Mammoet has started construction of its Focus crane – a heavy lifting solution for use in confined spaces such as plants and inner cities.
Jacques Stoof, Mammoet’s director of innovation and market development explained that the main boom is erected vertically with the help of a climbing frame. Once the main boom is in place, the back mast can be installed vertically as well.
“This eliminates the need to sterilize larger parts of a plant area for crane assembly. Neither is there any more need to build over live pipe racks in a plant. All in all, the assembly process is less complex, safer and more efficient, and significantly reduces the costly area and downtime of assembling a crane,” he said.
The Focus crane’s upper structure is placed on a pedestal, which enhances stability and lowers ground bearing pressures to less than 10 tons (9.07 tonnes) per sq m on a surface of just 30 m x 30 m.
The first Focus crane will be available in the second quarter of 2020.
