| Redesigned BF814 and BF815 pavers from BOMAG  The redesigned BF814 and BF815 pavers from BOMAG now feature a low-profile engine hood for improved operator visibility. Both the engine and hood have been lowered six inches to give the operator a better view of both sides of the machine. Built with UNIMAT 2 screed assemblies, the BF814 and BF815 offer 8- to 14-foot and 8- to 15-foot standard paving widths, respectively. The new pavers are able to handle a wide variety of applications - from paving secondary roads and city streets to small asphalt repair and resurfacing jobs. Additionally, the screed extensions are hydraulically controlled, allowing operators to change paving widths "on-the-go" within the entire paving range.Though primarily intended for commercial paving jobs, BF814 and BF815 offer mainline paver performance and features. Powered by 85-horsepower, water-cooled Cummins turbo diesel engines, the BF814 and BF815 offer production not typically found with comparable-class pavers. Combined with an exclusive load-sensing hydraulic system that delivers power only when needed, the pavers can maintain impressive paving speeds up to 180 feet per minute and travel speeds up to 360 feet per minute, all while remaining highly fuel efficient. The screed design on the BF814 and BF815 utilizes a formed leading edge that maximizes material flow and makes it possible to pave at depths ranging from 0 to 6 inches. The screed can be crowned or inverted up to 2 inches for maximum paving control, and is equipped with a vibrator and propane heaters to assure consistent material flow. Hydraulic depth controls and urethane track pads are also standard. For further material flow consistency, the screed extensions are fitted with material augers. Designed to provide steady and reliable material delivery at all paving widths, the augers are reversible and can be controlled automatically or manually. Both pavers features a low-deck configuration with dual operator's stations to simplify control and increase visibility. They can be operated from either side of the platform, or both at the same time. Additionally, machine controls are laid out for maximum operator comfort and ease of use. Featuring 8-ton capacity dual-slat conveyor systems, the hoppers on the BF814 and BF815 can be raised more than 6-feet high for complete access to the crawler system undercarriage. This simplifies required maintenance and cleaning, while allowing for conveyor and track-chain adjustment without having to crawl underneath the paver. New service entry points make for easy access to the paver's engine. Maintenance concerns are also reduced with the addition of track fenders as standard equipment. By keeping the tracks clean, the fenders help reduce excess wear to the track assembly. The tracks are self-cleaning with sealed rollers, while both the drive and idler sprockets are heat treated to prevent wear. Furthermore, screed wear plates on both the main screed and extensions are constructed of heavy-duty, abrasion-resistant 400 brinell hardness steel, which bolt-on for easy replacement. The BF814 and BF815 are available with Topcon's System Five Screed Automation. Using a "non-contacting" sonic sensor system, Screed Automation allows for paving without cumbersome skis or string lines and provides joint matching without actually contacting any surfaces. Other optional equipment includes a swivel-mounted hydraulic tow-type truck hitch with bumper rollers, ditch plates, fail-safe brakes, working lights and a simple Moba automatic joint matcher system. The Moba system controls mat depth automatically by way of a sonic sensor, eliminating the need for manual control. write your comments about the article :: © 2008 Construction News :: home page |
