Abstract: A flexible feeder conveyor system for removing material from a stockpile and transporting the removed material to a fixed conveyor. The system includes an underconveyor positioned below an excavator and having a loading hopper attached to its forward end to receive material and transport it beneath the excavator a rearward end of the underconveyor. A string of trailing conveyors is towed behind the underconveyor with the last trailing conveyor having its rearward end attached to a stationary terminal support positioned at the fixed conveyor. The underconveyor, the trailing conveyors, and the terminal support are connected together using transition hoppers. Each transition hopper includes an upper hopper mounted to the raised rearward end of the forward conveyor, and a lower hopper mounted to the forward end of the next rearward conveyor. The forward end of the conveyor is rollingly supported by a pair of caster wheels.
