Cleaning system and methods for a mixing truck
First Claim
1. A cleaning and recycling system for a mixing truck having a mixing drum for mixing cementitious materials and a loading hopper, the system comprising:
- a delivery chute adapted for attachment to the mixing truck, the delivery chute being adapted to receive cementitious material from the mixing drum for transport to a delivery site;
a rail, having a top end and a bottom end, the rail being adapted for attachment to the mixing truck so that the bottom end is near a ground surface and the top end is near the loading hopper;
a canister that is movable between the delivery chute and the rail so that cementitious material remaining in the delivery chute may be washed into the canister;
a lifting mechanism movably attached to the rail, the lifting mechanism including a securing device so that the lifting mechanism may secure and transport the canister along the rail to allow material washed into the canister from the delivery chute to be transferred back into the mixing drum through the loading hopper.

Abstract
The invention provides systems, methods and apparatus for cleaning a mixing truck by removing and recycling any non-delivered material. In one exemplary system, the invention is preferably attached to a mixing truck having at least one delivery chute and a loading hopper. A rail is configured to be attached to the mixing truck so that the bottom end is near a ground surface and the top end is near the loading hopper. The system further comprises a canister that is movable between the delivery chute and the rail. A lifting mechanism is movably attached to the rail and includes a securing device so that the lifting mechanism may secure and transport the canister along the rail. In this manner, material remaining in the delivery chute may be washed into the canister when positioned below the chute. The canister may then be moved near the rail and secured to the lifting mechanism which in turn transports the canister to the loading hopper where the contents may be emptied.
