Abstract:

An onboard washing system provides the ability to wash specific areas at the rear of a concrete truck, without requiring an operator to climb a ladder or climb on the truck. Certain specified areas which are traditionally difficult to wash, including the inside of the charge hopper, the interior portions of the discharge chute, and rear portions of the mixing drum structure, can now be washed in an automated and efficient manner. The truck-mounted washing system has components which are specifically positioned to cause washing fluid (water) to be sprayed or directed toward predetermined areas in an efficient and effective manner. The system also includes hand-held washing wands or washing mechanisms, which allow an operator to easily reach additional zones or additional areas at the rear of the truck, which are lower. Most significantly, the truck-mounted wash systems and the hand-held nozzle systems (wand) are all operable while an operator remains on the ground.
