TJ180L Bridge-Erecting Machine Main Applications It’sused to erect the T-girders (girders 2201, 2101, and 2103 for common bridges)and girder 9753 for special bridges for ≤200km/h mixed passenger and freightnew and renovated railways.
Thisbridge-erecting machine adopts wheeled through-hole mode and can mechanicallytraverse the girder segments in full amplitude to realize one-time properplacement of girder segments.
Technical Features Thedouble-girder structure ensures high carrying capacity of main girders and goodlateral stability and high safety of machine.
Thelarge-boom type through-hole mode realizes one-time orientation of frontoutriggers and high through-hole efficiency.
Thethrough-hole is driven by rear outrigger tires and middle outrigger carrierwheel to realize high reliability.
Thefront outriggers are telescoping in two stages during the operations of firstand last spans, requiring no disassembling operation.
