Loader device for supporting parts for heat treatment in a furnace

A loader device for supporting parts to be subjected to heat treatment in a furnace, said device being made of thermostructural composite material and comprising a plurality of trays spaced apart from one another by means of spacers,

• the device being characterized in that it comprises:
• a base;
• a loading pole secured to the base, projecting from the central portion of the base and extending over at least the full height of the loader device;
• a plurality of loading trays each provided with a central passage for passing the loading pole;
• and each loading tray carrying a plurality of spacers enabling successive trays to be assembled at predetermined intervals, each tray carrying the same number of spacers, with the spacers being aligned so that, once the trays have been assembled, the spacers make up load-carrying columns extending up the height of the loader device, and at least one of the spacers carried by each tray having a disposition and/or a size that is different from the other spacers carried by the same tray so as to enable the trays to be indexed while they are being assembled.
