Lock rollers and disconnect push bar. (i) Raise or lower rear roller beam as needed to bring rear of bridge to a height that will make assembly of next bays as easy as possible and level capsill and rear roller beams. (9) Add bays 14 thru 22 including sway braces. (10) Place one deck unit in the third recess of bays 17 and 21. (11) Complete end of bridge (para. 4-9b.). (12) Add twenty deck units and six curbs as counterweight. Position a flat bed vehicle close to the end of bridge and use personnel standing on vehicle to transfer the counterweight from ground level up to personnel on the end of bridge. NOTE The launch of the bridge is done with a vehicle and long push bar connected to the bankseat beam (para. 4-18c.). Once this vehicle Is connected to bridge it will not be disconnected until far bank end of bridge has been lowered to ground. (13) Connect vehicle and push bar to bridge (para. 4-1&c). (14) Unlock rollers. Launch bridge to panel point 10p7 (over CRB). This puts the CG over CRB. (15) Do not lock rollers; the vehicle is used to hold the bridge in place. (16) Set up landing roller pedestal Mk1 (para. 4-15a.) on far bank and check that LZ6 or higher is over the center of LRP rollers (para. 4-4). CAUTION A landing zone number higher than the given LZ is always permitted. Never use an LZ number lower than that given for the bridge being constructed. (17) Continue launch until panel point 19p5 is over capsill roller beam. NOTE Nose sections (light and heavy) can be removed during launch after they have passed the center of the landing roller. It is important to remember that at least 5 ft (1.5 m) of nose section must extend beyond the landing at all times. (18) Remove nose sections that have passed the landing roller pedestal. Leave the three nose sections in place. These sections will be removed after the far bank end of bridge has been lowered to the ground. 6-47
