 The advantage:

Automatic energy saving storage systerm

Work principle: Efficient energy saving excavator works cited Newton’s first law, namely, the enegy generated when the “Apple fell from the tree”, through automatic storage system to recover, so that when the excavator work needs to be released and applications.

Differences between the High efficient, Energy-saving and Environment friendly and the ordinary ones: ordinary hydraulic excavator need the engine power for lift, and the working device of excavator itself weights 1/4 of the total weight of excavator, every lifting movement consumes 70% of energy, and the energy is wasted in lifting the working device, a special energy storage system for the working device was invented, which enables the excavator to be more fuel-efficient, higher efficiency. The energy of lifting the working device is no more to be wasted, replaces the working device’s weight with the weight of the earth and stones.

HIGH EFFICIENT

1, Bucket of capacity of 3.2 equipped, as twice big as standard, doubles the efficiency under same power condition. Engineering science is applied in computing bucket structure. Larger capacity bucket, less weight, effortless excavation, stronger and longer life service.

2, Ultra filtration is executed for the hydraulic oil in the whole machine to clear contamination in the oil and reduce the frequency of oil replacement, which guarantees the liability of the hydraulic system.

3, shuanglai special hoses independently developed are equipped for the whole machine with longer life service and better liability. Unique accumulation system ensures lower engine power and higher efficiency, decreasing seals aging and oil consumption.

4, Equipped with genuine Cummins engine, high powered, Euro III emission standard satisfied, and fuel consumption reduced with high efficient in operation.

5, Optional with axial pison pump of large capacity developed by CCHC, with constant power, negtive flow control, short response time, wide adjusting range, and low power loss.

6, Optional with double swing motor developed by CCHC, compact structured, with large starting torque, steady rotation, and precise control, safe and reliable.

7, Stick Boom reheneration: While the swing arm going down and bucket rod moving back, the flow regeneration valve in the main control valve and the anti-suction will be engaged, make part of hydraulic oil flow back to ensure stable and fast work, realize energy saving.

8, Excavator swing arm and bucket rod control system: the holding valve of main control valve, can minimize the natural slippage of hydraulic cylinder caused by the leakage of the control valve.

9, Comfortable operating environment: the ergonomic design, comfortable and spacious cab, and Germany designed seat, all guarantee the driver convenient and comfortable operation. Safe and energy saving. Optional with grid hard for whole or lower part of the cab.

10. The control pilot for the whole machine is sensitive and flexible, efficient, energy-saving.
