1. Equipped with genuine imported Cummins engine with greater reserve power to provide longer service life.
2. The signal controls the engine speed and fuel pressure to achieve the best fuel efficiency.
3. The engine has good power performance and low torque and high torque to meet the needs of various mining conditions.
1. The multi-stage fuel filtration fuel system is adopted, with a filtration efficiency of up to 99%, which can effectively filter impurities and moisture in the fuel and prolong the engine life;
2. The multi-stage fuel filters are arranged in parallel to reduce the fuel resistance and meet the engine fuel requirements;
3. Equipped with a transparent water storage cup and water level alarm, which can remind the user to perform water discharge operation regularly;
4. In addition, an optional fuel electronic heater can be used to solve the problem of difficult to start the engine in cold areas;
5. The fuel filter is arranged near the aisle, which is easy to maintain and maintain.
Air filtration system
1. The air filter is equipped with Donaldson's heavy gray filter for mining, which can effectively prevent dust from entering and adapt to the operation in dusty environments.
2. The position of the air filter is set above the machine shed, which is convenient for disassembly, cleaning and replacement.
3. The air pre-filter is an integrally-installed pre-filter, and the exhaust ejection device is equipped as standard without regular dust removal.
1. Use positive flow control system:
A) The positive flow control system enables the actions of the hydraulic pump and the main control valve to be performed synchronously, and the positive flow operation is more sensitive than the negative flow.
B) An excavator with a positive flow rate can save more fuel than an excavator with a negative flow control in the case of completing the same workload.
2. Advanced XEICS control and diagnosis system, which can monitor the comprehensive use status of equipment
3. Multi-point video surveillance to ensure the comfort and safety of the entire machine
4. New intelligent electric control system, high-efficiency energy-saving power monitoring mode, hydraulic oil cooling automatic control system, new automatic idle speed system, intelligent fault diagnosis system and comprehensively upgraded electronic monitoring system to ensure the best working status of the power system and hydraulic system.
1. The hydraulic oil cooling adopts independent hydraulic circuit control. The hydraulic oil cooling automatic control system automatically adjusts the cooling air volume of the cooling system according to the temperature change of the hydraulic system to ensure the best working condition of the system.
2.High pressure filter reduces oil pollution in the system and increases the life of system components
3.Hydraulic tensioner with pressure feedback control. The hydraulic system uses the hydraulic pressure of the walking circuit to control the tension of the tracks. The large-capacity accumulator absorbs the impact caused by the car body during walking operation.
4. Multi-pump compound control realizes the best flow distribution during compound operation, making the operation more coordinated and the operation efficiency higher.
1. Elevator is used for getting on and off, which is convenient and quick. With an external filling system, fuel, oil, coolant, hydraulic oil, and slewing gear oil are all drawn to a convenient filling position for convenient maintenance.
2. The power compartment adopts a modular design. The engine, engine radiator, transfer case, and pump unit are installed in the power compartment as a whole module, which is convenient for installation and transportation.
3. It adopts overall casting to widen the track shoes, which has high strength and low ground pressure, and can be used in various working conditions.
4. The middle platform of the upper frame adopts a heavy-duty double beam box structure, which improves the rigidity of the slewing platform. Reinforced lower frame-adopts a new structural design, which improves the structural strength of the lower frame, enhances the impact resistance under heavy load conditions, and greatly improves work reliability
5. The channels are connected. The maintenance points of various functional areas such as the hydraulic system and the electrical system are connected by channels. Each channel is equipped with lighting. The interior of the power cabin is spacious and there are maintenance channels. More convenient maintenance and inspection.
6. Equipped with a fully automatic, high-power heating and cooling air-conditioning system to provide a more comfortable operating environment for the driver.
