A vacuum-type unloader for ships and barges by Belgian manufacturer Vigan. This one is a smaller version of kuid2:68213:27026:1 and with the colour toned down a little. This type of unloader is suitable for dry granular solids like coal, alumina, grain, cement, etc. An extension for the vertical suction tube is also available on the DLS (see kuid2:68213:27029:1). You can use that to adjust for the elevation of the ship being unloaded.
