The hanging basket generally adopts universal rods, Bailey truss and beam in the group together, complex structure, high quality. The rhombic hanging basket and the triangle hanging basket are often inconvenient to operate, and have the advantages of simple structure, few nodes, small deformation, convenient operation, etc..
Prestressed concrete continuous beam bridge, continuous rigid frame bridge span and span rivers, valleys, so the main use of cantilever pouring construction. Cantilever pouring method refers to the construction of the bridge on both sides of the working platform, a balanced section to the middle of the cantilever pouring cement concrete beam, and the construction of the application of prestressing. The main equipment is a pair of walking hanging basket, pull anchor in Zhang and pier has connected mobile beam on the whole hanging basket, and binding steel formwork, pouring concrete, prestress are carried out on the. After the completion of the construction of this section, the hanging basket symmetrical move forward a section, the next pair of beam section construction, in advance, until the cantilever beam section pouring completed.
