Alatas US carried out an extensive crane modernization project that demonstrated our multi-service capabilities, from engineering, manufacturing, workshop repairs, and field services. With our proven knowledge and expertise in crance design, manufacturing and onside modifications, a client chose Alatas USA to extend the jib of their Goodcrane offshore deck crane for a specific contract and provide a complete pedestal.

Overview of the project

Our in-house design team began the project by designing the jib extension and the new pedestal with a new winch that was to be added to the wire rope was specified. Next, Alatas US manufactured the new jib section while a partner fabricated the pedestal, with Alatas on top of quality control throughout the process. 

After manufacturing, it was over to our field service team, whose first job was to remove the existing jib section before installing the newly manufactured jib. After the field service team introduced all new components, testing, start-up and commissioning were carried out.
