Florida-based All Crane Rental has used its 660 tonne capacity Manitowoc 18000 crawler crane to help repair a ship at the Grand Bahama Shipyard, off the East Coast USA.

The repair was expected to take around 45 days and included the replacement of eight drill heads. To get to site, the 18000 was transported from ALL’s Atlanta branch by trucks, before being shipped via ferry to the dock in Freeport, Bahamas.

To remove the old drill heads and install the news ones, the 18000 was configured with a wheeled Max-Er attachment, which increased its capacity to 825 US tons (748 tonnes). It was configured with 103 metre boom.

Each sheave weighed between approximately 65 tons (58 tonnes) and 135 tons (122 tonnes). For the lifts of 75 tons (68 tonnes), the crawler worked at a radius of 18 m and was configured with a wheeled counterweight of 386 tons (350 tonnes). For the heaviest loads of 135.3 tons (122 tonnes), the crane lifted the loads at a radius of 46 m.

Mike Weaver, All Crane Rental of Florida special projects manager, said, “Planning the lifts alone took four weeks. We used All’s 3D Lift Plan software to simulate these lifts and come up with the ideal crane to use. We chose the Manitowoc 18000 for its efficiency and suitability for this project.”
