Dutch international heavy crane and transport group Mammoet has released more details of its Focus crane concept, with an animated video showing just how it is intended to work.
The company floated the idea for the new crane back in 2016, suggesting at that time that it might be scaled up to a maximum capacity of 24,000 tonnes. The idea is that the crane can almost set up within its overall footprint. Saving a huge amount of space and disruption, making it ideal for congested spaces, such as plants and inner cities.
The animation also shows how the crane’s superstructure is placed on a pedestal. That helps improve stability, while lowering ground bearing pressures to less than 10 tonnes per square metre on a surface of just 30 metres square. The variable super lift suspended counterweight has a tail radius that can be adjusted under load from 16 to 30 metres.
Jacques Stoof, director of innovation and market development said: “The animation shows how 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 sterilise larger parts of a plant area for crane assembly. Neither is there any more need to build over live pipe racks. 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.”
“The Focus will set a new standard of heavy lifting in confined spaces. The design that we demonstrate in this animation is based on numerous discussions with our customers in which we gained a good understanding of their current and future challenges. The Focus is a direct response to their need for greater lifting capacity and flexibility within limited and congested spaces. This innovation is a cost saving solution for many of our customers within the power, petrochemical and civil sectors.”
Production of the first Focus crane is now underway, with completion expected during the second quarter of next year. He is the video animation which clearly shows how the new concept works)
