The working environment of dump trucks is generally based on the field and construction site, and most of them are non-paved roads, such as sand and gravel and dirt roads, which requires vehicles such as dump trucks to have good power performance, bearing and flexibility performance, safety and comfort performance. As an important device for the power transmission of the dump truck, Zhanhao has strengthened the material structure, steering angle, balance performance, power torque bearing, and corrosion resistance of the assembly, so as to better adapt to the actual working conditions and actual operation structure.
Assembly-related standards and data
1. The rated working torque of the transmission shaft assembly is 500N.m, and the guaranteed load > 1000N.m.
