Loader Power For New Quarry As Demand Increases
Scott Construction Inc., Lake Delton, is one of Wisconsin’s leading asphalt surfacing companies, and the largest chip seal contractor in the state. To support the amount of chip seal work the company performs throughout Wisconsin and Minnesota (regional suppliers couldn’t keep up with the demand), the company began mining granite out of the new Pine Valley Quarry (Neillsville, Wis.) in 2015.
With the new quarry, Scott Construction can control quality and access to its chip seal products. The company shoots raw granite and crushes it down to <16 mm (5/8-inch), and then screens it and crushes it down again to <12 mm (½-inch). The company then washes that and further crushes it down to <10 mm (3/8-inch) and <6 mm (¼-inch) product. The remaining byproduct is then used for hot mix and concrete.
The company is able to load upwards of 150 trucks/day, depending on the output or demand.
Rapid Production Increase
By early June 2016, the company had tripled its production out of the quarry compared to all of 2015. Much of that workload is performed on the shoulders of its wheel loaders.
The company uses both a Case 721F wheel loader and a Case 821E wheel loader in the Masaba crushing stages of production.
From there, a Case 1021F wheel loader takes over and handles the bulk of truck loading and material handling activities. Over time, the 1021F wheel loader has become the most important machine in the pit.
Steve White, operator, Scott Construction. says:
The 1021F is the key piece in everything that’s going here. It’s irreplaceable. The 1021F has been the heart of our operation here.
The Power of Speed and Fuel Efficiency
Scott Construction handles 350 tons of granite each hour over the course of a 14-hour day.
Daily tonnage often exceeds 4,000. With such a heavy workload – Scott Construction worked with Wisconsin dealer Miller-Bradford & Risberg to equip the site with a high-capacity wheel loader that would combine speed, power and fuel efficiency.
The 1021F is powered by a 296 horsepower FPT engine and is driven by a four-speed Powershift transmission with heavy-duty axles with a locking front differential.
