Gradall excavators provided the ideal solution for the need to quickly install and later remove Jersey barriers along busy highway construction zones. The sooner the barriers can be installed and traffic diverted, the sooner the work can begin. And when the job is completed, there is an urgency to remove the barriers to restore normal traffic flow as soon as possible. United Highway Technologies, a division of United Rentals, operates three Gradall excavators with highway speed undercarriages that are used exclusively for setting Jersey barriers. Two Model XL 4100 excavators and one Model XL 5100 excavator are busy virtually every day, either placing or removing barriers in Pennsylvania, Ohio, West Virginia and Maryland.
Each of the Gradall excavators is equipped with a Kenco scissors attachment specifically designed to lift barriers. Working along a section of I-79 north of Pittsburgh, the Model XL 4100 was able to easily move 12-foot-long barriers weighing 6,350 pounds. "We can set about 8,000 feet of barriers in about 12 hours," said Scott Shaffer, job superintendent. "And we can pick up and load a mile of barriers in an 8-hour shift. That's something we couldn't do with a knuckle boom machine." Gradall excavators perform the barrier placement and removal process very smoothly, lifting and telescoping the barrier into precise positions, Shaffer said. Knuckle boom machines, he added, require five or six movements to lift and place barriers - a process that takes longer and is not as smooth. United Highway Technologies typically leaves its Gradall excavators on the jobsite overnight and between shifts. The ability to travel at highway speeds to and from jobsites is another advantage. Exceptional highway mobility allows companies to return excavators to the security of their equipment yards when not in use.
