Abstract: A wash station for receiving, clamping, inverting, and washing a tank and pallet assembly consists of a stationary frame having a pair of idler rollers and a pair of drive rollers, and a rotatable carriage mounted on the rollers. The carriage includes two separate vertical arcuate wheel members resting on the rollers, a transverse tank support platform extending transversely between the wheel members, transverse support struts, horizontal and vertical wheel support members, and a movable hold down clamp with an integral nozzle assembly. The hold down clamp and nozzle assembly is movable to a clamped position engaging a tank and pallet assembly resting on the support platform. When the assembly is clamped, spray nozzles are inserted within the tank. The carriage containing the tanks to be washed is then rotated 180.degree., inverting the tanks. Wash fluid is then supplied via the spray nozzles into the interior of the tanks.

Abstract: A bin for storing and transporting bulk material having a discharge opening located in one side wall and a door hingedly mounted on the side wall for movement to a closed position overlying the opening. A hinge is provided having horizontally disposed end pins on which the door is hung for up and down pivotal movement toward and away from the discharge opening. The construction of the hinge prevents the accumulation of contaminants and foreign matter around the door and enables the easy removal of the door from the bin.
