loading operation.
(c) Raise the tongue into position for engaging the lifting diaphragm of the bridge.
(d) Mate the tongue to the launching diaphragm on the bridge, ensuring that the pintles of the

located on top of the diaphragm plate.

Coordinating the movement of these two cylinders lessens the pressure on the trailer and
reduces the chance for blowing out trailer tires.

(i) With the bridge seated on the launcher, ensure that it is secured in position with the hold down
chains for transport.
