ABSTRACT OF THE INVENTION A portable hoist is provided for lifting, transporting, and depositing loads onto a platform, such as a work bench, or into a vehicle, such as a pick-up truck. The portable hoist comprises a mounting for attachment to the supporting means, an upright support structure connected to the mounting by a means which allows for swinging movement of the support structure about its vertical axis, and a boom pivotally secured at one end to the upper end of the support structure such that the free end of the boom can be raised and lowered. A means acting between the support structure and the boom serves to raise and lower the boom. A sheave is carried at the free end of the boom and a hoist line connected to the support structure at a level substan- tially below the pivotal connection of the structure to the boom loops over the sheave and carries means for attachment to the load to be lifted.
