| Energy-saving and efficiency: |
| 1.with 13L electronic fuel injection engine of large discharge capacity produced by Volvo for Lingong, which has great power, low speed of revolution, better dynamic property and low fuel consumption; |
| 2.Automatically back to idle speed: 5s (default) after inaction of guide handle, the engine will automatically reduce to idle speed. The service lifetime of the engine is prolonged thanks to energy conservation and noise reduction. |
| 3.The hydraulic system adopts independent motor-driven fan for heat dissipation. The revolving speed of the fan could be automatically adjusted, with better dissipation effect and longer duration; |
| Reliability and durability: |
| Oil-bath air filter could make the filtering more complete and air supply safer. Under the bad condition in mine, the early-wear failure rate of engine is the lowest;Three-level oil filter, with large area and higher accuracy of filtering, makes the engine safer and more reliable during operation; |
| Comfort and environmental protection: |
| 1.With standard skylight, optional rear camera, and color LED monitor, without dead corner of view and with controllable operation status of machine.Negative flow hydraulic system commissioned elaborately by VOLVO is matched perfectly with engine, which ensures that the harmony of compound control action is better and the handfeel is facile; |
| Convenient maintenance: |
| With computer remote diagnose interface and external power source interface. After the computer is provided with diagnose program (TECHTOOL), the fault could be inspected by itself and maintenance is convenient and efficient. |
| The fan pulley could be expanded and tightened automatically, decreasing the time of shutdown and making the maintenance simpler; |
