ABSTRACT:
An improved cross-pit conveyor is provided for transferring excavated topsoils from the working side across the pit to the reclamation side in a strip mining operation. The machine includes a base to be positioned on the working side, a slewable upper frame mounted on the base, a long cantilevered conveyor pivotably supported at one end by the upper frame and reaching across the pit, and a separate on-board auxiliary conveyor for initially receiving the excavated material and feeding it smoothly onto the cantilevered conveyor. The receiving end of the auxiliary conveyor is pivotably connected to the back of the upper frame, and the discharging end is floatingly supported on the receiving end of the main conveyor to maintain a constant cooperative association therewith regardless of the hoist angle of the main conveyor.
