The disclosed lift/transfer mechanisms have pairs of boom arms upstanding from the top surface of a patient gurney, the arms being of sufficient height and length to have the free arm ends thereof in different operative positions overlie the top surface of the gurney or an adjacent transfer support. Each boom arm end has an underlying hook for making a releasible connection via flexible straps or the like to the patient board. In one embodiment, a winch is carried on the boom arm end section, and a lift strap is released or retracted by winch operation to raise and lower boom arm hook to which the patient board is connected, and thus raise or lower the patient board and to suspend the board from the boom arms. Boom arm rotation between the operative positions shifts the suspended patient board laterally between the gurney and transfer support. In another embodiment, the boom arms are articulated to raise and lower the patient board, and further are supported on slides that can be moved laterally of the gurney top surface to shift the suspended patient board between the operative positions overlying the gurney and the transfer support.
