An apparatus for movably supporting a patient in an emergency medical system interiorly disposed in a helicopter is disclosed. First and second bearing blocks are slidably received on first and second upwardly extending elongated mounts. The mounts restrain any horizontal movement of the bearing blocks, while the bearing blocks cooperate to support a pallet assembly. Linear actuators are attached to the first and second bearing blocks to move each respective bearing block in a vertical direction independently of the other bearing block so as to raise and lower the entire pallet assembly or different ends thereof. Control means are provided for controlling the linear actuator and, thereby, the positions of each of the bearing blocks to permit selective positioning of the pallet assembly.
