Hydrovacs from Camex are ideal for daylighting, trenching, pole and pylon holes, and service repair pits. Because the Hibon pump is reversible, they can be used for water and debris removal and tank clean-out. Remote control on the 6- or 8-inch-diameter booms provides one-man manipulation and operation. The boom has a 30-foot reach. The unit can dig effectively in all soil types, including clay, and with the aid of an onboard boiler, it provides a safe means of digging in frozen ground, enabling work to be done in areas of limited access and extreme conditions. 780/955-2770; www.camex.com.
