The RL series - compact and versatile
The particularly weight-optimised and compact design is the characteristic feature of the RL series.
On both fixed and floating offshore installations, especially in the wind power industry and in the oil and gas sector, RL cranes are mainly used for maintenance and supply work.
Equipped with Liebherr Intelligent Maintenance (LiMain), the cranes have reduced maintenance efforts and thus increased crane availability at lower costs.

Highlights of the RL series
Customers voice
"For platform operators, weight and space requirements for equipment are key cost elements. Any reduction ensures savings, which is why Liebherr's RL crane is the number one choice. It is lightweight, reliable and flexible in terms of positioning. In addition, our crane operators are delighted with the ease of maintenance and sensitive crane control."

The RL series in a nutshell
- Design
- Cabin
- Maintenance
- Service
Design
Based on our customers feedback, we optimized the RL to become the most compact maintenance crane. This results in a reduced construction height and a small tail radius. The elimination of a machinery house allows the crane to operate in confined space conditions and environments. Additionally, the crane can be ex-certified (ATEX and IECEx).
Cabin
The 7m³, highly ergonomic cabin with its modern equipment ensures low-fatigue working. It offers large front, side and roof windows with windscreen wipers and integrated sun blinds for optimal all-round visibility, a new driver's seat with wide, adjustable armrests and attached master switches as well as a new climate control concept with integrated air conditioning and heating as well as air outlets at top and bottom.
Maintenance
Despite compactness, the new design offers plenty of space for maintenance with additional service platforms and lots of room inside the slewing column. The main components of the crane are part of a major modular construction concept for several offshore cranes. This approach enables an even more improved spare parts supply due to the significantly increased interchangeability of these components. Liebherr Intelligent Maintenance (LiMain) is also available for this crane series.
Service
Wherever you are - we are there, too. Our well-organized worldwide network of highly qualified, experienced engineers and technical advisors, is available for our customers in order to ensure shortest response times and highest productivity.
Available for the RL series: LiMain
LiMain is a fully digital, remote and semi-automatic maintenance system, which saves investments and resources for the platform operator.
Ram luffing crane: special features in detail
Depending on the model, lifting capacities of up to 100 tonnes are possible. The RL crane can be electrically or diesel-hydraulically powered and is available according to the required classification for maximum safety in hazardous areas.
The small tail radius as well as the low construction height make the ram luffing crane an ideal application for small and unmanned platforms or vessels.
-
Winches relocated to the boom
Easier and safer handling of the crane due to no adjusting of rope lengths during luffing needed
-
High comfort cabin
Improved ergonomics and new air conditioning ensures low-fatigue work even in difficult offshore conditions
-
A new age of maintenance
LiMain, modularity of main components and additional platforms ease all maintenance processes to a minimum
-
Compact design
Machine house included in slewing column resulting in a small tail radius
See the difference: New design approach based on customer feedback
The next generation of our RL series has been redesigned to meet the future demands of worldwide offshore customers and their individual specifications. A consistently expressed customer preference is to achieve the most compact design possible with a small radius and low overall height.
EXpressure
A special feature of the new RL crane series is the innovative cabinet inside the slewing column. The technology behind this innovation is called "EXpressure", the world's first explosion-proof Ex d cabinet that safely releases explosion pressure. It has been developed by our partner R. Stahl AG.
LiMain remote maintenance showcase
To avoid having to send service personnel to offshore platforms for every maintenance job, the demand for remote-controlled maintenance systems is growing rapidly. We recognised this trend early on and developed Liebherr Intelligent Maintenance (LiMain). It paves the way for an even higher crane availability at lower operational costs (OPEX) on offshore. The fully digital, semi-automatic, and remote maintenance system offers more independency of time, place and resources for platform owners, resulting in never-before-seen savings.
