It will be noted that the pivotal mounting of the cylinders is such that the cylinders have their greatest leverage (i.e., exert the greatest door-opening force) when the door leafs 24, 28 are closed because the cylinders are generally perpendicular to the closed leafs. This is desirable because the load on the leafs is the greatest when they are closed due to air pressure. As the leafs begin to open and this air pressure decreases, the opening force exerted by the cylinders on the door leafs decreases and the opening speed of the leafs increases.

Like I’ve said, John, you’ve got to get the two bridge leafs to come down very slowly to a complete stop in order to trigger the tongue locks. This is what holds the two leafs of the bridge firmly in place. Otherwise, the bridge leafs will start bouncing, and once they start bouncing, you’ll never stop them from goin’ straight up in the air.
