- How to maintain the 32-meter pump truck to prevent the boom from breaking?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.Sep 4,2023
