Going from strength to strength with an upgrade to 960 yield strength
Hansin believes that it is going from strength to strength as they upgrade from conventional steel and from Strenx® 700MC to Strenx® 960 Plus. They currently produce seven AWP models, with boom lengths of 29, 32, 35, 38, 40, 46 and 56 meters. In an effort to evolve their product line, they are aiming to produce a 63 meter model (207 ft.) in 2023 to meet customer demand for booms with longer reach and greater stability.
In 2012, Hansin replaced the conventional steel in some of their models with Strenx® 700MC. Three years ago, they upgraded their 32 and 46 meter models to Strenx® 960 Plus in the booms, outriggers, sub-frames and turrets. The result? Lower overall weight and improved resistance to loads introduced by the longer booms.
According to JungSeok Kim, senior design engineer at Hansin, “Compared with a conventional steel we used before Strenx® 960 Plus, our booms now have less deflection, no buckling and better fatigue performance, which means improved safety performance.”
