Sommer Expands Heavy-Lift Fleet with Fifth Liebherr LTM 1750-9.1

German crane rental company Sommer has taken delivery of its fifth Liebherr LTM 1750-9.1, reinforcing its focus on heavy-duty lifting and wind energy projects.

30-Second Takeaway Sommer Kranverleih GmbH has taken delivery of its fifth Liebherr LTM 1750-9.1 mobile crane, further strengthening its position in the heavy-duty crane segment. The 800-tonne cranes are primarily deployed in the wind energy sector, where their high performance and rapid set-up capabilities support installation, maintenance, and repowering projects across Germany. Fifth LTM 1750-9.1 Strengthens Heavy-Lift Strategy German crane rental company Sommer Kranverleih GmbH has expanded its fleet with another Liebherr LTM 1750-9.1 mobile crane, bringing the total number of this model in its fleet to five. The Bremen-based family business is placing a strong emphasis on the heavy-duty crane class, with the 800-tonne LTM 1750-9.1 forming a core part of its lifting capabilities. The company also operates an LTM 1650-8.1, with an additional unit of that model scheduled to join the fleet later this year. Built for Wind Energy Applications The Liebherr LTM 1750-9.1 mobile crane is widely used in the wind power sector, where Sommer deploys its fleet for both installation and maintenance work. Key applications include: Installation of lower concrete tower segments for modern wind turbines Maintenance and repair operations on existing turbines Replacement of heavy components Wind energy repowering and decommissioning projects For complete turbine assembly, the LTM 1750-9.1 typically works alongside larger lattice boom cranes, which handle the upper tower sections, nacelle, and rotor. High Performance with Fast Set-Up One of the defining features of the LTM 1750-9.1 is its ability to combine high lifting performance with short set-up times. The nine-axle mobile crane is designed so that its entire telescopic boom can be transported on public roads, reducing mobilisation complexity and improving efficiency on site. This makes it particularly well suited for projects where speed and flexibility are critical. Expanding Applications Beyond Wind While the wind energy sector remains a primary focus, Sommer also deploys its heavy-duty cranes across a range of industries, including: Industrial lifting projects Chemical sector operations Bridge construction The new crane’s first assignment will involve a tandem lift alongside another LTM 1750-9.1 from Sommer’s fleet, demonstrating its capability in complex heavy-lift operations.
