This invention relates to a portable lift device for moving bariatric patients. The portable lift includes a beam having a track which is sized to allow a trolley portion of a lift assembly to move therein. A bracket is removably secured at each end of the beam, whereby each bracket is configured to receive ends of two leg assemblies. Each of the four leg assemblies are individually adjustable along a longitudinal length, allowing the portable lift to conform to a multitude of surface types. Thus, a patient can be lifted by the lift assembly, moved along the beam and over a surface or obstacle by way of the trolley in the track, and deposited onto a gurney or stretcher for further movement. The portable lift is modular in nature, which allows a user to easily carry the lift in a disassembled state, and assemble the lift at any desired location.
