JQSS900 inner tunnel bridge-erecting crane can complete box girder erection work with a transporting work vehicle. In addition to the standard frame beam operations, JQSS900 inner tunnel bridge-erecting crane can also conduct the construction of initial and terminal span erection, curve erection, non-standard beam erection, gate gier erection, variable span erection and bridge erection such as span continuous beam, bond beam, continual rigid frame and simply supported continuous erection and
Advantage:
When crossing the hole, front supports of bridge erecting crane should be connected to erected beam hole. If there are continuous beams and bridge abutment, it is necessary to punch and connect to the transporting and erecting equipment. In addition, it has no harm to the roadbed and bridge floor. Working with no other auxiliary equipment, it can be operated to site transfer, head back, transport concrete box girder, cross railway passenger dedicated double line and has no interference to the finished projects, easily and fast to finish the task of erection of initial and terminal span. It is not necessary to have extra operation on abutment in advance, including embedded part and punching, etc.
