Notes:
1. Table shows load (MLC) capacity based on one vehicle positioned on the raft centerline and centered on the deck. The values
shown for 3-/4-/5 bay rafts apply for wheeled or tracked vehicles. The values shown for a 6-bay raft apply for track/wheel vehicles
as shown.
2. Two bridge boats are required for propulsion with any raft in the table.
3. This configuration is to be used only where current velocities in loading and unloading areas are 5 fps or less.
4. Ratings apply only with bottom of ramp ends raised 1 foot clear of water. Ramps raised for loading must be lowered before raft
is underway.

Secure raft to shore.
Open pump access cover (20) and set pump control valve (21) to TRAFFIC position, close vent valve (22),
and close cover (20).
Repeat Step (i) for remaining pump.
Lower approach ramps (23) and unload vehicles.
