    • Features
    • Specifications


    Scraper Driveline Guard

    Scraper driveline guard protects the output case, differential and ejector cylinder to help minimize driveline maintenance costs.

    Optional Retarder

    The optional retarder extends brake life when working on severe, downhill slopes.


    Rounded off bumpers reduce hooking into high walls.


    Extensive use of castings in the frame, hitch and bowl provide long service life.

    Wiring Harness and Hose Assemblies

    Wiring harness and hose assemblies run down the draft arms to eliminate the need for "jump-over" line which can reduce hydraulic system efficiency.


    Standard tires provide the maximum flotation of the available options.

    Laminated Thermo-Shield

    Laminated Thermo-Shield helps keep surface temperatures in the engine compartment below the flash point of diesel fuel.

    Coal Bowl Scraper Benefits

    Dual Engines

    Dual Engines allow Coal Bowl Scrapers to achieve maximum payloads and deliver fast cycle times.


    All-Wheel-Drive allows the machine to work effectively in poor underfoot conditions and climb piles of slippery, loose coal.

    Large Capacity Coal Bowls

    Coal Bowls are longer and higher than standard scraper bowls, which allows you to haul 50 cubic yards (38 cubic meters) with a 637G.

    Compaction Capability

    Coal bowl scrapers are effective in compacting coal, which reduces the risk of spontaneous combustion of coal in the stockpile by eliminating the air spaces.

    Coal Stockpile Management

    Maintaining the Coal Stockpile

    Coal Bowl Scrapers are effective in compacting coal, which reduces the possibility of spontaneous combustion in the coal stockpile. This allows your company to meet plant safety regulations and eliminates the need for additional compaction equipment.

    Reclaiming Coal from the Stockpile

    When incoming coal shipments cannot satisfy your coal burn requirements, you need a way to reclaim the coal off the stockpile. Coal Bowl Scrapers can move coal from the stockpile to the inlet supply of the plant.

    Building the Coal Stockpile

    Coal Bowl Scrapers allow you to create your coal stockpile by self-loading coal in the receiving area, hauling it to the stockpile area, and dumping coal in thin lifts.
