Liebherr Introduces CBG 310 Four-Rope Grab Crane

The replacement of two long-serving cranes marks a targeted upgrade that preserves established vessel geometry while unlocking measurable gains in efficiency, durability and handling precision.  www.liebherr.com Liebherr Maritime Cranes has introduced the CBG 310, a four-rope grab crane developed as the direct successor to the CBG 300 for bulk handling and transshipment operations. The new model features elevated hoisting speeds, expanded lifting capacity, structural maintenance updates, and integrated digital assistance systems for floating and land-based installations. Mechanical Performance and Structural Updates The CBG 310 achieves a maximum hoisting speed of 130 meters per minute, representing a 44 percent increase compared to the CBG 300 to support faster handling cycles and reduced vessel turnaround times. The crane delivers a maximum lifting capacity of up to 45 tonnes in hook operation. The standard configuration features a 30-meter boom length for floating transshipment platforms, with an extended outreach option of up to 32 meters available for land-based installations. Operator visibility and ergonomics are updated via an enlarged cabin with an internal volume of 7 cubic meters. To lower lifecycle maintenance requirements, the slewing column transitions from flexible hydraulic hoses to integrated rigid piping, reducing maintenance exposure. Commercial Fleet Deployment on Eccentric-Arm Configurations Rocktree, a global transshipment and logistics provider for dry bulk commodities, selected two CBG 310 cranes to replace its previous CBG 300 units following eleven years of continuous operation. The deployment marks the first installation of CBG 310 cranes on vessel eccentric-arms. By retaining the vessel's established eccentric-arm geometry, the upgrade maintains operational alignment while increasing bulk material throughput and handling responsiveness. Giovanni Colotto, Managing Director & Head of Fleet at Rocktree, stated that moving to the CBG 310 allows the company to build directly on operational experience while achieving improvements in handling speed and lifting capability. Digital Control Systems and Collision Avoidance The CBG 310 integrates Liebherr’s Litronic control system to coordinate crane kinematics during transshipment cycles. The digital architecture includes SmartGrip technology, which automatically adjusts grab penetration and closing behavior in real time to optimize bucket fill rates and minimize material spillage. Safety monitoring is supported by LiCAS (Liebherr Collision Alert System), which continuously measures proximity distances between adjacent Liebherr cranes and alerts operators to potential collision risks in multi-crane or confined operational environments. Tim Ladendorf, Head of Sales Ship Cranes, Port and Transshipment Solutions at Liebherr-Rostock GmbH, noted that the CBG 310 delivers a step forward in capability while preserving the handling philosophy trusted by operating crews. Global technical support, spare parts availability, and service responsiveness are managed through Liebherr’s sales and service network.
