Manitowoc 31000 performs heaviest lift yet

Manitowoc’s largest ever crane has completed its largest ever lift, hauling a 650-tonne cold box.

The Manitowoc 31000, a 2,300-tonne (2,535-ton) capacity crawler crane, performed the pick-and-carry lift at a liquefied natural gas plant in Gwangyang, South Korea.

The Manitowoc 31000 lifted the 55 m tall cold box, which measures 9 m by 9 m, off a flatbed trailer in tandem with a 600-tonne capacity Manitowoc 18000. Once airborne and upright, the 31000 took over and carried the load to its final location. The entire operation took less than two hours.

The recent took place in September at the Posco E&C plant where the crane, which is the first 31000 in the field, has been working since March.

Even heavier lifts are in the pipeline, with a 900-tonne lift scheduled for this month and two 1,000-tonne lifts slated for December and February.

The 31000’s design means it can be disassembled, moved and re-assembled in just four weeks. As a result, it has a busy schedule.

Crane rental firm Chunjo Construction of South Korea owns both the Manitowoc 31000 and the 18000.
