(m) After the bridge is in position on the trailer, disengage the tongue from the lifting diaphragm
of the bridge.
(n) Back the launcher away from the bridge using a ground guide.
NOTE
The bridge should be secured to avoid any shifting or sliding during transport, thereby
causing damage to the bridge. The maximum height of the bridge (Class 60 or Class 70)
on the trailer from the ground is approximately 13 feet. Since the bridge is wider than the
eight-foot wide trailer bed, this load is classified as an OVERSIZE WIDE LOAD. To
transport this load will require escort vehicles both front and rear for the transport of the
folded bridge.
(o) Secure bridge in position on the trailer as shown below.
