Although the concrete pump truck is mostly driven by the engine when it is working, the entire circuit system of the vehicle also provides a great guarantee for the normal operation of other equipment. In addition to the need for a battery to provide current when starting, the entire circuit system is actually running at full capacity after the concrete pump truck is started.

In the current market, 99% of the concrete pump trucks are modified from the truck chassis. On the other side of the chassis, there are two batteries that can provide electricity for the entire pump truck. The battery voltage of the pump truck is still similar to that of the batteries on ordinary cars. They are all 12V standard voltages. After the two are connected in series, the voltage is 24V. However, after the engine is started, the generator will charge the battery, so the voltage continues to rise. After the pump truck has been working for a long time, it is necessary to check the battery voltage of the pump truck immediately after stopping. The voltage data obtained should all be between 26-28V. If the battery voltage is still lower than 20V when the pump truck has been parked at 3H, then it should be considered to replace the battery.

Although the concrete pump truck has two batteries, the pump truck consumes a lot of power, such as the display screen, remote control signal transmitter, remote control, etc., in addition to the power used by the various lighting equipment and cooling fans on the vehicle They are all supplied from the battery. Therefore, the power distribution system installed on the concrete pump truck is also of a higher importance in the entire vehicle equipment. Now there are more and more various vehicle circuits, unlike some old-fashioned mechanical equipment long ago, only a few wires. However, after the current power distribution system becomes more complicated, there will be higher new requirements for the line quality of the entire vehicle. Especially in the quality of each line with speed and high temperature, it needs to be well resistant to torsion and high temperature.
