Patch removal for subgrade re-stabilization work needs to be handled as quickly and productively as possible, and K-5 Construction Co. relies on its Model XL 4100 Gradall excavator to efficiently meet that challenge on many different sites in the Chicago area. On a typical jobsite, the pavement to be removed is cut in increments of about 6 feet by 20 feet. Care is taken to make sure the patch removal process does not disturb the finished, untouched portion. Efficient rebar installation is important, and the ability to move from one patch removal site to another very quickly is also needed.
The Model XL 4100 Gradall excavator is equipped with a wheeled undercarriage that can be driven from one job to another at highway speeds, without the need or expense of a lowboy trailer. Once they're working on jobsites, Gradall excavators can be efficiently repositioned from the upper operator cab. The Model XL 4100 acquired by K-5 from Finkbiner Equipment is equipped with a 40-inch pavement removal bucket and a 24-inch curb removal bucket. Unlike boom-end tilting mechanisms, the entire Gradall boom tilts to properly position attachments without reducing boom strength. With superior power and more precise attachment positioning, the Gradall excavator can quickly and carefully remove the patch and curb without damaging unaffected areas. Then, using a "Minnich drill" attachment, the Gradall boom can achieve the position necessary to create holes for rebar. "For pulling patch," said Andy Bazan, vice president of sales for Finkbiner, "the Gradall is the only way to go."
