On September 25, 2025, a magnificent delivery celebration took place at the production base of Shanzhong Machinery LLC. The custom SZ420D long arm crawler excavator, independently designed and manufactured by the company to meet the specific needs of an important customer, has officially left for delivery. With the roar of the engine, this high-performance equipment traveled to the site of a client's major construction project, where it would soon be put into intensive operational tasks, bringing a powerful impetus to the efficient progress of the project.

The extended long arm of the SZ420D crawler excavator is undoubtedly its key feature, and every detail reflects the fine production technology of Shanzhong Machinery Co., Ltd. The manipulator has a fully reinforced box structure, is made of high-strength wear-resistant alloy steel and has passed stringent pressure and fatigue tests. This not only increases its lifting capacity by 30% compared to conventional long cranes, but also significantly extends its service life under harsh operating conditions, effectively reducing customer downstream maintenance costs.

For challenging operating conditions such as open pits and large infrastructure projects, the SZ420D's long arm and strong overall operating performance make it easy to handle tough jobs such as intensive mining, slope cutting and land leveling. The intelligent energy-saving control system installed on the equipment can automatically adjust the injection fuel quantity according to the workload, achieving a balance between high operating efficiency and low fuel consumption.

In addition, the equipment has excellent operating stability and strong environmental adaptability. Wide and thick belt with anti-slip design ensures stable performance even on muddy, rocky or steep slopes. The fully enclosed cab is equipped with a shock-absorbing seat and an intelligent operating panel, which not only improves operator comfort but also effectively isolates dust and noise. It can work normally in extreme conditions such as high temperature, low temperature and high altitude.
