It moves, slings via hole supporting leg (4) using rear overhead traveling crane (7) lifting mechanism (6b) and move forward, until supporting leg (3) support, via hole finish in being close to.
9. the twin beams walking bridging machine that a kind of box beam erection according to claim 7 is set a roof beam in place with compatible high-speed rail list two-wire,
It is characterized by: the movement of setting a roof beam in place includes,
Step 1, beam car feeding beam: two overhead traveling cranes are run to frame box beam position, rear support leg (5) overturning, and beam car carrier beam is from bridge formation
Girder (1) abdomen is driven into machine rear end bottom, close to via hole supporting leg (4)；
Step 2, overhead traveling crane bale handle: revolution rear support leg (5) simultaneously supports, and two overhead traveling cranes move to girder (1) rear end bale handle position, lift pre-
Beam piece processed；
Step 3, the synchronous bale handle of overhead traveling crane feeding beam, Luo Liang: two overhead traveling cranes move ahead, and by being moved into the contraposition of row box beam in length and breadth, and fall Liang Zhizhi
Seat is set, and grouting is waited；
Step 4, beam car exit: beam car exits inside rear support leg (5), and return takes beam.
