Abstract
Abstract The present invention comprises a mounting means for a concrete mixer drum having one end adapted to be mounted rotatably to a truck. A power shaft is fixed to the drum for rotating it and the power shaft is rotatably mounted within a power shaft housing. The mounting means comprises a collar surrounding and gripping the power shaft housing, the collar having an upper mounting member and a lower mounting member thereon. The upper mounting member is rotatably mounted to a support means for rotation about an upstanding axis, and the lower mounting member is mounted in a ball and socket joint to the support means so as to carry the weight of the concrete mixer. The support means is fixed to the truck frame so that the ball and socket joint transfers the weight of the mixing drum to the truck frame.
