4、5T electric loader electrification electric conversion process and test data
The electric loader project has completed the trial production of a three-wheeled prototype. The functions meet the design requirements, and in the performance comparison experiment with the fuel loader, the traction force, the rising force, the three items and the time are significantly better than the fuel loader. Operating costs will be significantly reduced.
The first round of trial production : functional prototype
The second round of trial production: Engineering prototypes

The modified electric loader has completed multiple rounds of multi-condition performance experiments, and the operation data of the electric loader has been calculated and analyzed by CANape data acquisition and typical working conditions, and the test data are as follows:
Typical duty cycles were selected for the performance test：
They are shaded by color in the image on the left.
The duty cycle vehicle peak power: 172kW;
Average power: 39.75kW;
According to the calculation of the vehicle with a charge of 163kWh and a discharge depth of 90%, the vehicle can run for 4.1 hours when fully charged.
This electric loader can also be widely used in mining areas, open-pit coal mines, ports and other working conditions. It can realize energy saving and emission reduction in the whole process of pure electric and zero-emission operation in multiple fields, reduce costs and increase efficiency, and bring users the "double superposition" of environmental protection and economic benefits, creating new momentum for business development! PUMBAA works with you to promote the green and intelligent transformation of industrial scenarios and build a sustainable future together.
