China’s Sinopec Heavy Lifting & TRANSPORTATION Company (SLT) has been subcontracted to work on the first phase of the Duqm Refinery and Petrochemicals Industries scheme.

The specialist heavy lifting contractor is using the XGC88000, world’s largest crawler crane, for the project.

Crawler cranes are cranes mounted on an undercarriage with a set of tracks, also known as crawlers, that allow it to move around.

The XGC88000 has already been used to lift a diesel hydrogenation reactor, weighing 808t, into place as part of the EPC 1 package, according to a statement released by SLT.

The diesel hydrogenation reactor is 45.7m-tall.

In a statement, Sinopec said that there are totally 107 pieces of heavy equipment for Duqm Refinery EPC 1 package, of which 15 super-heavy pieces will be lifted by the XGC88000.
