ABSTRACT:
A mechanical shovel comprises a digging tool, two booms and a harness. One of the booms is adapted to be mounted by the harness on and substantially parallel to the back of an operator so that the other boom extends forwardly of the operator. One of the booms supports a winding mechanism having a cable leading along the forwardly extending boom and attached to the handle of the digging tool. The handle of the digging tool is provided with means to activate the winding mechanism so that the shovel may be raised with the minimum of effort on the part of the operator. The combination of the two booms provides a particularly stable arrangement.
