ABSTRACT:
A portable frame having ground engageable wheels and a scale has an elongated linkage consisting of two pivotally actuated pairs of beams with reinforced cross members. A pivoted, hydraulic first motor is engageable with a hopper adapted to receive the dry mix ingredients. When the hydraulic motor is actuated, extendable movement of the piston causes the hopper to be swung upwardly and the hopper is simultaneously tilted to a vertical position. At maximum extension of the hydraulic motor, a pivoted hydraulic second motor acting at one end through one of the linkages and through the hopper at the other, effects further tilting movement of the hopper, to a substantially vertical position. The ingredients are then discharged through a chute section of the hopper into a self-transit concrete mixer truck.
