Contractors World International Vol 7 No 5
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 produc-
tion 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 han-
dling 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
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 en-
gine and is driven by a four-speed Powershift
