The DV12KVL Dump Box Vibrator from Del Hydraulics vibrates sticky loads and moves material out quickly and cleanly. The self-contained unit is built on a steel frame, ready for quick mounting underneath a dump box. There is no need for an external power source, as the unit runs off the truck’s 12-volt battery. The direct-drive system reduces driveline and box damage, and will loosen sticky, wet and frozen materials. It is recommended for tandem- and tri-axle vehicles. 716/853-7996; www.delhydraulics.com.
