Note: Because the boom cylinder is extended and retracted in place before oil is discharged, only one chamber of all boom cylinders is filled with oil; the other chamber is filled with oil due to the expansion and contraction of the oil cylinder, so the volume of oil contained in the other chamber is very small and can be ignored. . For example: the boom cylinder is extended in place before oil discharge,

The 32-meter pump truck boom, especially the plates of the first few arms connected to the turntable, generally use high-strength steel plates. When high-strength steel plates ensure yield strength, some indicators such as plasticity, ductility, and weldability are reduced, especially during welding. The thermal stress affected zone formed during the welding process causes the strength of the weld and surrounding areas to decrease.

In the hydraulic system of a concrete pump truck, the outrigger and arm system have certain particularities. For safety reasons, each vertical outrigger cylinder and each boom cylinder are equipped with a balance valve (commonly known as "hydraulic lock"). Only when the reversing valve is opened will the balance valve connect to the oil circuit. Otherwise, the balance valve remains closed, isolating the hydraulic oil inside and outside the cylinder.
