Each elevator link of one pair is forged from one single billet of high strength alloy steel, heat treated, surface-strengthen treated and NDT for super performance
and long service.
The rating loads of elevator links series are
150t(1350kN),200t (1800kN),250t (2250kN),350t (3150kN),500t (4500kN).
All the technical data and properties of elevator links completely conform to the requirements of SY/T 5035 and API Spec 8C.
