Westech Vac Systems introduces the Coyote Hydrovac


Westech Vac Systems has introduced the compact Coyote hydrovac in Canada.

The mid-sized unit was designed as an option for customers working in urban and metro environments that need maximized legal payloads from a hydrovac truck that can easily maneuver in confined spaces.

“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.”

Mid-size alternative

A mid-sized alternative to the larger Westech Wolf hydrovac, the Coyote delivers 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 15-cm vacuum system and high air-flow capabilities to maximize performance.

The hydrovac features a 15-cm hose, which reduces hose clogging frequently found on smaller vacuum systems, as well as a vacuum system capable of up to 3,200 cfm and 16 Hg of vacuum.

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.

As well, the Coyote delivers a legal payload of 9,072 kg of spoils, varying by region, chassis and options ordered.

“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.

Westech’s hydraulics

The Westech Coyote features industrial-grade hydraulic and electrical systems which simplify use, 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 75 litres per minute at 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.
