Ram luffing cranes

The new RL crane series

Ram luffing cranes

Experience with more than 1,000 offshore cranes

The RL series - compact and versatile

The particularly weight-optimized 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.
