bridge building cranes

1. girder carrier carrys segments to centain position and the bridge building crane lifts and suspends segments;

2. lift and suspend last segment in one span;

3. initial positioning;

4. application of adhesive;

5. accurate positioning;

6. temporary tension;

7. add steel cable strands;

8. install clip for permanent pre-stress tensioning;
