Features
Durable, safe and low-maintenance cranes live up to the highest
manufacturing standards. They are durable, operator-friendly, safe
and have low maintenance requirements.
Quality materials for durability
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.
Quality steel mill-certified to European EN standards.
High-quality components from suppliers represented worldwide.
Protected: For safeguarding, all components are fitted into housing
of the highest quality. Fully enclosed motors - IP55 - ensure long
lasting motor insulation.
Easily identifiable: Cables and components are numbered or marked
for easy identification, reducing maintenance time and costs.
Efficient: Virtually all internal electrical installation is done
using multi-plug connections which reduces erection time.
Safety devices:
1): Hoist height limit
2): Over speed limit
3): Over load limit
4): Lifting moment limit
5): Slewing angle limit
7): Obstruction light (tip of jib, tower head)
8): Wind lock device.
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
