The lift arm using a new type of high-quality steel(Weldox700 and Strenx700El), high strength, light weight, direct access to AC power to start, it can quickly set up safe and simple operation. The working table has large working radius and it can be 360 degrees rotated. We have advanced processing technology ,design concept, thickness optimization, technological innovation, mold optimization, equipment matching, etc., adopt reasonable boom section design , which greatly improves the strength and anti-extrusion stability of the boom barrel while the dead weight is light. Strong working capacity, strong lifting capacity, wider lifting range. While ensuring the lifting capacity of the crane, it makes the weight lighter and increases the cargo capacity of customers to improve fuel economy.
