A concrete mixer has a drum formed in two axially separable parts 1, 2 of which the lower part 1 is rotatable by a motor 12 through a reduction gear 14. There is a stirrer 3 which is rotatable relatively to the lower part 1 of the mixing container but not relatively to the upper part 2. The whole is carried on an arm 9 and is pivotable about the horizontal shaft 10 into an elevated position. In the filling and mixing position shown in full lines, the two parts of the container are separated to present an annular filling aperture and the upper part 2 and stirrer 3 are held stationary while the lower part 1 rotates. The container is then closed to the position 2b and raised to . the elevated position ; in the closed position the upper part and the stirrer are clutched by dogs to the lower part (see Fig. 4, not shown), so that they rotate as a unit and mixing proceeds in the elevated position by tumbler action. Finally the mixer is discharged by moving the upper part to the position 2a, providing a discharging aperture formed by a wider separation of the container components than for filling. The motor 12 may also drive a hydraulic pump for actuating hydraulic means to open and close the container and elevate it. There are transport wheels (see Figs. 2 and 3, not shown) which are retractable into the body by means of an hydraulic ram. There may be a weighing device 15.
