Chain Conveyors are based on the movement of an endless chain, that is driven in a rectangular trough by an interlocked transmission chain. With the stag technology, apart from horizontal Conveyors which can be as long as 40 meters, Chain Conveyors are also used as Slope Conveyors and Vertical Conveyors with slope angles from 25 to 90 degrees and with possible conveyance heights up to 30 m. The robust equipment is applied for discharging, loading, or separating units.
