Mammoet has performed its largest lift for Lotte Chemical’s ethylene glycol project in Louisiana, USA. In late September, Mammoet used the PTC 200 DS – the largest crane in its fleet – to lift the 350 foot (107 metre) long, 3.5 million pound (1,600 tonne) wash tower.

The head section was hoisted out of the saddle with the crane while the rear section was simultaneously lifted out of the saddle, aided by 60 axle lines of self propelled modular transporter (SPMT) with a tail frame. Once the wash tower was fully erected, the vessel travelled 442 feet (135 metres) to its foundation. The entire process took 3.5 hours.

The lift was on a tight schedule resulting from severe weather delays. With the lift complete, the crane will be reconfigured, adding another 220 feet (67 m). This will bring the total reach of the PTC to 713 feet (217 m), almost two-and-a-half times as tall as The Statue of Liberty.
