6. Main design requirements of Upstroke Movable Support System

The machine can meet the needs of the 32m, 24m full-span box girder erection in the railway passenger double line project.
While the machine needs to erect the continuous girder or transferring, just to expand the side mould frame and base mould.
The machine moves with the walking hydraulic jacking system, replacing the support legs with the steel rope traction method.
The single main girder structure with a rigid and flexible support leg as the supporting.
The weight-casting capacity: about 900t
Max. anti force at working: 5805KN
Applicable curve radius: R>2000m
Applicable longitudinal slope/ transverse slope: 2%/2%
The deflection of main girder: 1/700
