ABSTRACT OF THE DISCLOSURE A transit concrete mixer is provided having a dis- placeable charging hopper which may be moved between a charging position wherein a discharge conduit thereof protects into the interior of the mixer drum and a relatively displaced position where the discharge conduit is removed from the drum to facilitate discharge of concrete from the drum. The charging hopper is pivotally attached to a support structure which also carries the rear end portion of the mixer drum and is select ively movable in a vertical plane about a horizontal axis. The relative location of the horizontal axis for pivoting move- ment of the charging hopper is located with respect to the terminal end of the hopper's discharge conduit such that the hopper and its associated conduit may be swung from one position to the other without interference with the mixer drum and its interiorally mounted blade elements. A hydraulic actuating ram is provided to facilitate the swinging movement of the charging hopper. A discharge stop plate is also provided in the combination with this plate attached to and carried by the charging hopper for concurrent displacing movement between a normal position closely adjacent the rear end of the mixer drum and a position relatively remote thereto.
