Abstract:
1. A system for receiving excavated material at a mine, for comminuting the material and for transporting the material to another site, the system comprising in combination: (a) a mobile sizer having (b) a telescoping conveyor for receiving material from the discharge conveyor, the telescoping conveyor having a first end portion movably attached to the body proximate the second end portion of the discharge conveyor, and a second end portion distal from the body operatively interconnected to a mobile hopper; (c) a mobile bridge conveyor carrying the mobile hopper and operatively communicating with a conveyor system for transporting the material to a distal site; and (d) a control system operatively interconnected to the mobile sizer, the discharge conveyor, the telescoping conveyor, the mobile hopper, the bridge conveyor and the conveyor system to monitor and control functions and maintain a continuously operative interconnection therebetween for movement of the material while stationary and while moving, and for actuating the crawler track assemblies and for pivoting the pivotal crawler track assemblies in a first direction for movement through first half of a serpentine turn and for pivoting the pivotal crawler track assemblies in a second direction for movement through second half of a serpentine turn to advance the mobile sizer in a direction perpendicular to the elongate length of the body.
