Benefits & Features

Coal Bowl Scraper Benefits

Dependable Coal Management and Hauling

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

Coal Bowl Scrapers are the ideal stockpile management tool.

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.
