Since 2022, each main engine factory has vigorously promoted the sales of electric loaders. According to reports, Liugong, Shandong Lingong, Liteng, Shantui, yingxuan heavy industry, XCMG and other manufacturers have electric loaders, with the largest single transaction of more than 10 units.
According to the data of China Construction Machinery Industry Association, 180 electric loaders were sold from January to March 2022, all of which were 5-ton loaders, including 85 in March.
The electric loader sold on the market can be divided into two motors and three motors. What are the differences between them? What are their advantages and disadvantages?
Three motor and double motor
XCMG xc968-ev Electric Loader adopts the scheme of three motors and no gearbox. Other brands of electric loaders in the industry mostly choose the double motor scheme.
Dual motor scheme: the permanent magnet synchronous motor provides the driving force, which is distributed to the front and rear axles through the gearbox.
Its advantages are low overall cost and relatively mature and stable technology.
Its disadvantage is that it is still difficult to get rid of the problems of gearbox prone to failure and high energy consumption.
Three motor scheme: omit the gearbox and directly drive by series double drive motor. Two motors work together or one motor works as required.
The utility model has the advantages that the gearbox is no longer needed, the maintenance cost is avoided, the walking action response of the whole machine is faster, the energy consumption loss is small, and the walking is also more energy-saving.
Its disadvantage is that it is difficult to control, the selection power of the motor is large, and the overall cost is higher. This is also the reason why its comprehensive power reaches 270kw.
The sales volume of electric loaders in 2022 is 5000 ~ 10000?
In a summit dialogue entitled "exploring the new future of electrification of construction machinery", people in an industry estimated that the capacity of electric loaders should reach 10% in 2022, that is, if the total sales volume of loaders is 100000, the opportunity of electric loading accounts for 10000. Conservatively, 5000 units can certainly be achieved.
What do you think of that? If you choose an electric loader, would you choose dual motors? Or three motors?
