The process features
1): automatic submerged arcwelding is adopted in the main section limbs and chord boom. It has highthermal efficiency, high penetration, high production efficiency, whilereducing the pores and crack defects, increases the weld strength and thebeautiful appearance.
2): we adopt carbon dioxide gaswelding; it has heat concentrated, a small welding line, high strength andresistance to rust and crack. it can reduce tress and deformation, it has highstrength and resistance to rust and crack.
3): shot blasting is used formasts to strength the hardness of steel surface; enhance the paint adhesion andprolonging its life
4): we have robot-weldingproduction lines, so the welding quality has reached international advancedlevel.
The advantages of the tower crane
1): high quality, highefficiency and high safety
2): high rigidness, resistantto corrosion and rust.
3): 20 years manufacturing andexporting experience
4): exports to 30 countries andregions
5): large lifting moment, largeloading capacity, long jib length
6): small energy consumption
Service (optional)
the seller send 2 technicians (one electrician and one mechanic) to the buyer for technical assistanceincluding supervising installation, commissioning, testing and training workersof the buyer, maintenance and dismantlement of seller’s products.
