ABSTRACT:
A self-propelled mining vehicle is disclosed which is self supporting above the floor of a mine tunnel. The vehicle is adapted to be supported above the floor of the mine tunnel such that conventional rock removing vehicles are operable therebeneath. The vehicle has an elongated carrier or frame having a mining apparatus mounted at one end. Four transverse bracing cap assemblies are included, and are adapted to engage side walls of a mine tunnel for supporting the carrier above the tunnel floor. Four suspension links extend downwardly from each cap assembly for suspending the carrier beneath the cap assemblies. The suspension links are longitudinally movable with respect to the carrier and cap assemblies for causing movement of the carrier and cap assemblies relative to one another. With such a construction, the vehicle is able to hold its position above a mine tunnel floor without contacting the floor. The vehicle is also able to walk along mine tunnel walls to travel fore and aft, and up and down, within a mine tunnel. Additionally, the vehicle is able to change its heading for travelling along a curved mine tunnel or vein.
