Shelly and Sands, Inc. started paving the new South runway at the Columbus Airport project Monday, the 16th of April 2012. They are shown utilizing two Vogele vision series 5200-2 pavers. They are paving 25 feet wide in echelon and they are utilizing the latest in the state of the art screed automation from Vogele, Dual NEVELTRONICS big skis set up to 47 feet long. They are using two skis per paver to do longitudinal averaging, allowing the second pavers ski to overlap the first paver’s pass getting great averaging over the 50’ section.
Behind one paver they are shown utilizing the newly designed low profile Hamm GRW280 30 ton pneumatic tired roller as breakdown compactor along with the Hamm HD130HV 84” vibratory and newly designed Hamm HD120+OV 78” oscillatory nondestructive compactor as finish roller on the P401 base mix being laid at a depth of 4+- inches and are getting perfect density results. Paving in echelon allows the center joint to be considered as a full mat without having to meet the stringent longitudinal density requirements of the FAA. Behind the second paver is Type 1 Pneumatic roller and a newly designed Hamm HD110+VVHH high frequency vibratory roller followed up by Hamm HD120OV oscillatory roller…
McLean Company and VT Leeboy Customer Race Day
By · CommentsWell in spite of a very rainy September 23, (Friday) the 2011 ADRL sanctioned race at Summit Raceway Park in Norwalk, Ohio was very successful for The McLean Company’s annual customer appreciation day. Quain Stott racing qualified with his 1963 Pro Extreme Chevrolet Corvette with an almost 200 mph 3.72 times in the 1/8 mile track. Due to the rain on Friday no qualifying runs took place that day so Saturday they were limited to two runs. Quain got his qualifying on his first run. He had problems with tire shake the rest of the day even when the real racing began he had a great start but had to let go of the throttle to keep the car from tearing itself apart and was then eliminated. Quain was as always the fan friendly host and took care of the 100+ customers through the pit area. Lunch was served and beverages provided for still a very fun day of racing. Thanks again to VT Lee Boy for bringing Quain Stott racing back to Norwalk, Ohio.

Kokosing Construction with Wirtgen W210
By · CommentsKokosing 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.
