The Siwertell inlet feeder for a vertical screw was invented in 1974, and patented and tested by two Swedish inventors, Olle Siwersson and Gunnar Tell. The potential for using the screw for a ship unloader application was recognised at an early stage, and the first screw-type ship unloader was born.

The two inventors decided to combine their surnames to create the brand - Siwertell. Our company name and owner have changed a number of times, but Siwertell remains a world leading brand within the dry bulk handling market.
