| BF6615 self-propelled asphalt paver  The new BF6615 self-propelled asphalt paver from BOMAG offers the power and capacity that commercial paving contractors need for larger, high-production paving projects. Weighing in at 20,500 pounds, the BF6615 features a 99-horsepower Cummins water-cooled diesel engine that is turbocharged for consistent power at all altitudes. The engine's ECO-mode feature saves fuel and reduces noise by automatically lowering rpm's during stops and pauses. At the same time, an exclusive load-sensing hydraulic system lowers fuel costs by delivering power only when needed.The new design, UNIMAT 2 full-width floating screed has a standard 8- to 15-foot paving width. The screed is electrically heated, eliminating the need to change propane bottles in the middle of a large project. Dual vibrators provide 2,500 vibrations per minute. The generous nine-ton hopper capacity on the BF6615 allows high-production paving to continue between trucks. Even with its power saving system, the new paver can push asphalt feeder trucks while maintaining working speeds up to 180 feet per minute. The BF6615 also features a crawler style track drive system undercarriage with standard bolt-on polyurethane track pads. Eight sealed rollers per side carry the weight of the machine, while bolt-on rock guards installed on the inside and outside of each track drive prevent asphalt from loading up on the chains. Each of the track drives is bolted to a cross member frame structure and can be removed individually for maintenance. The entire undercarriage structure can be removed as well. The screed on the BF6615 features two abrasion-resistant, extendable, reversible and independent hydraulic augers. Evenly distributing a uniform layer of asphalt across the mat, the two augers extend with the screed extensions, providing consistent material control at all paving widths and minimizing the need for hand labor. Screed extensions can be adjusted for a two-inch crown or invert. Screed wear plates are 3/8-inch thickness abrasion-resistant 400 Brinell hardened steel. Designed to withstand harsh job-site conditions, screed plates are bolted on for easy replacement. The BF6615 features dual operating positions for control from either side of the paver. The engine is positioned low in the machine, giving the operator outstanding visibility from either side. Engine shroud is standard for heat and noise reduction. Fail-safe brakes are also standard. Both the augers and dual hydraulic slat conveyors offer full automatic control with manual override. This allows the operator to precisely control the amount of material being sent to the screed if paving wider or thicker on one side or the other. Despite its high-production performance, the BF6615 is compact with a transport length of just 15 feet. Machine height is just 74 inches. For simple cleanup, the BF6615 features a hydraulically lifting bed and has all major components located outside the hopper. A standard fume extraction system helps reduce asphalt odor. Other standard equipment includes urethane track pads, a high engine water temperature/low engine oil pressure automatic shutdown, wash down spray system, swivel mounted bumper rollers and power depth adjustment controls for variable mat thickness. Optional equipment includes a swivel-mounted tow-type hydraulic truck hitch, working lights, ditch plates, simple Moba automatic joint matcher and Topcon screed automation system. write your comments about the article :: © 2008 Construction News :: home page |
