The combined advantages of versatility and mobility in its equipment fleet help Zignego Co. Inc. achieve a profitable level of productivity on its numerous urban, highway and interstate construction jobs. Recently, that included a major four-lane highway repair project on Highway 36 (Loomis Road) outside Milwaukee, Wis.
The company used a Gradall XL 4100 III to remove large sections of concrete after they had been saw-cut. High-pressure, load-sensing hydraulics provide excellent boom strength for the Series III model, allowing it to easily lift large sections weighing up to 10,000 lb.
As part of the overall highway upgrading effort, the Zignego crew also created several new turn lanes on the same section of highway, in addition to removing and replacing old curbs and gutters. Workers used the excavator to excavate and remove the old curbs and various other sections of concrete, and then re-grade those areas, including spreading dirt and finishing the surface before the new asphalt was poured.
