ABSTRACT:
A mine haulage vehicle comprising a body having front and rear sections which are pivotally interconnected at adjacent ends enabling them to swing freely in a horizontal plane relative to each other about a vertical pivot axis. The body has a pair of ground-engaging wheels on each of the body sections. The vehicle is steered by hydraulic cylinders connected between the body sections for swinging them about the pivot axis. The body sections have aligned trough-shaped compartments extending substantially its full length and containing a horizontally flexible, center strand, orbital, chain conveyor. The rear body section has a load-carrying compartment above the conveyor and has upstanding push blades on opposite sides of the conveyor with power cylinders to move the blades inwardly and to transfer material onto the conveyor during unloading. Use of the vehicle is characterized by one-direction movement of load by the conveyor so it is never necessary to turn the vehicle around while transferring material from a mine face to a remote discharge location, and movement around tight corners is facilitated by the relative horizontal swinging movement between the two body sections.
