Dutch heavy lifting and transport specialist Mammoet has announced the purchase of two new crawler cranes from Liebherr, making what is already the world’s largest fleet of heavy-lift equipment even larger.
Mammoet said in a statement that the latest acquisitions in its global fleet are a Liebherr LR11350 and a Liebherr LR12500-1.0. This is the second LR12500-1.0 purchased by Mammoet.
The LR12500-1.0 is one of the largest largest crawler cranes that Leibherr manufactures, and it was released to the global market in 2022. The model is beaten only by its bigger sibling – the LR13000, a 3,000t capacity crawler that Mammoet also has in its fleet.

Mammoet said this investment in the new cranes comes as it 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 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 LR12500-1.0’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 mobilising to projects all around the world.

Mammoet fleet responds to market requirements
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 the most modern fleet of cranes in the world, it is important that we invest in new machines from leading manufacturers. Liebherr is a worldwide supplier and the logical choice for cranes of this capacity. We therefore see it being in very high demand, particularly for offshore wind projects.”
Christoph Kleiner, Managing Director, Liebherr, added: “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.”
Mammoet revealed that the two cranes are scheduled to start work on key upcoming projects in the UK (LR12500-1.0) and the Netherlands (LR11350).
