  • Hauling tarpaulin for single-handed operation
    Patent number: 6565101
    Abstract: This hauling tarpaulin can be deployed, loaded with refuse, moved and unloaded by a single person. A stored tarpaulin rolled about a mandrel is easily unrolled and filled with lawn refuse. The mandrel holds the tarpaulin flat on the ground despite wind. When the hauling tarpaulin is filled with refuse, the hauling line is pulled, causing the mandrel to rise up on its legs, and the sides to rise, forming a boat-shaped structure which engulfs the refuse. The hauling tarpaulin then is pulled by the hauling line to the refuse collecting point. At the collecting point the tarpaulin is restored to its flat form and the waste material unloaded.
