These Portable Dirt Conveyors are lightweight and compact. They fit into basement windows and cellars and are ideal for excavating dirt and rubble. Shown with the dolly, these Portable Dirt Conveyors can move loose materials like dirt, gravel, and debris at up to a 45 degree incline efficiently. Note that the dolly is typically removed with a few quick latches before using the conveyor. Then it will fit through many windows, down into basements and crawl spaces. The rubber belt has plastic paddles to move the dirt upward.
