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
Description
1. The Fixed Tower crane base fixed to the ground on a concrete
foundation
2. The base is then attached to the mast sections which gives the
crane its height.
3. Further the mast is attached to the slewing unit that allows the
crane to slewing.
4. The horizontal jib (working arm) is the part of the crane that
carries the load.
5. The counter-jib carries a counterweight while the jib suspends
the load to and from the center of the crane.
6. The crane operator usually stay in the cabin at the top of the
tower.
7. The lifting hook is operated by the operator using electric
motors to manipulate wire rope cables through a system of sheaves
which lift the building materials
