The Rival Hydrovac unit has the ability to pressure off loads, as opposed to the conventional dumping of each load. This allows for a more rapid and, when required, controlled off-loading of slurried loads. A hose can be connected to the rear valve, and the load can be forced into another container, truck, trailer, or wherever it needs to be moved. As off-loading becomes more of a challenge, the unit allows for a more versatile approach to getting the debris to a secondary location or vehicle in a controlled manner quickly. The process is accomplished by moving a lever, closing the boom valve and opening a valve on the rear of the truck. The truck can be hoisted while the pressure-off process is occurring, allowing for a more complete dump cycle. It allows the unit to remain on site and pressure each load to a waiting tank or vehicle. 844-467-4825; www.rivalhydrovac.com
