EF-80R Tracked Radial Feeder Stacker

The ERF-80R feeder stacker features a large feeder hopper that transfers material onto an 80ft conveyor, all fitted to a slew ring assembly allowing for full 360° radial. Designed to allow operators to stockpile/transfer material, it eliminates double handling of materials. Its maneuverability makes this unit very versatile and makes it ideal for barge loading and unloading, rail loading / unloading and stockpiling, the ability to move parallel enables the operator to maneuver the unit parallel to the vessel meaning the machine can crab alongside.

The unit can also be compacted for transport on one low loader for easy site to site transport.
