Girder Lifting Gantry
For bridge girder lifting.
Application
HSR/highway precast yards; lifting, transferring, loading box/T girders (yard only, not onto piers).
Pain points
Heavy girders; needs two machines synchronized lifting, high precision, stability, ground adaptation.
Solution
Double-girder gantry with high-precision sync; two transporters co-lift; from bed lift, transfer, load, stack; inner clearance fits girders; yard internal flow only.
