The low-profile LP 533/833 SGT (super gas trailer) hydroexcavator from Vac-Tron Equipment is powered by a 37 hp Kohler gasoline engine with 1,000 cfm vacuum pump.
Similar to the pre-Tier 4 Final SDT diesel model with 1,000 cfm vacuum pump, the gasoline version features the Series 33 hydraulic rear door that opens to a 90-degree angle and is equipped with an automatic safety lock.
“We design and build our own trailers,” says Brian Showley, vice president, sales, Vac-Tron. “It’s built with a low center of gravity for safety and towing, as
well as ease of operation in the field. Everything is accessible from the ground.”
The trailers are built on a heavy I-beam frame with Dexter torsion axles and Goodyear tires. Overbuilt for safety, the trailers are equipped with a 500-or 800-gallon debris tank, up to 400 gallons of water and a high- pressure pump capable of 3,000 psi at 4 gpm. They are available with a GVWR less than 10,000 pounds to 24,000 pounds.
“It’s a smaller version of your large trucks,” Showley says. “It’ll do many of the same jobs, only on a smaller scale and at a much lower cost.”
Applications include utility locating; slurry removal; manhole, lift station, storm drain, meter box, valve box and retention pool clean-out; street sign installation; non-hazardous spill cleanup; micro-tunneling; and resetting tombstones.
“One of the main components that sets our equipment apart is the filtration,” Showley says. “When you’re doing vacuum excavation, your filter system is what protects your vacuum pump. You’re sending debris into the debris tank, but then you have airborne particulates, grit and pieces of rock that can come out of the debris tank and pass through your vacuum pump, causing damage to your pump, unless the filter protects it.”
Vac-Tron’s CVS filtration housing has a 28-inch-diameter cyclone, four-way valve for reverse pressure, silencer for quiet operation and a 0.5-micron washable filter that can be removed and cleaned from ground level. Options include the six-way hydraulic boom with wireless remote and 15-foot strong arm that supports the weight of the hose for one-person operation. 888/822-8766; www.vactron.com
