Ship cranes are used in many ways. Barges with a single deck crane or large bulk carriers with four or five deck cranes. The range of crane capacities is normally between 25 and 50 ton with a working radius from 20 to 38 meters. To improve the outreach and positioning performance, the cranes can be installed on eccentric platforms. Besides the single boom cranes there are special double girder deck cranes especially designed for use on board transshippers where high turnover rates and continuous operation are required.
Self unloading stations
Some vessels are complete self-unloading stations with deck cranes, hoppers and conveyors. These self-unloaders can be used for transshipment or unloading without the need for shore-based unloading systems.
Grabs with high capacities
Verstegen is specialised in mechanical rope operated grabs for 4-rope deck cranes with large capacities for high unloading rates.
