In Canada, department of transportation regulations limit the amount of payload a hydroexcavation truck can haul on public roads. To follow those guidelines, while maximizing payload potential, Supervac designed the Atlas trailer hydroexcavation.
“Increased payload is the key to the efficiency of this unit,” says Réjean Lachance, Supervac’s general manager. “It is only 2 ft longer – including chassis – than your typical hydroexcavation truck, and allows you to carry more than double the payload.”
At 31.5 ft, the trailer offers the compact versatility of a regular vacuum truck, with a high payload capacity of 49,400 lbs. Exclusive design and equipment combined with accurate weight distribution result in a piece of equipment with no match in the industry.
“That makes it a great fit for urban areas,” says Lachance. “It is very easy to maneuver with its tight turning radius and solves road weight limit issues. Those laws are very strict in Canada and are becoming more so in the United States. You have to respect the law.”
The Atlas comes equipped with a flashing arrow and LED working light, full-opening rear door, protection arm and LED light, a hydraulic door lock, 3,600-gallon carbon steel debris tank and baffle, and a catwalk access ladder and handrail. Its six side-mounted and evenly distributed plastic water tanks (three on each side) have a total capacity of 1,500 gallons.
“This is the first time on a hydroexcavation trailer where the tanks are evenly distributed on each side,” says Lachance. “That makes for an easier, safer ride for the unit as a whole.”
One of the biggest improvements the unit brings is its lack of a pony engine. Instead, Supervac has designed the unit to run off the chassis engine of the tractor being used to haul the trailer. We just figured there was no reason not to use the power of the truck you have there. Not having a pony engine saves on initial equipment expense.
The unit’s top-loading boom offers 320-degree rotation, extension of 25 ft, an 8-in. flex hose, top access door, and protection elbow. The debris tank has a 20-in. manhole for access and cleaning, a primary shutoff valve, 14-in. stainless steel floatball, a 6-in. vacuum relief valve, carbon steel cyclone and dropbox. A fully insulated enclosure houses a Webasto diesel heater for work in cold climates. The unit’s Pratissoli water pump offers 20 gpm capacity at 3,000 psi. The unit comes equipped with hose reel with a capacity of 100 ft of half-inch hose, with a gun/lance system and 12-volt recirculation pump. Its Dynablast boiler offers 680,000 Btu, while its heavy-duty Robuschi blower offers 3,800 cfm at 27 in. Hg with hydrostatic drive.
