Grove RT765E-2 Relocates Historic Viking Ship | Construction News

A Grove RT765E-2 rough-terrain crane has relocated an 87-year-old exact replica of a Viking ship in Duluth, Minn. The ship was located in a park that sits directly over an interstate. With strict size and weight limitations, uneven terrain, and an irreplaceable load, the 65-ton capacity crane had much to contend with. But the complex project was completed successfully – and at no cost.

Wisconsin-based Viant Crane supplied the RT76E5-2 to the complex project. After funding fell through, Viant was pleased to overcome the many challenges of the unique project at no charge, as Nick Minardi, director of operations, explains:

“We believe in giving back to the community and we didn’t want to see this project canceled because of lack of funding,” Minardi said. “We chose the Grove RT765E-2 for the job because we knew that Grove cranes give you smooth, constant operation and controls that are immediately responsive. We were confident that our operator would feel comfortable and be in total control of this fragile load.”

The RT76E5-2 lifted the 4.65-ton vessel three times. First, the ship was raised 65 ft. into the air so it could be swung 180° over nearby trees to avoid damaging them. Then, it was placed onto a light pickup trailer to keep the total weight within the park’s limits before being moved about 600 yards. Finally, the ship was lifted onto a third trailer that met highway weight and clearance regulations.

Because the park sits on top of Interstate 35, Viant had to use a crane that fit within the park’s 11-ft. wide boardwalk. Viant initially planned to use an 80-ton crane from its fleet, but its footprint was too large. So, the company bought a new RT765E-2, which measures only 10'6" wide and fit within the park’s weight limit.

Grove’s RT765E-2 offers a 110-ft., four-section, full-power, Megaform boom, which easily handled the 4.65-ton ship. It’s an extremely mobile crane with four-wheel, multi-mode steering and Full Vision cab – all of which helped Viant’s crane operator navigate the tight job site.

In all, the complicated endeavor was a complete success, thanks to months of careful planning and precision picks from experienced operators.
