A portable lifting apparatus is provided. The apparatus has a modular frame comprising a first frame member and a second frame member, which in combination support a load-bearing beam having a lifting device secured thereto above a lifting surface. The first frame member, the second frame member, and the lifting device are each removably secured to the beam such that the apparatus may be disassembled into constituent components for transport or storage. Each frame member may be configured to disassemble into constituent components comprising a base and two or more support rails. The apparatus may further comprise a counterbalance. The counterbalance may serve to balance load distribution when the apparatus in use and act as a storage receptacle for the first and second frame members, the beam, and the lifting device when the apparatus is disassembled.
