SOTECMA manufactures loading bellows to load bulk materials in trucks and tankers. The products generally handled are cement, dry mortar, plaster, lime, sand, industrial minerals, etc.
The operating mode is as follows. The unloader descends from its resting position towards the truck. On contact with the truck mouth, a limit switch controls the extension of the bellows to its unloading position. Another internal control limits the opening and closing of the material discharge valve.
