Westech Vac Systems, a leading provider of rugged, high-quality vacuum truck-mounted solutions, has introduced the compact Coyote hydrovac for utility, municipal and contractor customers in Canada. The mid-sized unit was designed as an ideal option for customers working in urban and metro environments who need maximized legal payloads and who value a rugged and durable hydrovac truck that can easily maneuver in tight, confined spaces without compromising productivity, performance or legal payload.
“The hydrovac industry has changed drastically. Vacuum excavation customers are looking for a broader range of hydrovac solutions with varying vehicle sizes, axle capacities and chassis configurations,” said Ben Schmitt, general manager of Westech Vac Systems. “Today, the key to success in the industry is maximizing payload capacity, which equates to on-time productivity and happier, more profitable customers. The introduction of the compact Coyote hydrovac is a great example of our commitment to developing the kind of rugged and durable vacuum excavators Westech is known for, while also complying with weight regulations and maximizing legal payload and productivity.”
Smaller size, enhanced maneuverability
A mid-sized alternative to the larger Westech Wolf hydrovac introduced in 2017, the Westech Coyote delivers big advantages in terms of maneuverability and stability. “The Coyote is almost seven feet shorter than our popular Westech Wolf hydrovac,” Schmitt said. “Combined with a tandem axle drive, the Coyote’s maneuverability in tight urban areas is significantly enhanced.”
“The Coyote is designed with a 6-in. vacuum system and high air-flow capabilities to maximize performance,” Schmitt said. The hydrovac features a six-inch hose—which reduces hose clogging frequently found on smaller vacuum systems—and a powerful vacuum system capable of up to 3,200 CFM and 16″ Hg of vacuum. The larger hose and vacuum system make the Coyote a more productive vacuum excavator than other similarly-sized units.
Schmitt added that the Westech Coyote comes standard with a hydraulically driven blower system which simplifies the engagement process when moving from hole to hole on quick locating applications.
Improved weight distribution
“Like the full-sized Westech Wolf hydrovac, the Coyote was designed to constantly maintain the centerline for the water tank and debris body,” Schmitt said. “As water is reduced and debris is loaded, the weight increases on the individual axles equally.”
The Coyote’s debris body is positioned on the optimal spot of the chassis to ensure the payload is proportionately distributed across all axles simultaneously. “The goal with Westech hydrovac trucks is to efficiently use as much axle capacity as possible, while keeping the design safe and productive, resulting in more time on the job and a reduced risk of overweight penalties,” Schmitt said.
The Westech Coyote features classic hydraulic and electrical systems and a more traditional design for simplified field troubleshooting and repair. “Our customers expect a piece of equipment that is built to last; but if and when there’s an issue, they can quickly and easily fix it in the field,” Schmitt said. “Westech equipment works in some of the most remote locations in North America, where parts and service availability are virtually nonexistent. Being able to get up and running quickly is paramount.”
The Coyote can be upgraded to a 20 GPM @ 3,000 psi water pump, with water heater options up to 980,000 BTU’s for extreme winter conditions. An optional steam-cleaning kit is available for cleaning sludge, grime and grease from traps and pits.
