AllExcavate hydroexcavators from Vacall – Gradall Industries have a step-in compartment to provide operators with warmth and protection from inclement weather. The heated compartment is roomy with enough space for an operator to change out of wet and muddy clothing. It has floor drainage, racks to hang dry clothing, heated cabinets for the hose reel and water pumps, and boilers that can heat water for more effective hydroexcavation in frozen ground. The unit uses high-pressure jetting action to loosen soil, rocks and clay, and then vacuum forces up to 27 inches Hg and 5,800 cfm to remove the material and water slurry into a debris tank. 800/382-8302; www.vacall.com
