The process features:
1): automatic submerged arc welding is adopted in the main sectionlimbs and chord boom. It has high thermal efficiency, high penetration, highproduction efficiency, while reducing the pores and crack defects, increasesthe 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 canreduce tress and deformation, it has high strength and resistance to rust andcrack.
3): shot blasting is used for masts to strength the hardness ofsteel surface; enhance the paint adhesion and prolonging its life
4): we have robot-welding production lines, so the welding qualityhas reached international advanced level.
Safety devices: 1): hoist height limit 2): over speed limit 3) over load limit 4):lifting moment limit 5): slewing angle limit 6): emergency stop button 7):obstruction light (tip of jib, tower head) 8): wind lock device.
