  • Patent number: 5459891
    Abstract: An invalid lift and transport apparatus for safely lifting and transporting bedridden or wheelchair bound individuals with a minimum of effort and assistance is disclosed. The apparatus includes a movable mast assembly powered by a remote hydraulic pump. The mast assembly has an upright mast rotatable about a substantially vertical axis and a hydraulically extensible boom, for supporting an invalid carrying sling, pivotally joined thereto. A lift cylinder, joining the lower portion of the mast with the boom, is provided for raising and lowering the boom. A hand-held controller permits the invalid individual or attendant to extend, retract, raise, and lower the boom by selectively actuating the hydraulic components with the touch of a button. The mast may be similarly rotated. In operation, the sling may be readily moved to position an invalid seated therein to practically any position within the reach of the boom with a minimum of physical effort.
