Floating cargo cranes Open sea and sheltered water

CBG 350 The Liebherr CBG 350 is a dedicated heavy duty high performance four-rope crane with maximum lifting capacity of 35 tonnes in grab operation at an outreach of 36 metres. With a larger winch lifting capacity can be increased to 45 t at an outreach of 32 m in grab operation. Designed for high speed continuous operation, these CBG cranes incorporate specific features for heavy duty conditions and operation in open seas. A counterweight reduces the overturning moment meaning higher stability leading to increased turnover of up to 30,000 tonnes per day.

CBG 300 The Liebherr CBG 300 four-rope grab crane is designed for high speed and continuous performance. A wide rope field for stabilising the grab ensures safe operation and cargo handling without the need of an additional stabilizing winch. Specially designed heavy duty hoisting winches, heel trim alarm systems and emergency operation functions make these cranes suitable for operation in open seas. These unique features backed by Liebherr’s long and vast experience in the design, development and manufacturing of ship cranes provide high quality products for safe working conditions, high reliability...

CBG 300 with ex-centre arm The Liebherr CBG 300 cranes have a maximum lifting capacity of 25 tonnes with an outreach of 30 metres in grab operation. This outreach can be extended through an ex-centre arm of 6 or 10 metres making total outreaches of 36 or 40 metres respectively. This means that it is not necessary to reposition the barge to reach all holds during unloading, and the turnover can be increased by approx. 20% in comparison to conventional cranes.
