Spreaders by thyssenkrupp

Spreaders form the last member of a continuous transport material system and are used to efficiently dump or spread overburden and waste material at the landfill area which they receive from the upstream shiftable dump conveyor using a tripper car or a mobile transfer conveyor.

Being able to dump the overburden material in a controlled and efficient way, the spreader significantly contributes to the recultivation of a mined out minefield and to the reduction of the mine’s environmental impact

Your added value

• Highest efficiency in handling large amounts of overburden
• Maximized flexibility in dumping activities at a mine’s landfill area
• Tailor-made solutions for any application and customer-demands
• Sophisticated machine control concepts for operation assistance
• Improved environmental impact of the mine by controlled recultivation

Spreader Operations

Spreaders are able to dump the overburden and waste material in low-dump operation under or directly onto the current driving level. The freshly filled soil forms the new driving level during the further advance of the landfill area. Spreaders with a liftable discharge conveyor can also operate in high-dump operations to backfill the soil above the current driving plateau.

Depending on the application- and customer-specific use case, high-dump and low-dump operation can be combined for enhanced capacity with less effort in relocation of the shiftable dump conveyors.

Design Features of thyssenkrupp Spreaders

With the focus on application- and customer-specific use cases, spreaders can be realized with a single conveyor boom, as a spreader with two conveyors and low-mounted counterweight boom or as a conventional machine with receiving bridge and discharge boom conveyors with top-mounted counterweight boom.

Crawler–based travel mechanisms below the center enable an enhanced flexibility in operation and a minimization of relocation-downtimes. A slewable central superstructure connects the conveyor booms and provides the operator’s cab in a position with an optimal view over the equipment. The discharge conveyor boom is designed as a liftable structure to achieve a controlled dumping process during high-dump and low-dump operations. The bridge conveyor transports the material from the upstream equipment and can be designed with or without a support car below the bridge structure. A counterweight boom contains the electrical equipment of the machine and further smaller equipment-units.

Our Spreader Portfolio

thyssenkrupp offers a complete range of spreaders as custom-made solutions for the specific applications and are optimized for the requirements of each use-case.

Starting with small units of compact design and a single conveyor boom, up to large spreaders with multiple conveyors and discharge boom lengths of over 100 m and capacities of 22.500 m³/h, a wide spectrum of solutions is available for any customer requirements. A particularly remarkable solution is the cross-pit spreader on crawlers, which, with a boom length of 207 m, enables tipping even over long distances.

Tripper Cars by thyssenkrupp

Tripper cars are used for the material discharge from the belt conveyors at the landfill area in continuous material transport systems of IPCC applications. In order to be able to work on the entire length of the conveyor line, they are equipped with either a rail or crawler undercarriage as a mobile discharge point from the conveyor. Depending on the desired degree of system flexibility, tripper cars are equipped either with or without an own rotating and lifting discharge conveyor. 

In case that a downstream spreader is to further transport the material, the tripper car forms the mandatory connecting link between the conveyor line and the spreader. For this, the receiving conveyor of the spreader is either supported on a trailer of the tripper car or is equipped with a separate support car. For smaller applications, a standalone tripper car with an own discharge boom operates without a downstream spreader. 

Advantages of Tripper Cars by thyssenkrupp  

• Efficient discharge of overburden and waste material over the entire length of the conveyor 
• Steady and regular distribution of bulk material (allows for the reliable execution of your stacking plan) 
• Maximized flexibility in dumping activities at a mine’s landfill area  

• No more need for small excavators or trucks – which means lower operational cost and a more controlled and safe working environment 
• Improved environmental impact of the mine by controlled recultivation 

Tripper Car operations:

Tripper Cars can be used in a wide array of different discharge systems. They can directly dump bulk material or redirect the material onto a spreader for increased flexibility. The Tripper Car can move forward and backwards along the entire length of the conveyor system, as they are either equipped with a rail or crawler undercarriage. Through the mobility of the Tripper Cars, the unloading point of the conveyor system becomes flexible and allows for an automated and reliable dumping process of the bulk material.
