摘要： At least one hollow rotatable drum is movable between a first and a second position in the latter of which it can receive and discharge its contents. First displacing means is provided for displacing the drum between its positions. Container means is movable between an upper and a lower position in which it is respectively located above and below the level of the drum when the latter is in the second position thereof. A hoist or similar means displaces the container means between the upper and lower positions thereof. Connecting means connects the interiors of the drum and the container means and enables gravity discharge of the contents of the drum to the container means when the drum is in the second position and the container means is in the lower position, and of the contents of the container means to the drum when the former is in the upper is in its upper position and the drum is in its second position.

摘要： A frame is provided with at least two axially parallel cylindrical rollers on which a drum can be supported on its axially spaced wheels. The drum has axially projecting central pins, and a servicing arrangement is adjacent the frame so that the drum may be moved into the servicing arrangement and back to the frame, for servicing and operating purposes. The servicing arrangement has a guide surface extending from the region of the cylindrical rollers outwardly of the frame and having a free edge remote from the rollers. Two or more support elements are provided having edge faces provided with notches into which the axially projecting pins of the drum can engage when the drum rolls on its wheels over the guide surface and off the free edge.
