Abstract: A system for the alternative charging of at least one sack filling machine and/or of at least one truck with pourable material, which is stored in a plurality of silos, which are firmly braced by columns, whereby each of the truck and the sack filling machine can be moved under desired silo outlets, and whereby, following the filling of the sacks, the sacks can be transported from the filling system over a totally or partially traversible intermediate conveyor to one of several conveyor belts. The intermediate conveyor, assigned to at least one filling machine, is designed as a traversible elevator at least over some regions. When in the working position, the discharge end of the conveyor corresponds with one of the conveyor belts, arranged above the required passage height necessary to move the sack filling machine or the truck.
