Brand:Huazhong
Model:HZQ
The basic information of the girder transporter in precast girder yard
(1)Main feature
- safety control system, reliable by using electric and hydraulic. Concentrating the control system with over-pressure protection, and with all position limit device
- light self weight, easy to assemble, especially for curve bridge
- span-shift can be finished from 32m to 24m by moving the support legs, very conveniently

(3)Scope of application and purpose
- can bridge full span box-type prestressed concrete girder for double track special railway passenger line with straight line, curve line(radius >2500m),longitudinal gradient 20‰,32m,24m,20m equal span or changing span
- erect bridge girder at the beginning and at the end
- cross one pier to another pier by automatic shifting
- two ways to shift between bridges: carried by girder transporter and automatic transfer
(4)Working condition
- work altitude ≤2000m
- work ambient temperature:-20°C~+50°C
- the equipment will not be damaged under non work condition of -40°C extreme environment
- allowable maximum wind pressure in working condition: girder erection:6 grade cross piers: 5 grade
- allowable maximum wind pressure in non work condition:11 grade
- applicable longitudinal gradient:20‰
- adaptive curve radius: ≤2500m
- duty class of complete machine:A3, duty class of mechanism M4
- satisfy construction requirement at night, set up enough lights at night
