Homeowners, shopkeepers and small manufacturing operations all have a need occasionally to lift a box or piece of equipment into the bed of a pickup or the back of a station wagon that is too heavy to be lifted by hand. Of course, trucks equipped with hydraulically-operated lift gates accomplish this purpose quite satisfactorily but small businesses and individuals can seldom justify the expense of such a truck when the need therefor is sporadic. Also, these units require that the load be transferred from the gate to the bed and back again to be unloaded. Most hoists, for that matter, do not remain with the load-transporting vehicle and, therefore, some transfer of the load from the hoist must, of necessity, take place.
