Kokosing Construction Company recently purchased the latest in the state of the art of milling machines from The McLean Company. Kokosing purchased a Wirtgen W210 dual engine machine this past winter and put it to work this spring at the Cleveland Hopkins airport. This will make 5 Wirtgen machines that Kokosing has purchased from The McLean Company.
At Cleveland Hopkins airport they are shown milling a taxi-way. The first pass they milled was up to 9″ deep 72” wide and was milling an average of 36′ per minute. The second pass being a little harder aggregate they milled at 8.5″ depth and averaged 32′ per minute. They were very pleased with the production of the machine.
One unique feature is this W210 is designed with 2 engines and the onboard computer systems can determine the engine output for simple maneuvering and traveling. It may only require one engine in use; however as the demand for HP increases for milling applications the computer will put the second engine into action. This is a considerable fuel savings instead of running one higher HP engine at higher rpm’s all the time. Fuel savings can range up to 20-30% over the conventional drive train. The engine can run in 3 different work ranges manually. Kokosing opted to run it in the medium setting, which is 1800 rpm. Economy setting is 1600 rpm and high setting is 2100 rpm. They felt they got their best production at that setting.
Wirtgen’s exclusive Level Pro Multi-Plex non contact averaging system was utilized during the asphalt removal for more accuracy for profilograph requirements on smoothness asphalt paving. For more on the W210 and Level-Pro and for Kokosing Construction, see the attached link.
