Long distance belt conveyor

The long-distance belt conveyor is an intelligent conveying system developed for complex terrains and extended transportation needs, employing modular design principles with single-unit conveying distances up to 20 kilometers and minimum horizontal turning radius of 300 meters. This integrated system combines terrain adaptation technology, dynamic tension compensation systems, and intelligent monitoring modules, replacing traditional multi-stage relay conveying solutions to achieve continuous all-terrain transportation of bulk materials including ores, coal, and aggregates.
