Blastrac developed the new BMR 85D Multi-Task Rider with a 20-inch-wide shot blasting pattern and 12-inch scarifying head. The company says its closed-circuit, dust-free unit is effective preparing bridge deck surfaces, airport runways, parking decks and roadways. The continuous waste-disposal system contains all dust in heavy-duty impermeable bags. Other options being developed for the four-wheel-drive unit include rotary sweepers, mowers, snow plows and blowers, as well as dump trailers. MSRP on the unit is $225,000.
