September 8 - Mammoet and Stoof Engineering and Innovation (Stoof E&I) are joining forces to develop a new type of heavy lift crane.

Mammoet says that the new crane, which has been dubbed Focus, is designed to facilitate easy and fast assembly, lift ultra-heavy loads and provide excellent manoeuvrability in confined areas.

Mammoet adds that it will be possible to fully assemble Focus on site in confined areas, with the whole assembly process taking place in a vertical direction as opposed to the conventional assembly of cranes, which tends to take place on the ground.

There will be no need for auxiliary cranes since lifting capacity is integrated into the design, explained Mammoet, making the Focus and its boom sections self-erecting. It will also be possible to containerise the machine for delivery to sites.

The crane is expected to have a lift capacity of up to 24,000 tonnes, which Mammoet claims is higher than any capacity offered by cranes currently available.

It is also designed to allow for variable distances between the mast/boom foot and the counterweight with a load in the hook. This can even be done while the crane is slewing, and provides unique manoeuvrability regardless of the radius involved, said the Dutch heavy lift specialist.

Stoof E&I was founded by Piet Stoof, former technical director at Mammoet, who invented the MSG 50 (Mammoet Sliding Gantry), which had a maximum load moment of 50,000 tonne-metres and allegedly paved the way for the development of the company's ring cranes.
