The conveyors have been designed for hanging the parts to be treated in the vertical direction.
They allow only to one person to perform all the working steps of a product (load-unload, impregnation, painting and stacking-drying). Indeed, once the parts have hung, the handling is performed automatically. The conveyors are provided with part-carrying bars, the size of which is in accordance with the user’s needs, and which are provided with double trucks each one provided with 8 bearings, sliding into metallic double rails; a third rail contains the chain hooking the bars while handling them.
The bar handling is obtained with powered translations and pneumatic thrust units having adequate power. These two-rail plants are well more sturdy and reliable than the single rail conveyors, in that they allow the materials to be treated to be hung at random and not to be arranged centrally with respect to the bar middle.
