ABSTRACT:
A launch vehicle (10) is provided for a continuous mining system including modular conveyor units (U) that are connected together to form a conveyor train. The launch vehicle (10) includes a main frame (12) for supporting a rearmost conveyor unit (U) of the conveyor train. The main frame (12) includes a first side over which additional conveyor units (U) are added to the conveyor train and a second side. A belly conveyor (14) is carried on the main frame (12). A drive assembly (42) is provided for selectively advancing and withdrawing the conveyor train. Further the launch vehicle (10) includes a canopy (18) overlying the main frame (12). The canopy (18) is mounted on at least one cantilever support (20) extending upwardly adjacent the second side of the main frame (12) whereby the first side is left open for adding additional conveyor units (U) to the conveyor train.
