Abstract: A machine structure, in particular for the processing of fluid products, including a loadbearing frame with vertical uprights (12) connected by two horizontal plates (14, 15) at a distance from each other. Between the uprights are located one or more removable covering panels (13) which cover the zone housing the machine components. The machine structure is strong but light, not very bulky and easy to assemble even by non-specialist personnel.

Abstract: An apparatus for processing fluid products, in particular paints and the like, comprising a main structure (11) which defines a housing space (15) having an access opening (16), door means (17) which are coupled to the main structure (11) and which can be selectively moved from a closed position to an open position of at least part of the access opening (16), and vice versa, and support means (20, 22, 50) for at least one container of fluid products to be processed, which support means are housed in the main structure (11) and can be moved from an operating processing position to a position for loading/unloading the at least one container. The door means (17) comprise movement means (22, 17, 74) which mechanically interact with the support means (22, 50) in order to move them from the operating processing position to the loading/unloading position as a result of selective opening of the door means.
