At the beginning of the loading process, the bellows are lowered into the loading area of the truck/ship or the area and remain on the ground. The material falls freely through the bellows. A flexible dust skirt on the underside of the bellows keeps the dust within the loading area. The additional vacuum air of the dust extraction system ensures effective prevention of dust emissions. Level sensors connected to the device continuously monitor the product level. The bellows are automatically lifted when the filling level rises. At the end of the loading process, the loading bellows return to the upper resting position. Open truck loading bellows, ship loading bellows and storage loading bellows are available in various models and configurations depending on the type of bulk material, loading capacity and application requirements.
