Ship unloader - Germany

Siwertell Ship unloader for coal, Germany

Environment-friendly unloading in city centre

Siwertell was awarded the supply of a unique coal handling system, in order to renew an old port area and create a modern office and residential area near a coal terminal in Frankfurt am Main, Germany.


This order was placed to enable the renewal of an old port area into a modern office and residential area, while maintaining the supply of coal to the existing Mainova power plant. 

With its well proven and environment- friendly design, Siwertell was able to fulfil the extremely high environmental demands in this exclusive residential and office area. Special attention was given to the architectural aspects in this project because of the surrounding buildings. 

Besides the new unloader, the equipment supply included a belt conveyor and supporting steel structures with the required noise and dust enclosures. A belt scale and a magnetic separator were also part of the delivery. The scope of supply further included freight, mechanical and electrical erection as well as commissioning and start-up.

The Siwertell continuous, screw-type unloader discharges coal onto a belt conveyor running through a new office building, over a public road and a railway, into the Mainova power plant. 

An clean, sustainable and continuous unloading operation is ensured through the totally enclosed conveying system.
