Rail Wagon Discharge

For financial and ecological reasons, silo rail wagons are increasingly used for transporting bulk products. The regional distribution of these bulk products is ensured by appropriate silo trucks. The transhipment systems constitute the link for transhipment of materials from rail to road. We are your specialist regarding the conception and realisation of your rail wagon discharge system, irrespective of the particular bulk material. STAG has realised a wide variety of systems, ranging from a manual single discharge system to an automatic block shipment of rail wagons.

Technical Specifications
Application/ Functional

Depending on the respective requirements, two material connections and one conveying air connection are installed for each rail wagon in order to ensure the rail wagon unloading. The number of rail wagon connections may be selected at will and is depending on the local condi-tions. The rail wagon unloading into the target silos takes place using the dense phase method. The necessary conveying air is provided by a compressor unit. All electronic components, such as silo filling level, silo selection, etc. are monitored and operated via a control cabinet.
