Abstract: A hauling system and hauling car for hauling mined materials includes a body defining a storage area for receiving the mined materials, a conveyor positioned in a bottom portion of the storage area, and a motor coupled with the conveyor and driving the conveyor. The motor is controllably operable via a remote control system, and the body includes at least one connector connectable to a winch system that controllably advances and retrieves the hauling car. The use of a winch system for advancing and retrieving the hauling car provides for increased volumetric capacity. Additionally, the structure enables transport of evenly distributed loads and more efficient dumping.
