What’re the measuring, positioning and field engineering of bridge girder launcher?
The bridge girder launcher is installed on the bridge head or roadbed with area length 100m x width 12m
on the abutment which will be constructed. The assembly site requires certain working surface, the roadbed
should have enough bearing capacity, general bearing capacity ≮1.18kg/cm²,satisfy the demands of installing
bridge girder launcher and carrying girders; according to dimension in installation drawing, measure the position
of longitudinal rail centre line, the central distance, front support leg, middle support leg, gantry crane support leg
and draw the position line on the installation site.
