ABSTRACT:
This tongslike device for automatically loading and unloading materials, such as dirt or soil, sand, gravel, vegetables, fruit and leaves and even containerized loads, comprises two elongated members, pivoted approximately midway with a pivot pin. The lower portions of the device are flared to enable it to hold more material or larger size containerized loads. Its weight distribution between its upper and lower portions is such that its lower portions will separate automatically at touch down. The ends of its lower portions or jaws may be serrated and sharpened to enable it to dig into the ground or other material for loading. In one version, the device is capable of scooping up a load cable automatically because of the shape of its jaws. The size and shape of its lower portions determine the material or size and shape of the load capable of being scooped up. Such automatic loading and unloading devices would make the cargo loading and unloading operations safer and speedier under hazardous environmental conditions.
