Mammoet’s biggest crane performs lifts in Louisiana

Mammoet has mobilized its biggest crane, the PTC 200 DS for Lotte Chemical’s Ethylene Glycol project in Louisiana, USA.

The gigantic crane was used to lift a 350ft-long wash tower, weighing over 3.5m pound (1,600t).

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 SPMT with a tail frame.

Once the wash tower was fully erected, the vessel traveled 442ft (135m) to its foundation. The entire process took 3.5 hours.

With this lift complete, the crane will be reconfigured adding another 220ft (67m). This will bring the total reach of the PTC to 713ft (217m), just under two-and-a-half times as tall as The Statue of Liberty.

“This will significantly contribute to project efficiency as it allows the crane to remain in its current location while still being able to reach modules located further away,” said Mammoet.
