Strenx® performance steel has the right strength for the world’s No. 1 crawler crane, the XCMG’s 4000-ton model
Tension bars in Strenx® 1100 E a safe choice in XCMG’s record-breaking crawler cranesSUBSCRIBE TO NEWSLETTER
This lifting giant is the world’s largest crawler crane. The XGC88000 has a maximum rated lifting moment of 88,000 tf·m, which translates to a maximum lifting capacity of 4000 tons. Strenx® 1100 E has been the high-strength structural steel of choice for the Chinese company Xuzhou Construction Machinery Group Co., Ltd. (XCMG).
Tension bars are components made to withstand high tensile forces and help with the global stability in structures such as cranes, buildings, bridges and much more. In the XGC88000, tension bars are used to secure a rigid connection between the crane booms and the counterweights on the ground.
Safety is paramount in lifting equipment, and the reliable and consistent mechanical properties of Strenx® performance steel fulfil all the strict demands from the customers and the regulating bodies. Strenx® 1100 E has been used in the XGC88000 crane from the beginning and the tension bars are cut from plates at the SSAB Kunshan facility according to XCMG’s own design. Before the product was put into production, SSAB gave advice on material selection and handled all the pre-production testing.
Strenx® 1100 E has a minimum yield strength of 1100 MPa. With such a strong steel, the tension bars can be made thinner, reducing the weight for easier handling and lower transportation costs. The consistent properties, guaranteed dimensional tolerances and high surface quality of Strenx® 1100 E makes cutting and machining easier and more predictable. The stable workshop performance gives maximum yield and a cost-efficient production process. XCMG knows that all tension bars live up to the same high standards for strength and safety.
“XCMG is one of the leading companies in this industry. When we design and launch a new product such as the XGC88000 crawler crane, only the most reliable materials are used to ensure safety, stability and customer satisfaction. Strenx® performance steel is definitely the perfect choice. It has all the qualities we expect from an SSAB product, and the support we get from SSAB is very valuable.” XCMG Crawler Cranes technical department.
