The core working principle of the concrete pump truck is to drive the hydraulic pump through the chassis engine, convert hydraulic energy into mechanical energy, push the piston in the pumping system to do reciprocating motion, use the thrust of the piston to suck the concrete in the hopper into the delivery cylinder, and then push it to the delivery pipeline through high pressure, and accurately deliver it to the construction work surface through the boom placing port.

The boom can be telescoped, folded and rotated through the hydraulic system to flexibly adjust the placing angle and height; the control system can realize manual and remote dual operation, real-time adjust the pumping speed and placing position, the whole process is continuous and efficient, which can effectively avoid concrete segregation, ensure the pouring quality, and realize integrated "pumping-placing" operation.
