Technical Field

[0001] The utility model relates to the technical field of vehicle connecting parts, in particular to a chassis wiring harness for a pump truck. Background Art

[0002] A pump truck is a mechanical equipment specially used for transporting and pumping concrete. It is usually composed of a vehicle chassis and a pumping device mounted on the vehicle. The wiring harness is an important component connecting the pumping device and the control system. It can transmit power signals and control signals, so that the operator can accurately control the operation of the pumping device through the control system to ensure the safe and accurate delivery of concrete.

[0003] When traditional wiring harness devices are used to bind wires, the tightly bound wires will also cause the insulation material to wear due to friction, increasing the risk of short circuits.
