Ship loaders that meet ordinary to extraordinary needs
Siwertell’s market-leading ship loaders are based on screw, aeroslide or belt conveying technologies and are delivered as stand-alone equipment or as part of terminal systems. Ship loaders are supplied as stationary or rail-traveling units with telescoping and slewing configurations. For even greater access to all parts of the hold, slewing screw-type loaders can be supplied with a scissor-arm arrangement. Siwertell can deliver systems with loading capacities as high as 12,000t/h.
Siwertell ship loaders are equipped with loading chutes appropriate to the materials being loaded. Chutes are often telescopic and their length is automatically-adjusted depending on the level of material in the ship’s hold. They are specially-designed to prevent any dust emissions even when handling powdery, dusty materials.
The unloader can be operated either from the cabin or using a remote control unit directly from the side of the ship’s hold. Both arrangements offer excellent views of the loading area. The cabin is mounted on an arm at the same level as the loading boom and it slews along with the loading boom. It is fully-insulated and equipped with a heating fan and an air-conditioning unit to provide the operator with a comfortable work place, even in extreme weather conditions.
The loading conveyor can be screw, aeroslide or belt type; all are totally-enclosed to prevent any dust creation or spillage. When a belt-type conveyor is used, we can offer a telescopic loading conveyor.
The electrical system is installed in an insulated electrical housing equipped with a heating fan and an air-conditioning unit. It is made up of elements such as low voltage switchboards with a motor control center, contactors, a programmable logical control-system and the human machine interface.
A tripper is used to transfer bulk material from the shore conveyor to a traveling ship loader. The tripper travels on rails and is towed by the ship loader.
Clean and cost-effective ship loader
Siwertell ship loaders are cost effective and kind to the environment. They are supplied with loading spouts designed to suit the material to be handled, reducing dust and spillage to a minimum. These include double-walled flexible spouts and cascade-type bellows with a lightweight, compact design.
Different cargoes call for different conveyor technologies
Screw-type loaders: A screw-type ship loader is totally-enclosed and commonly used for handling powdery and dusty materials such as cement, clinker, sulphur and minerals. Screw-conveyors load ships up to Panamax size.
Aeroslide loaders: Totally-enclosed aeroslide ship loaders are generally used to handle easily-fluidized materials such as cement, dry fly ash and alumina. They can load ships up to 80,000 dwt. Aeroslide loaders must be installed on a downward slope, as gravity is essential to their operation. They can be ideal when height restrictions are a major factor.
Belt-conveyor loaders: A Siwertell belt conveyor ship loader can handle a broad range of commodities including lumpy, granular and sticky materials, such as coal, ores, minerals, grain, feedstuff and fertilizers. They benefit from low energy consumption and can load ships up to 130,000 dwt. Belt conveyors can be covered to protect cargo and minimize environmental impact and spillage.
Versatility and performance
Siwertell loaders are tailored to your needs, with a focus on performance. Outstanding performance relates not only to capacity, but also to efficiency, economy, the environment, safety and careful cargo handling.
We offer versatile systems. For example, a loader can be designed to be equally environment-friendly and efficient loading either cement or clinker; two commodities used by the same industry but with totally different characteristics. That versatility extends to vessel size; a loader can provide exactly the same effectiveness loading coastal barges or large ocean going bulk carriers.
New high capacity loader
If asked: just how much material can a Siwertell machine load directly into a ship’s holds? Using the new high capacity loader, Siwertell’s answer is: in the space of an hour, 12,000 metric tons of iron ore, or 8,000 metric tons of coal. The new loader serves some of the largest bulkers in the world; iron ore carriers of up to 300,000 dwt and 230,000 dwt coal carriers.
