3) axial advancement of the maintenance chassis along box beam (3), is drawn by electric hoist, workmen via the first cat ladder (1.4) and
3rd cat ladder (1.5) is carried out into the operation platform of bottom boom frame (4) afterwards via the second cat ladder (2.4) and the 4th cat ladder (2.5)
Box girder construction；
4) one, being completed across after box girder construction, maintenance chassis being rested in by bridge pier, the first truss (1) and the second purlin are fixed temporarily
Frame (2), opens alignment pin (20) and fixed pin shaft (17), is opened after transferring bottom boom frame (4) to vertical state by hoist engine (5)
Rope clamp (8), the steel wire rope of man-hour manually hand-held first (6) bypasses box beam bearing (28), is located at the first steel wire rope (6) and bottom boom frame (4)
The same side, reach maintenance chassis by after bridge pier (29), fixing the first truss (1) and the second truss (2) temporarily, man-hour manually hand-held the
One steel wire rope (6) bypasses box beam bearing (28) and returns to the second truss (2) side, and the first steel wire rope (6) and the are connected by rope clamp (8)
Two steel wire ropes (7), steel wire rope is tightened up using hoist engine (5), and lifting bottom boom frame (4) plugs alignment pin (20) to horizontality
With fixed pin shaft (17), the first truss (1), the second truss (2) and bottom boom frame (4) is set to form hands-off operation platform.
5) 3-4, are repeated the above steps until whole box girder constructions is completed.
8. a kind of open-close type as claimed in claim 7 crosses the method for work that pier box beam overhauls construction trolley, it is characterised in that：Institute
State bridge pier (29) for monoblock type bridge pier, the box beam (3) be the separation type box girder being set up on monoblock type bridge pier when, can be in entirety
Walking track (32) is laid in the box beam (3) of formula bridge pier both sides respectively and frame is distinguished in the box beam (3) of monoblock type bridge pier both sides
If maintenance chassis, to the box beam (3) of monoblock type bridge pier both sides while carrying out maintenance construction.
