R. W. Dunteman Co. is a third-generation general contractor, handling highway maintenance as well as airport runway repairs and general excavation around Chicago going back to 1927. Performing today's highway work efficiently, with only minimal traffic flow interruption, is critical on many jobs including an eight-mile section of I-294 west of Chicago.

GRADALL VERSATILITY ADVANTAGES

"On the I-294 project, I am able to repair 40 to 60 patches a night with an XL 4100 IV model," said Rick Turner, who has operated Gradall excavators on Dunteman jobs for 18 years. "This machine is much more productive. I used to repair 30 to 40 patches a night with an XL 4100 II model."

Using a pavement removal bucket and the power of the full-tilting boom, Turner expects that on the I-294 project, he will pull a total of 1,200 patches, mostly 12-inch thick concrete but also some asphalt. Full-tilting boom power helps him remove pieces of concrete more efficiently, working from many angles, without giving up power like he would if he was using a conventional boom-end tilting attachment.

"But this machine can handle more," he said. "A couple weeks ago, we pulled patch with 14-inch concrete. At another site, in six hours, we placed 3,000 feet of barriers, each weighing about 6,000 pounds."

Turner noted that the XL 4100 IV tail swing, which is 12 inches shorter than the XL 4100 II model, makes it possible to work in traffic without closing extra lanes. "We can work right next to the traffic," said Turner. "The shorter swing lets us keep an extra lane open, and that’s really important on I-294, which is a main highway in and out of Chicago."

He also had praise for the mobility of the new model, which he routinely drives from the equipment yard to the job every day.

"I really love the new automatic transmission," he said. "It goes faster up inclines. It moves through about anything. And the higher speed top-end speed (60 mph) makes a difference when you’re driving 30 miles to the job."
