1,Heavy-load design, robot welding, thick plate, secure welding joint, high anti-torque coefficient and high overload capacity. Technology of finite element analysis is employed to decrease stress concentration and eliminate local weaknesses. Frame is resistant to impact and overload and capable in various overload working conditions.

2,Alignment design of main hinge joint decrease s turn radius and reduces tire wear and energy loss. Large spacing between upper and lower hinged plates, high structural strength and sufficient repair space. The first manufacturer to apply double-row tapered roller bearing to main hinge joint, featuring strong bearing capacity and long service life.

3,Implementation of"service throughout full life cycle" brings about trouble-free lifetime experience! Marketing service network spread around the world covers extensive areas.

4,First-rate hydraulic element, featuring low pressure loss, little system radiation and high part reliability. Hydraulic pump of international brand provides stronger hydraulic power. Italian α hydraulic hose featuring resistance to heat and pressure, and long service life. Two layers of sealing, i.e. 24° cone plus O-ring up to DIN international standard are employed for hydraulic pipeline, which features better tightness and effectively resolves the issue of leakage. Imported materials are used for harness with optimized process layout for guaranteeing circuit system reliability.
