Hook lift silos

Hook lift silos, also called Norman Bock silos or exchange silos, are using a central hook on the top and on the side at the changeover to the cylinder. This system allows placing or lifting the silos vertically as well as horizontally. Furthermore, most of the silos do have pins on the vertical supporter that allows lifting up the silos with a semi-trailer. A further receiver system is the so called BTE or AKA-system in connection with a Delta-pro lifting system.

Hook lift silos are used widely in the dry mortar industry, for material like gypsum, masonry mortar, screed, self-leveling floor screed and geothermal drilling. But also as stationary silos for granulates, and in the industrial farming for feeding stuff and fertilizer.
