Gagarin Factory, Russia

Silos for the Gagarin Factory in Russia

This silo work for the Gagarin Factory in western Russia was completed in late 2015. The winter conditions were not a problem for the slipforming operation as the slipform platform is very compact and can be readily heated and shielded from the elements. Note the openings and block-outs in the walls, which are easily created by inserting custom wood frames into the slipform setup as it climbs upwards. The tallest silo has a height of 26.5 m.

A specialist subcontractor was hired by Egger Holzwerkstoffe Brilon GmbH & Co KG for slipforming the silo shells.
