The Wheelwash Division of Global Equipment has designed the Rhino Wheelwash to help fleets avoid fines for contaminated tires. The self-contained, go-anywhere system is modular and arrives in two pieces, which are then bolted together. It can be assembled onsite in about two hours. No excavation is necessary—only a concrete/asphalt pad or crushed-stone base. The settlement tank/weir system recycles 90 percent of the water. Wash time lasts from 15 to 45 seconds and can be regulated up to 3 minutes by changing the settings at the control panel.
