A gear motor driven screw conveyor running in the filling tray transports the chips horizontally into the rising screw conveyor. The filling trough is designed very low and therefore optimally suitable for all common tippers and push-off carts. The touch-down wall can also be repositioned, so the filling trough can be fed from both sides. The rising screw conveyor - driven by a gear motor - conveys the wood chips from below directly into the bunker or into a horizontal screw conveyor.
