A launch vehicle (10) is provided for a continuous mining system including modular conveyor units (U) that may be connected together to form a conveyor train (T). The launch vehicle (10) includes an elongated frame (12) that holds a belt conveyor (14) for conveying aggregate material that is received from the conveyor train (T). A drive assembly (34) for selectively advancing and withdrawing the conveyor train is also provided on the launch vehicle. Additionally, the launch vehicle includes a mechanism (52) for adding a modular conveyor unit to the conveyor train. More specifically, the conveyor train drive assembly (34) includes a pair of cooperating tandem drive cylinders (36, 38). Each drive cylinder includes a pusher arm unit (42) 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. |
