Main technical paramters of HZQ59/80 segments assembly launching gantry
HZQ59/80 segments assembly launching gantry is used to construct Punggol Bridge in Singapore, whose construct way is: lift segment up firstly, then level it, coat epoxy resion, then lift another one up and coat it, finally tension them together.
Below are some main technical parameters:
span: 59m
max girder segments weight: 80t
| Overhead trolley lifting speed | 0～3m/min |
| Overhead trolley longitudinal moving speed | 0～15m/min |
| Girder feeding | Under the bridge |
| Power | 380V/50Hz |
| Transportation | According to situation |
| Ambient temperature/humidity | 0～40℃/90% |
| Longitudinal moving wind speed | 16m/s |
| Wind speed for lifting segments | 22m/s |
| Survival working speed | 23～40m/s |
| Max horizontal moving speed for complete machine | 0～0.5m/min |
| Complete machine longitudinal moving speed | 0～1.0m/min |
| Sling rotation | 360° |
| Segments hanging way | 4 positions for lifting beam, 3 positions for hanging beams |
