MacGREGOR Cranes have introduced a new generation of cranes purpose-designed for bulk carriers of up to 60,000 dwt. The MacGREGOR-Hägglunds GLB-2 bulk crane is a two-wire model with a maximum hoisting capacity of 30 tonnes, and is available with a range of jib lengths from 18m to 30m. Optional equipment includes electro-hydraulic motor grabs of any type to handle all kinds of bulk cargo.The GLB-2 introduces a new standard in bulk handling cranes by offering many advantages over competing designs.
At the heart of the design are three independent closed-loop hydraulic systems for reliable and independent luffing, slewing and hoisting operations. These systems are controlled by a computer-based control system, which ensures better operational control with optimum performance, reliability and ease of maintenance. The new crane follows an established modular design philosophy, with all machinery weather protected within a spacious crane-house. This allows easy access for maintenance, survey and ease of future service. The jib is of box-girder construction manufactured from standard steel for ease of repair if damaged.
Type GL-2 crane
An innovative feature is the incorporation of the slip ring inside the crane-house. This facilitates ease of installation in the shipyard. It is no longer necessary to fit the slip ring on the pedestal and then mount the crane. The slip ring is fitted and fully tested in the crane factory, and the shipyard only has to bolt the crane to the fabricated pedestal from within the foundation – no staging is required around the pedestal. Greasing of the slewing ring is also done from inside the pedestal.
