The world’s largest fleet of heavy-lift equipment has just become even larger, following Mammoet‘s purchase of two new crawler cranes from Liebherr.

The Dutch heavy lifting and transport specialist has added the Liebherr LR11350 and LR12500-1.0 crawler cranes to its global fleet.

High-capacity crawler cranes

Liebherr released the LR12500-1.0 to the global market in 2022. It’s one of the largest crawler cranes it manufactures; beaten only by its bigger LR13000 sibling — a 3,000t capacity crawler that Mammoet also has in its fleet.

This investment comes as Mammoet is seeing significant growth in the renewables sector, particularly in offshore wind, where turbine heights continue to grow at pace, requiring the use of ever taller and stronger crawler cranes for their integration. 

The LR11350 crawler crane has a maximum load capacity of 1,350t and a hoist height of 220 metres. It will join ten other machines that Mammoet has in its fleet with a capacity of 1,000 to 1,350t.

The biggest lifting fleet in the world 

The LR12500-1.0 crawler crane’s 2,500t lifting power comes from its uniquely wide main boom. It has a hoist height of 200 metres, and its modular design makes it easy to transport — perfect for mobilizing to projects all around the world.

Peter van Oostrom, global projects and assets director at Mammoet, said: “To ensure we continue to have a crane fleet best fitting market requirements and most modern fleet of cranes in the world, it is important that we invest in new machines from leading manufacturers. We therefore see it being in very high demand, particularly for offshore wind projects”.

Christoph Kleiner, managing director at Liebherr said: “Mammoet has been a key partner to Liebherr for many years, providing valuable input into the development of new crane hardware. Its insight into usability and future capacity requirements is invaluable. We have a strong relationship with Mammoet and are delighted it has added two more Liebherr cranes to its world-class fleet.”
