ABSTRACT:
A compact, lightweight, power lifting unit assists the operator of a mobile patient transporter in raising or lowering the patient bed to the desired height required in transporting or transferring a patient. The power lifting unit may also be used to "collapse" the transporter. The power lifting unit uses a ball screw and ball nut to convert the rotary motion of an electric motor to the linear motion necessary to drive a tension arm and raise or lower the transporter. The power lifting unit is adaptable and may be installed on virtually any existing transporter.
