To install the crane span before installation, camber, level of metal structure of main girder bending, trolley rail height difference, gauge deviation, diagonal bridge survey.
Use pedal to move a gauge tap , handle bright metal chopping the head the bright metal being in progress copying, operation is convenient and rapid , stability , safety are reliable.
