ABSTRACT:
An elevated roadway for use with a self-propelled continuous haulage unit in underground mining consists of a multiplicity of substantially identical roadway units joined together end to end. Each unit has a pair of elongated bottom side beams joined by bottom cross beams, columns arranged in laterally opposite pairs and supported on the side beams and a pair of elongated track members supported on the upper ends of the columns and defining a track for trams to move over the roadway above the haulage unit. Longitudinal brace beams and transverse brace beams join the columns. The durability and rigidity of the unit is enhanced by diagonal brace beams connecting selected ones of the columns and by gussets at each joint between the bottom side beams and the bottom transverse beams.
