Road Widener is offering a spray bar system that increases the versatility of its patented offset vibratory roller attachment. This accessory fits on all offset vibratory roller attachments and aids in suppressing dust particles, compacting aggregates and preventing clumping when rolling hot mix asphalt. It can be easily attached to the offset vibratory roller, a compaction attachment that allows the host machine to drive safely on flat ground while compacting shoulders, ditches, trenches and other hard-to-reach areas alongside the road. The spray bar system will allow contractors to increase efficiency and versatility when compacting a variety of materials including asphalt, stone, gravel and topsoil.
Lynn Marsh, president, Road Widener, says: “We knew the attachment was capable of many forms of compaction, but it was not until the product reached our customers that we realized its full potential. We listened to their feedback and designed a spray bar system that heightens the capabilities of this already one-of-a-kind product.”
The offset vibratory roller offers contractors safety over self-propelled compaction machines that have a greater risk of tipping. The attachment’s offset, patented design allows the host machine to drive safely on flat ground while compacting sloping shoulders, ditches, trenches and other hard-to-reach areas alongside the road. These are tasks that have traditionally put road crews in danger of rollover accidents, increased workers’ comp costs and led to poor safety ratings.
“The United States Department of Transportation’s Road to Zero Deaths initiative is a program we feel strongly about,” says Marsh. “We’ve worked in the road construction industry and know first-hand the challenges and dangers crewmembers are up against each day. This led us to engineer a solution to heighten safety with an offset design. We believe that our offset vibratory roller will help achieve the goal of ‘Moving to Zero’ because it truly offers incomparable compaction safety.”
The spray bar system comes with two seven-gallon tanks for each side of the roller and can pair with any-sized water tank that may already be on the host machine. These features all complement the offset vibratory roller that has a total reach of nine feet and can be purchased with a two-, three- or four-foot-wide drum. The drums can pivot up to 30 degrees, reach up to 30 inches below the mounting point, and are interchangeable. This allows road crews to take on jobs of varying sizes and aggregates by purchasing additional drums instead of investing in multiple self-propelled machines with engines that can fail. Additionally, the vibratory feature operates between 2,500–3,500 vibrations per minute for optimal compaction.
The offset vibratory roller attaches to any host loader, skid steer, compact track loader or road grader by inserting the host machine’s lift arm pads into the offset vibratory roller’s universal mounting pad. An adapter plate is also available for host machines like compact backhoes and telescopic loaders that may not be readily setup to accept standard attachments. It is compatible with standard and high flow hydraulics. The attachment operates without an engine, powertrain, or any associated parts of its own, which makes for less maintenance than self-propelled machines while also reducing labour.
