of Folding Frame type
With the patented TTS Folding Frame bow ramp arrangement the collision bulkhead door can be completely separated from the rest of the ramp. This implies that no part connected to the door will extend forward of the correct position for the collision bulkhead. A steel frame is positioned forward of the collision bulkhead door and controls the folding movement through hinge connections with the outer part of the ramp. In the fully outfolded position the frame, together with the outer section, forms the load carrying structure.
