A loading ramp having an elongated frame with guideways along its length on opposite side thereof. A moving panel having rollers at its front and rear adapted to roll along die guideways of the ramp to roll the panel along the length of the elongated frame. A table mounted at one end to the moving panel and support means to support the table at its other end out away from the panel. A loading bracket for mounting in the doorway of an aircraft and adapted to receive the upper end of the elongated frame to provide a ramp from the ground to the doorway of the aircraft. A power mechanism for powering the panel and connecting table upward and downward along the frame from adjacent the ground to the doorway of the aircraft. The supporting members of the table acting to support the outer end of the table approximately away from the ramp and approximately horizontal as the power mechanism powers the table and panel upward and downward on the ramp to enable a stretcher to be placed on the table and raised from the ground into the doorway of the aircraft while approximately horizontal to the ground.

The invention comprises a stretcher. The stretcher has an elongated rectangular frame and a U shaped frame with the ends of its legs pivotally mounted to the inside of the rectangular frame to pivot from a flush position inside and parallel with the rectangular frame to an upward angular position in relation to the rectangular frame to serve as a back rest for a patient upon the stretcher. A fluid actuated piston and cylinder are pivotally connected between the rectangular frame and the pivotable U frame to pivot the U frame to an upward angle relative to the rectangular frame. Slidable panels are slidably mounted on the U frame and rectangular frame to slide laterally away from the frame to provide an adjustable arm rest for a patient upon the stretcher.
