featured as simple structure and high torsion-resistance, more stable and reliable.H-type undercarriage with disassembled is accordance with all standards for road, railway and sea transportation.
