Heavy lift, transport and installation specialist Roll Group made two lifts, each of more than 1,000 tonnes, at a petrochemical plant in Cilegon, Indonesia.

It used its new RMG modular gantry crane equipment for both lifts. The work was part of Roll Group’s combined scope, also using its fleet of self propelled modular transporter (SPMT) and cranes.

To move the C3 lower splitter column prior to uprighting Roll Group used two sets of 24 axle lines of SPMT, one set under each end of the column. It was 79.6 metres long by 9.36 metres wide and 9.95 metres tall. Weight was 1,042.7 tonnes. The 2400Te gantry system was erected to a total height of 97 metres. As the gantry system uprighted the C3 column it was tailed by a 1,250 tonne capacity Terex / Demag CC 6800 crawler crane, a model now designated Tadano CC 68.1250-1.

Implementation of the new heavy gantry crane system on this job proved the ability to install heavy loads Roll Group said. The system can handle loads weighing as much as 3,000 tonnes, lifting to to heights exceeding 120 metres. A distinguishing feature of this system is that it can operate without needing guy lines, thereby minimising disruption to the surrounding area, increasing efficiency and occupying minimal space.

Further scope

In addition to the gantry lifts, Roll Group’s scope included discharging vessels, transporting all cargo and lifting it into position. It meant the company offered the total solution, including engineering, project management, SPMT and five crawler cranes.

The heavy gantry crane system proved itself on these two lifts and two more made in the Middle East, where it will stay for the next two years.

Demand is such for the new gantry system, Roll Group has started fabricating another one, ready to go to work by the end of 2024. This one will boast “enhanced capacity and capabilities, ensuring Roll Group remains at the forefront of the evolving market landscape,” the company said.
