Abstract: A tube conveyor with a device for protecting the conveyor belt of the tube conveyor against volumetric overloading, the tube conveyor containing a middle part, situated between a filling site and a discharge site. The conveyor belt coiled essentially into the shape of a tube by the action of rollers mounted on roller stands, a measuring stand is arranged behind the filling site, the measuring stand comprising a stationary frame and a swiveling frame able to pivot relative to the stationary frame, the stationary frame comprising lower rollers mounted beneath a horizontal transverse axis of the coiled conveyor belt, the swiveling frame having upper inclined rollers mounted above the horizontal transverse axis of the coiled conveyor belt and having a force measuring device provided for continuous detection of the loading forces transferred from the conveyor belt, and provided for sending signals representing the loading forces to a control unit.
