The range of Liebherr BOS cranes includes rope luffing 
offshore pedestal cranes with an open A-frame design and 
either electro-hydraulic or diesel-hydraulic drive. Being an 
offshore crane of the 3rd generation, the Liebherr BOS crane 
stands for the highest manufacturing standards and for 
modern, innovative offshore crane technology.
Instead of a slewing bearing the Liebherr MTC cranes are fitted 
with a patented slewing mechanism, which supports precise 
handling and trouble-free operation. The MTC range includes 
modern, highly developed mast type cranes for all customers 
with a preference for non-metallic slewing systems.
With the recently introduced heavy lift concept, Liebherr is 
breaking the rules of traditional design solutions and crane 
concepts. What was expected to be tomorrow’s technology 
was implemented into these special machines. The current 
range of cranes offers fully revolving heavy lift solutions with 
lifting capacities of up to 3,000 metric tonnes and also includes 
"Around-The-Leg" designs.
Benefit through partnership – the Liebherr service philosophy 
is based on long-term partnerships and traditional values. 
Guaranteed spare parts availability for the lifetime of a crane 
and high level logistical service are only two examples of 
the unique service support Liebherr offers its customers. A 
worldwide network of service centres with 24/7 services is 
another highlight which underlines Liebherr’s commitment to 
first class customer support.
The Liebherr ram luffing offshore crane (RL) is the result of 
more than 25 years experience in the offshore industry. The 
product development is a continuous process and is based on 
the actual feedback from users all over the world. The compact 
RL offshore cranes offer medium lifting capacities and working 
outreaches as well as exemplary reliability and availability.
