Abstract: A conveying system for heavy material such as overburden that contains large rocks as well as small rocks and dirt. The system has a feed system using two blades that rotate over an apron to push material onto the conveyor and a transition assembly between conveyors that lessens the impact of large rock as it drops from one conveyor onto the next conveyor.

Abstract: A heavy duty structure that forms a mobile loading system is shown that is comprised of a ramp means, a dump means and crawler undercarriage for use in loading trucks by making use of bulldozers. The crawler undercarriage supports the carrier or platform which provides the base for the superstructure, power units and hydraulic systems. The system's power unit supplies the source of power to move the crawlers so the structure may be moved to any locality on the job-site. The system's power unit also supplies power to the hydraulic systems provided to raise and lower the ramp and dump means. The carrier supports a mast means which supports the ramp means and dump means. The ramp means provides a bridge or lifting means onto which a pair of bulldozers may be alternatively driven to move the overburden to the dump means.
