Under certain special conditions, if the power supply is supplied, the machine will not move or move very little. The working conditions are simple -- pure loading, unloading, hydraulic hammers and so on.
In view of saving energy and reducing emissions and reducing noise, some users in China have used pure electric drive excavators to work. There have already been special posts in the forum. The earliest machines have been used for nearly thirty thousand hours, and the hydraulic system has been replaced.
Because the machine, in the manufacturer's small tonnage, disdains the electric drive - all the hundreds of tons of large machines have an electric drive, the domestic users can only rely on the specific work of the modified plant.
According to the customer's demand, we cooperate with the refitting factory to convert the standard CAT336D series hydraulic excavator into the electric hydraulic excavator which is driven by pure electric drive. After 8 months' trial operation, we have achieved a great success.
Unlike other brands, they are:
This modification is a high index, strict requirement, do not know to change a motor, press a knife switch, push up, can turn low end modification, but has reached:
1, the power and speed are exactly the same as those of the original machine.
2, according to the needs of the operation, the 3 stage variable speed operation can be realized.
3, the independent cold and hot air conditioning operation system, such as idle waiting, does not require the main engine to operate.
4, under the maximum load per hour, the power consumption is no more than 130 degrees. Under the same working condition, the fuel consumption needs 35-38L.
5, the noise reduction is about 8dB;
6, no longer expensive diesel injectors due to poor diesel quality.
7, do not need to overhaul the engine; suitable for power supply conditions of wharf, mine, stone yard and so on do not need frequent shift operation environment.
8, the current 5,5 yuan diesel price calculation, saving about 60 yuan per hour of energy costs;
