The suspension hook of beam trolley catches on two the first suspension centres 31 of first group of suspension centre and unclamps and hangs in the overarm arm of right side close to one group of suspender
Beam trolley；
Step e, it moves one group of hanging beam trolley of close suspender in the overarm arm of right side and its suspension hook is made to catch on third group respectively
Then two third suspension centres 33 of suspension centre move one group of hanging beam trolley of close suspender in the overarm arm of left side and distinguish its suspension hook
Two the 6th suspension centres 36 of the 6th group of suspension centre are caught on, the hanging beam trolley 25 of third suspension centre 33 is then unclamped；
Step f, hanging beam trolley drives right side segment block to move right, and makes to hang in the overarm arm of right side close to one group of suspender
The suspension hook of beam trolley catches on two third suspension centres 33 of third group suspension centre, then unclamps two the 6th suspension centres 36 of the 6th group of suspension centre
Hanging beam trolley lifting hook；
Step g, hanging beam trolley drives right side segment block to move right, and moves hoisting overhead travelling crane along bridge formation opposite direction, makes
Right side segment block and the left side segment block lifted are located in a straight line and are located at right side segment block on the right side of crane's major girder
It hangs immediately below reinforcing bar, and hanging reinforcing bar is made to catch on sling point, unclamp hanging beam trolley lifting hook and complete right side segment block lifting.
Fig. 6~Figure 11 is the method and step of left side segment block lifting, and wherein the length of segment block 4 is 11.55m, Bridge Erector
Minimum widith between girder inside is 9.2m, and left side segment block is hung to girder or less 1.5m using suspender in Fig. 6, will be left
Side segment block traversing 0.7m to the left, is then rotated by 90 °, left side segment block length direction is consistent with crane's major girder width direction；
Mobile one group of hanging beam trolley 25 being located in 23 left and right sides overarm arm of suspender in Fig. 7, and make close in the overarm arm of left side
The suspension hook of the hanging beam trolley of suspender catches on two the second suspension centres 32 of second group of suspension centre, the hanging beam of close suspender in the overarm arm of right side
The suspension hook of trolley catches on two the 5th suspension centres 35 of the 5th group of suspension centre, rear to unclamp suspender 23, and suspender 23 moves right 0.7m to original
Position；Hanging beam trolley 25 drives left side segment block to be moved to the left 2.3m in Fig. 8, Fig. 9, so that hanging far from suspender in the overarm arm of left side
The suspension hook of beam trolley catches on two the first suspension centres 31 of first group of suspension centre, and the hanging beam trolley of close suspender hangs in the overarm arm of left side
Hook pine hook, and to two third suspension centres of third group suspension centre, 33 surface so that its suspension hook catches on third group after the 2.3m that moves right
Two third suspension centres 33 of suspension centre, close to the suspension hook pine hook of the hanging beam trolley of suspender in the overarm arm of right side, and the 0.61m that moves right
So that its suspension hook catches on two the 6th suspension centres 36 of the 6th group of suspension centre right above to the 6th suspension centre 36, close to hanging in the overarm arm of left side
The suspension hook pine hook of the hanging beam trolley of tool 23；After being moved to the left left side segment block 0.75m in Figure 10, and make close in the overarm arm of left side
The suspension hook of the hanging beam trolley of suspender catches on two four-point liftings 34 of the 4th group of suspension centre, then unclamps close in the overarm arm of right side hang
The hanging beam trolley of tool 23；After being moved to the left left side segment block 2.735m in Figure 11, left side segment block is made to be located at a crane's major girder left side
Side is hung immediately below reinforcing bar, and hanging reinforcing bar is made to catch on sling point 37, is unclamped hanging beam trolley lifting hook and is completed left side segment block lifting；
Since the supporting leg 22 of Bridge Erector stops so that the suspension hook of hanging beam trolley can only be in overarm arm 24 during catching on hanging crossbeam 3
It is mobile positioned at the side of supporting leg 22, that is, the suspension hook of the hanging beam trolley of 22 two sides of supporting leg is distributed in during catching on hanging crossbeam 3
Mobile no more than supporting leg, and movement is only defined within crane's major girder, therefore is hung using the multiple suspension centres of setting and setting
Beam trolley adjusts segment block position, to complete the lifting of left side segment block and right side segment block.
The method that the suspending method of right side segment block is lifted with left side segment block, right side segment block hangs in hoisting process
The axial direction for filling the opposite crane's major girder length direction of the lifting with left side segment block is in mirror symmetry, and Figure 12 is section on the left of being finally
