It is fixed；Rear support leg and the lifting lug of girder steel top surface are anchored；Gantry crane on erection crane is between rear support leg and front leg strut；
(3) 1# girder steel is lifted：Gantry crane move into heart line from erection crane front leg strut 3800mm at, the gantry crane center
Line refers to the cut-off rule that the longitudinal axis along load bearing beam does gantry crane；Then starting hoist engine transfers suspender, lifts by crane 1# girder steel
After section to design mounting height, hoist engine is locked；
(4) gantry crane is advanced again into from supporting leg 500mm；1# girder steel is docked with 0# girder steel, 1# girder steel suspension cable is installed,
And carry out first time tensioning；
(5) floorings on 1# girder steel are installed：Gantry crane continues to move along between front leg strut and girder front end, and gantry crane
Away from front leg strut 1755mm；Floorings are transported on 1# beam with beam car, is first lifted jointly by two electric blocks and is located at oblique pull
Intermediate floorings between rope；Floorings on the outside of two suspension cables are lifted by single motor cucurbit, on the outside of the suspension cable of lifting left side
When floorings, an electric block is first moved at the suspension cable of right side and is caught on suspension hook the erection crane master of lower section along load bearing beam
Beam is sling floorings by another electric block and is moved on the outside of the suspension cable of left side, and floorings are installed to designated position；So
Lift floorings on the outside of the suspension cable of right side in the same way afterwards；
(6) after floorings are installed, gantry crane moves back 1255mm, at from front leg strut 500mm；
(7) release the Limit screw between auxiliary leg and girder, manually auxiliary leg be pushed to close to girder front end, then with master
Beam Limit screw temporary locking；
(8) anchoring between rear support leg and girder lifting lug is released；
(9) pipe bending cylinder for starting front leg strut, by girder pushing tow 6m forward；During girder moves forward, girder top
Gantry crane, which synchronizes, to be moved backward；
(10) Limit screw of auxiliary leg and girder is released again, and after auxiliary leg is pushed 2m forward, with girder limit
Position screw lock；
(11) start the pipe bending cylinder of front leg strut for girder pushing tow 2m further along, in girder moving process, top gantry crane is synchronous
It moves backward；
(12) (11) are arrived by step (9), girder moves forward in place；Rear support leg and girder lifting lug are anchored, 1# girder steel is carried out
On suspension cable two times tensioning, then lift the floorings on next girder steel and girder steel, by step (3) to (11) circulation construction,
Until completing the lifting of all girder steels and floorings.
