South Korean lifting company Chunjo Construction Co used its Manitowoc 31000 to help construct a petrochemical refinery in the Thanh Hoa Province, Vietnam.

The 2,300 tonne capacity lattice boom crawler has the Variable Position Counterweight (VPC) system. It was used to erect a range of heavy process equipment, including xylene columns, weighing up to 983 tonnes. The crawler was configured with 90 metres of boom and 964.11 tonnes of counterweight. It was set up on steel mats, as opposed to traditional timber mats, which lowered the ground-bearing pressure from 70 tonnes per square metre to only 30 tonnes per square metre, a spokesperson added.

Jong Seoung Park, Manitowoc Cranes general manager in Korea, said, “Though it is a challenge to transport such a large crane to another country, customers still wish to have the 31000 on their job sites because it saves so much money during shipping, ground preparation and erection. Also, the crane is gaining a reputation for excellent performance. Chunjo prefers the crane for these large lifts and the contractors are very pleased with the crane, too, because it reduces costs and completes their projects with greater efficiency.”

Park continued, “This was a great test to see how the crane would fare in being shipped to a country outside Korea, and all of the companies agreed it exceeded expectations. The crane not only completed the challenging lifts, it reduced costs and increased efficiency.”
