Sheltered waters
The CBB wire luffi ng crane is suitable for multi-purpose and bulk handling on vessels up
to Panamax size. Equipped with either a single rope or motor grab these cranes are an
economical solution nevertheless providing effi cient performance.
Bulk handling and transshipment in sheltered waters can be performed by
a wide range of Liebherr cranes starting with slewing cranes with single
rope or motor grabs through to heavy duty high performance slewing
or double girder four-rope grab cranes, depending on the individual
requirements of the customer. As for cranes performing in open sea, safe
and precise crane operation is ensured with Liebherr’s own Litronic
® crane
control and management system.

– CBB 30, 32 tonnes at 32 metres in grab operation
0 tonnes at 32 metres in hook operation
• unobstructed view due to improved position of fi rst jib bracket
• double beam boom for high rigidity, less corrosion and easy repair
• luffi ng through jib bracket instead of jib head, therefore less maintenance costs,
less power consumption and higher luffi ng speed
• very reliable and easily maintained fully hydraulic control system
• hoisting and luffi ng gear of easy to maintain open loop type
• slewing gear of closed loop type for independent speed control
The CBG and MPG type cranes can also be applied in sheltered waters for loading/
unloading vessels up to Capesize. The features of these cranes as detailed in the section
