Today's stringent environmental regulations in ports require installations that are designed accordingly.
The Siwertell unloaders and loaders are some of the most environment-friendly shore based bulk handling systems available and can therefore be deployed in pollution sensitive sites or those close to populated areas.
Minimal dust creation
Cargo pick-up is carried out below the cargo surface in the ship’s holds. The Siwertell unit is designed for a layer-by-layer unloading method, which considerably minimises dust creation inside the hold from cargo avalanches.
Cargotec's Siwertell loaders and unloaders offer a conveying line based on totally enclosed screw conveyors configured in such a way as to create negative pressure in the system and avoid dust leakage at connection and transfer points.
The most common configuration of the road-mobile Siwertell system is associated with direct discharge to trucks. This is facilitated by an enclosed connection between the unloader and the receiving truck through truck loading bellows connected to a dust filter. The dust filter removes dust from the conveyed air and excess air from the loaded truck; the air is then filtered and dust particles are returned to the conveying line.
Most Siwertell road-mobile ship unloaders are self-propelled by a diesel engine. Cargotec continually upgrades the diesel engine specification to meet the latest regulations on exhaust and noise emissions.
