Claim:
A portable hoist attachable to and for use in combination with a hand truck comprising: (a) an adapter assembly comprising: a rigid u-shaped embodiment formed by two flat plates bridged to one another, substantially parallel with respect to one another and sufficiently spaced apart from one another so as to allow said u-shaped embodiment to sandwich a nose plate of said hand truck; a segment of angle iron attached to an outer surface of one of said two flat plates and positioned parallel with respect to the bridge of said u-shaped embodiment, rendering one leg of said segment of angle iron perpendicular to said outer surface and; at least one c-shaped leg receiver attached to said one leg of said segment of angle iron; (b) at least one leg for load support made of elongated tubing and having adequate outside dimensional properties so as to allow for insertion of said at least one leg into an open end of said at least one c-shaped leg receiver, one end of said at least one leg having a flat plate attached so as to permit the attachment of a caster to increase mobility of said portable hoist when in use; (c) a mast made of elongated tubing attached at one end to an outer surface of said u-shaped embodiment opposite said at least one c-shaped leg receiver; (d) a jib assembly attachable to said mast comprising: a jib mounting bracket made of c-shaped channel, the inside dimensions of which conforming to the width and at least partial depth dimensions of said mast; a boom made of elongated tubing attached at one end to an outer surface of said jib mounting bracket and substantially perpendicular with respect to said jib mounting bracket and; a boom support made of elongated tubing attached to said jib mounting bracket at one end and attached to said boom at the opposing end; (e) a rotatable sheave attached to said boom so as to allow a cable to be utilized via said jib assembly and; (f) an arm made of elongated tubing, attachable at one end to said mast and attachable at an opposing end to a handle of said hand truck, forming a contiguous brace to maintain the proximities of both said mast and said hand truck with respect to one another when said hoist is in the upright operational position and providing a surface upon which to attach a winch in such a fashion as to physically permit the operator of said hoist to grasp said handle of said hand truck with one hand while operating said winch with the other hand.
