It composed of horizontal moving girder devices, main girders, support system, vertical moving gantry devices, horizontal moving gantry devices, hydraulic system and electrical control system.
Highway bridge is the highway bridge prestressed concrete beam tablet or beam section lifting to bridge bearing on the special construction machinery. Mainly by the beam longitudinal shift flat car assembly, girder components, support system, the longitudinal shift system, the transverse system, hydraulic system, electric control system components.
Main girder is commonly double beam truss structure. At present domestic highway bridge structure form in roughly the same, the main difference is that the longitudinal guide beam bridge form and via way. According to the longitudinal guide beam forms can be divided into single guide beam bridge and double guide beam bridge, according to the via form is divided into LunGuiShi bridge and walking machine.
(LunGuiShi bridge low gravity, weight is lighter, erection curve bridge radius is small, weight via, must be laid longitudinal shift orbit. Because of the surge in car central has great bearing reaction function in already stand naked in the middle of the LiangLiang piece, it is possible to cause damage to beam piece, the application of other load distribution method to bare beams protection, such as in the approach to walk, but also to strengthen the foundation treatment. This type of machine for more than 30 meters or less across the bridge erection. While walking to bridge construction load effect only in already stand naked beam end and bridge abutment, improve the beam body stress condition, the beam piece structure and the central force no special requirements, and hole without laying longitudinal shift orbit and weight, is gradually replaced LunGuiShi bridge. )
With the rapid development of China's highway construction, bridge structure also shows diversification trend to adapt to the skew bridge, curved bridge, dislocation bridge, heavy beam, variable beam, half picture, full of beam piece laid and two-way bridge, through the tunnel under different working conditions, such as the use requirement.
