Strenx performance steel from SSAB has helped the Italian crane manufacturer Fassi develop a new knuckle-boom crane that is significantly lighter, while obtaining new levels of performance.
For its new F2150RAL crane, Fassi chose to use the high-strength and ultra-high-strength steels Strenx 1100 and Strenx 900 from SSAB in the lifting arms and crane booms. The result was a revolution in heavy-weight knuckle-boom cranes, which can now be installed on four-axle trucks.
The F2150RAL crane stands out for its ability to combine exceptional lifting performance with a machine body that keeps structural dimensions to a minimum and limits tare weight. It has a lifting class of 160 metric tons/1570kNm and a maximum reach of 41.30m with jib that was made possible thanks to Strenx.
Strenx is designed for areas where structural strength and weight reduction are important competitive factors. The research and development department of Fassi in partnership with SSAB worked to co-engineer new applications with extremely advanced mechanical solutions.
The development of the new Fassi crane was focused on improving the power-to-weight ratio, without sacrificing reliability or safe operation limits.
“The combination of Strenx and the expertise of Fassi has allowed for new levels of performance and reduced operating costs for the F2150RAL crane,” explained Magnus Carlsson, product manager Strenx, SSAB Special Steels.
Strenx provides high toughness, good welding and bending properties as well as good consistency in terms of physical, chemical and mechanical properties.
