ABSTRACT:
A launch vehicle is provided for a continuous mining system including modular conveyor units that may be connected together to form a conveyor train. The launch vehicle includes an elongated frame that holds a belt conveyor for conveying aggregate material that is received from the conveyor train. A drive assembly for selectively advancing and withdrawing the conveyor train is also provided on the launch vehicle. Additionally, the launch vehicle includes a mechanism for adding a modular conveyor unit to the conveyor train. More specifically, the conveyor train drive assembly includes a pair of cooperating tandem drive cylinders. Each drive cylinder includes a pusher arm unit that is adapted to engage one of the modular conveyor units of the conveyor train. The conveyor unit adding mechanism includes a positioning mechanism that holds and places a conveyor unit on the launch vehicle. A pusher cylinder is also provided to push the new conveyor unit into engagement with the rear of the conveyor train. The launch vehicle also includes an extensible front end.
