The static pressure transmission technology has good automatic adaptability and maneuverability; the hydraulic pump, main valve, swing motor, central rotary joint, hydraulic cylinder and pilot operated valve are all domestic famous brands.

Introduction of application scenarios

Shihushan Wharf is the main bulk cargo distribution and stacking wharf in Xiamen Island. The bulk cargoes currently in operation are mineral powder slag (including coal mines and iron ore powder, iron ore nuggets).

Working condition: The existing loader at the wharf mainly carries out the loading of mineral powder slag, the cleaning in the field, and the short-distance transportation.

Unloading height: more than 3.2 meters; the vehicles used to transport outside the site are mainly dump trucks and trains.

Model: 5 tons long wheelbase or short wheelbase high unloading; 7 tons; 10 tons;

The existing machines: a total of 40 units 5 ton loaders (Liugong, XGMA); 4 units 7 ton loaders (Volvo); 6 units 10 ton loader.

Operating time: The average operating time of vehicles in the field is currently 5-7 hours / day. The operating time of new machines is 12-13 hours / day. The operating frequency of vehicles is not fixed. When the ship is docked and unloaded, the vehicle may work continuously for more than 10 hours, loading work evaluation rate is relatively low.

Fuel consumption (take 5 ton wheel loader as an example): 12 liters (Liugong model); 15 liters (XGMA model);

1.Adopt grid and lithium battery composite power supply technology. It can be powered directly by cables or lithium batteries. Solve the problem that crawler excavator is not flexible in moving.

2.Independently developed special load sensing control system with variable speed, large closed-loop feedback of hydraulic parameters, torque prediction and direct control of torque, global power matching, on-demand oil supply, reducing throttling and overflow loss.

3.Multi-motor coordinated control, reasonable matching of motor load, optimized energy management, efficient operation; time-sharing, automatic idle stop, reducing energy consumption of the motor and pump at idle.

4.540V high voltage solution, reducing electric current; high efficiency permanent magnet synchronous motor, intelligent door drive variable speed control, low heat generation, 20% energy saved than asynchronous motor.

5.Compound energy storage of lithium battery and hydraulic accumulator to ensure instantaneous power and endurance requirements of the energy storage unit in the same time

Zero emission, zero pollution, low noise.

Low use cost. The electricity consumption cost of pure electric construction machinery is about 30% of the fuel cost of traditional construction machinery.

Low maintenance cost. No need for regular maintenance for the diesel engine, such as replacing the engine oil and three filters, etc.High battery safety, no risk of spontaneous combustion / deflagration.

The lifespan of the battery is more than 8-year. The recycle lifespan of lithium iron phosphate battery under 1C is more than 4000 times.

Optimized energy management, excellent energy utilization efficiency and endurance, together with high-volume lithium iron phosphate battery, 7 to 9 working hours after full-charging can be guaranteed with large capacity lithium battery.
