1. Durable, safe and low-maintenance cranes live up to the highest manufacturing standards. They are durable, operator-friendly, safe and have low maintenance requirements.
2. Quality materials for durability
3. Our components are traceable back to original premium-quality manufacturers, ensuring that they can easily be replaced when necessary. The quality of our components assure good resistance to fractures under conditions of high loading and low temperatures.
4. Quality steel mill-certified to European EN standards.
5. High-quality components from suppliers represented worldwide.
6. Protected: For safeguarding, all components are fitted into housing of the highest quality. Fully enclosed motors - IP55 - ensure long lasting motor insulation.
7. Easily identifiable: Cables and components are numbered or marked for easy identification, reducing maintenance time and costs.
8. Efficient: Virtually all internal electrical installation is done using multi-plug connections which reduces erection time.

The process features
1) Automatic submerged arc welding is adopted in the main section limbs and chord boom. It has high thermal efficiency, high penetration, high production efficiency, while reducing the pores and crack defects, increases the weld strength and the beautiful appearance.
2) We adopt carbon dioxide gas welding; it has heat concentrated, a small welding line, high strength and resistance to rust and crack. it can reduce tress and deformation, it has high strength and resistance to rust and crack.
3) Shot blasting is used for masts to strength the hardness of steel surface; enhance the paint adhesion and prolonging its life
