Mammoet Expands Heavy Lift Fleet with New Liebherr Crawler Cranes

30 Second Takeaway

Mammoet has further strengthened the world’s largest heavy-lift fleet with the addition of two new Liebherr crawler cranes: an LR11350 and a second LR12500-1.0. The investment reflects rising demand for large-capacity lifting solutions, particularly in the offshore wind sector, where increasing turbine sizes require higher lifting capacities and greater reach.

Continued Investment in Large-Capacity Lifting

Mammoet has expanded its global heavy-lift fleet with the purchase of two new Liebherr crawler cranes, adding an LR11350 and a second LR12500-1.0. The acquisition reinforces Mammoet’s position as the owner of the world’s largest heavy-lift equipment fleet and reflects ongoing investment in modern, high-capacity lifting solutions.

The addition of the second LR12500-1.0 further strengthens Mammoet’s capability at the very top end of the crawler crane market.

Supporting Growth in Renewables and Offshore Wind

Responding to Increasing Turbine Sizes

Liebherr introduced the LR12500-1.0 to the global market in 2022. It is one of the manufacturer’s largest crawler cranes, surpassed only by the 3,000-tonne LR13000, which is also part of Mammoet’s fleet.

The latest investment aligns with growing demand from the renewables sector, particularly offshore wind. As turbine heights and component weights continue to increase, larger and more powerful cranes are required to support installation, erection, and integration activities.

Crane Capabilities and Specifications

LR11350: High Capacity and Reach

The LR11350 offers a maximum load capacity of 1,350 tonnes and a hoist height of up to 220 metres. It will join ten other cranes within Mammoet’s fleet in the 1,000–1,350 tonne capacity class, strengthening the company’s ability to support large-scale infrastructure and energy projects.

LR12500-1.0: Ultra-Heavy Lift Performance

The LR12500-1.0 delivers a lifting capacity of 2,500 tonnes, achieved through its uniquely wide main boom design. It features a hoist height of 200 metres and a modular configuration that simplifies transport and enables rapid mobilisation to projects worldwide.

Industry Perspectives

Long-Term Fleet Strategy

Peter van Oostrom, Global Projects and Assets Director at Mammoet, said

"The company continues to invest in new equipment from leading manufacturers to ensure its fleet remains modern and aligned with evolving market requirements."

He added that

"Liebherr is a logical supplier for cranes of this capacity and noted strong expected demand for the new machines, particularly within offshore wind projects."

Christoph Kleiner, Managing Director at Liebherr, highlighted Mammoet as a long-standing partner, noting that operational feedback from Mammoet plays a key role in supporting the future development of Liebherr crawler cranes.

Upcoming Deployments
