4.7 Double Chain Conveyor
The chain conveyor is arranged in the centre of the machine. It transports the material picked up by the
two loader stars to the rear end of the machine, using a double chain conveying system.
The chain is a standard round link chain, size 19 x 64.5 [mm].
The chain conveyor is driven by a hydraulic motor via a bevel-planetary gearbox.
The surface of the chain conveyor which is in contact with the transported material is protected with
special 12 [mm] thick high wear resistant plates.
The discharge end of the double chain conveyor is high enough above track level and allows easy loading
of most of the common truck types.
The maximum conveying capacity is 350 [m³/h] ensures a fast loading of the truck.
The large conveyor throat opening of 800 [mm] x 490 [mm] allows the passage of large lumps.
