Big Enough to Fit a Dozer with the Blade Up
In Superior, Wisconsin, where the St. Louis River meets Lake Superior, there's a maintenance shop on an 80-acre coal yard. The bulldozers that work the yard come in here for service. They push coal across the piles and feed the conveyors that load the lake freighters headed for power plants downstream.
Mike Lebsack ran the project for Midwest Energy Resources Company, a wholly owned subsidiary of DTE Energy. The shop needed a door big enough to fit a dozer with the blade up and to run dependably day after day. The shipping season's short and intense, since the port closes for ice about four months a year, and any downtime with bulldozers costs real money.
“Without a doubt, we are super impressed with the quality of construction of the Schweiss bifold door. It's very pleasing to the eye, and all the welds are really good. Schweiss sent a team out to verify measurements before we actually ordered up the door to make sure measurements were spot on. Installation went super smooth — The Schweiss installers were very easy to work with. Rick and Rich have obvious pride in your company, product, and their work.“
