LeeBoy 9000 Rubber Tire Paver Built for Production on Large Commercial Applications
LINCOLNTON, N.C. – At CONEXPO, VT LeeBoy, Inc. introduced its 9000 Asphalt Paver, a 33,000-pound paver featuring a maneuverable, rubber tire design and an 8-foot electrically-heated screed system.
This high production rubber tire asphalt paver is powered by a 173-HP CAT Tier 3 diesel engine, which provides the power to push larger tandem axle trucks with ease. The engine is transversely mounted, which allows for better ground level access and cooling efficiency. A fume ventilation system vents asphalt vapors away from the operator and screed area. Two Series 90 variable displacement pumps drive paver functions. An easily raised hood covers the low profile engine and side grating is easily removed to provide access to the engine compartment.
The LeeBoy 9000 operator stations are designed for maximum comfort and ease of operation. It includes dual hydraulic slide-out operator stations to enhance fore and aft visibility with fully equipped consoles that incorporate CAN Bus system design and digital gauges for monitoring paver functions and diagnostics. Paver steering is by Plus 1 control architecture with touch pads.
The 9000 rubber tired paver provides excellent maneuverability, ground speed, ride quality and traction. The tire system is comprised of two large heavy-duty low pressure rear 19” x 29.5” drive tires. The 12 x 22 inch solid rubber front tandem steering bogie wheels oscillate to improve mat quality by overriding roadbed irregularities.
The material handling system on a 9000 paver begins with an 11-ton receiving hopper with heavy-duty, hydraulic radius hopper wings and high strength plastic flashing to prevent material spillage. Dual 18” heavy-duty slat bar and roller chain conveyors feed the 16” diameter hardened cast steel augers that push asphalt to the screed. The auger assembly can be hydraulically raised and lowered, which is helpful in the loading and unloading process. Standard sonic feed sensors control the augers. The operator has independent left and right control of the conveyor system and material flow gates. Manual tunnel extensions are available to keep mix away from the drive tire.
The 9000 paver has a heavy-duty electrically heated and vibrating Legend Screed System that extends hydraulically from 8- to 15.5-feet. An onboard 20 Kw generator electrically heats the main screed and the front-mounted extensions. LeeBoy’s exclusive heat element replacement system makes replacing heating components easy. Adjustable screed extensions feature a 9 degree slope.
A two-speed motor with single reduction planetary torque hub allows the 9000 paver to travel at speeds up to 13 mph. The 9000 paver can pave at speeds up to 250 fpm.
Fluid capacities are among the largest for this size paver with an 82-gallon fuel tank, 86-gallon hydraulic oil capacity and 15-gallon citrus washdown tank.

Wirtgen America Inc. will exhibit the new W 120 F at Conexpo-Con/Agg 2008 in Las Vegas in March.
Part of a new line of midsized mills, the W 120 F is a high-performance cold milling machine with a drum width of 48 inches (120 cm), ideal for removing complete asphalt courses with a milling depth of 0 to 12.6 inches (0 to 320 mm). Its engine output is 304 hp, and it replaces the W 1200 F/T in the product line.
The W 120 F has a hydraulic swinging track for flush cutting, and features front-end loading of reclaimed asphalt pavement (RAP) via a two-part conveyor system. The machine is available in a tracked version but can be ordered in a wheeled version.
The optional Flexible Cutter System (FCS) permits the use of different milling drums with working widths of up to 48 in. and a variety of line spacings. And the W 120 F will be equipped with the new Wirtgen Level Pro® leveling system.
Wirtgen also will exhibit the new WR 2000 XL recycler/stabilizer, with a 94-in. cutting drum and 425 hp engine.
Ambry Asphalt Interview With LeeBoy
Posted by: | CommentsNo one likes to be a guinea pig. And that’s what Matt Ambrose, owner of Ambry Asphalt in Mansfield, Ohio, felt like when he tried to lay asphalt with a competitor’s paver. According to Ambrose, “The [competitor’s paver] didn’t want to track straight. The motor was mounted in a bad place and vibrated so bad that we snapped the exhaust manifold just trying to track down the road. The screed was loose and didn’t respond well. It was hard to load. The truck hinges snapped off. We were fighting it a lot.” Ambrose says he didn’t want to go through the growing pains of this new product. He adds, “Although I’d used the [competitor’s large] equipment with good results, I just didn’t get a good feeling about the smaller paver.” On top of that, Ambry did not have access to parts or service. The competitor didn’t have it together on this paver.
Ambrose needed a dependable paver for the driveways and lots that are his usual jobs. He decided to look at the LeeBoy 8000 D Track Conveyor Paver with McLean Co. in Columbus, Ohio. Ambrose gets excited talking about his 8000 D. “The material controls and gate shut off are great. It drives straight, and I like using the sonic auger controls. It’s not too loud. I like the propane burners. It starts well on a cold day. It stops where I want it to. We don’t have piles to shovel or sweep. It loads beautifully, drives straight and doesn’t pull.” But the most important feature to Ambrose is the material control. “It’s a big deal in commercial lots,” says Ambrose. Commercial lots have many turns and are too large to spend time cleaning up after bad stops and starts.”
Ambrose adds, “The LeeBoy [paver] cost more. But it was worth it. Buying it was the best decision I’ve ever made. I’m very impressed with this machine.”
