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.
A Family Business with Longstanding Experience
Sommer Kranverleih GmbH is a family-run business founded in 1959, now managed by the third generation, Hagen and Björn Sommer. The company operates around 30 mobile cranes, with capacities ranging from 40 to 800 tonnes, serving Bremen and surrounding regions, while heavy-duty cranes are deployed nationwide.
Hagen Sommer said:
“It was a bold move at the time, but our success proved us right. We now operate five LTM 1750-9.1s and one LTM 1650-8.1, placing a particular focus on the heavy-duty crane class.”
Strong Partnership with Liebherr
Sommer highlighted its longstanding relationship with Liebherr as a key factor in its fleet strategy.
Björn Sommer said:
“Liebherr is a strong partner for us. The cranes retain their value well, and Liebherr also offers us special-purpose cranes that are optimally designed for specific applications.”
In addition to its heavy-duty cranes, the company also operates:
LTC 1050-3.1 compact crane
LTR 1100 telescopic crawler crane
MK 88 Plus and MK 120-5.1 mobile construction cranes
This diversified fleet enables Sommer to support a wide range of lifting requirements across multiple sectors.
