The haulage vehicle has a frame member with separate front and rear sections that are connected to each other by universal means and are free to articulate in a plurality of planes. The frame rear section has a transversely mounted rear axle adjacent the rear portion on which a pair of propelling wheels are mounted and a transversely mounted intermediate axle adjacent the front portion of the frame rear section on which a pair of intermediate propelling wheels are mounted. The frame front section has a transversely mounted front axle on which a pair of front propelling wheels are mounted. Separate propelling motors are mounted adjacent each of the propelling wheels and are drivingly connected to the adjacent propelling wheel. All of the propelling wheels are steerable and the drive motors are movable therewith. A body member is supported on the frame rear section and a boom member is supported on the frame front section. The boom member is connected to the body member by a plurality of longitudinally extending flexible plates, so that the boom and body members are free to articulate in a plurality of planes. Endless conveying means are positioned in the longitudinal haulage compartment formed by the body and boom members. With this arrangement, all of the propelling wheels on the haulage vehicle remain in contact with the ground as the haulage vehicle moves over uneven terrain and the haulage vehicle follows the contour of the uneven terrain. |
