Wren Works used a Manitowoc 11000-1 crawler crane to help build a retaining wall at the Mont du Lac Resort, a skiing destination in Superior, Wis. Rigged with 140 ft. of boom, the 110-USt crane lifted an 18.5-USt pile hammer to heights of 75 ft. to drive 14 H-piles. Gangs of timber that weighed 0.5 USt were then lifted to a height of 60 ft. and inserted between the piles to create a foundation for the retaining wall that will eventually shore up the resort’s new banquet room.
“We’re working on a 25% grade for this project, so we needed a crane that had the power to traverse the job site,” explained Brook Benes, president of the Poplar, Wis. company. “The 11000-1 had plenty of power to drive the tracks up to the top of the hill, and the crane’s capacity and easy set-up helped us to keep construction on schedule.”
Hayden-Murphy Equipment, Minneapolis, Minn., rented the crane to Wren Works for the project, which was completed in November of 2016.
