The largest silo facility for winter services was realised in the middle of the city of Bern. Three wooden silos with a storage volume of 900 m3 each were built directly next to the Wankdorf stadium. The filling with salt is carried out by means of a hopper conveyor system, which achieves a conveying capacity of up to 50 t/h. This enables delivery with simple dump trucks. The removal of the salt from the silo into the gritting vehicles is fully automatic from the vehicle cabin.The entire system is managed and monitored via internet.
