Services
High Angle Conveyors
DSI's Sandwich Belt High Angle Conveyors move bulk materials at inclines up to 90 using dual belts. This technology eliminates limitations of traditional systems, offering low maintenance and high throughput for industries like mining and port operations. Systems handle capacities exceeding 10,000 t/h with reliability in challenging environments.
Shiploading Solutions
Mobile shiploaders with DSI's conveyor technology enable efficient loading of ships with minimal dock space. These systems handle materials like ore, grain, and woodchips at high capacities, featuring remote-controlled mobility for flexible operations in ports and terminals.
Engineering Consulting
We provide feasibility studies, structural analysis, and system optimization using proprietary ExConTec software. Services include conveyor design, failure analysis, and field support for upgrades, ensuring operational efficiency and compliance with industry standards across global projects.
Overland Conveyors
Custom-engineered overland conveyors transport materials across complex terrains with high capacity and minimal environmental impact. Systems integrate advanced take-up technologies and booster drives to handle long distances and elevation changes efficiently.
Field Advisory Services
Expert technicians provide installation guidance, system audits, and maintenance training to optimize conveyor performance. This includes belt alignment, tensioning, and troubleshooting to minimize downtime and extend equipment lifespan for continuous operations.
