Abstract
An articulated shuttlecar having two end sections and at least one center section with spaced longitudinal edges. A vertical pivot connecting the center section to one end of each end section. Each section has a pair of driven wheels mounted on an axis located approximately at its longitudinal center. A continuous flexible conveyor extends throughout the length of the sections of the shuttlecar to transport loose mined material from one end of the shuttlecar to the other end of the shuttlecar, and a continuous flexible retaining wall extends upwardly along each edge of all of the sections of the elongated shuttlecar to maintain loose mined material on the continuous flexible conveyor.
