Abstract A patient transfer apparatus comprising a wheeled base having a vertically disposed post extending upwardly therefrom. A tubular support is vertically slidably movable on the post and has a pair of pivotal arms extending therefrom in a spaced apart relationship. A third arm is secured to the tube and extends upwardly and outwardly therefrom between the pair of arms. Power means is provided for raising and lowering the tube relative to the post. The post is selectively rotatably mounted on the base to permit the precise positioning of the arms. The arms are adapted to support the chair means for transferring the patient.
