INFRASTRUCTURE / LIFTING SOLUTIONS
72 m Bridge Span Gantry Lifting Solution
A long bridge segment may need a crane to span roads, river-adjacent work and wide temporary assembly zones.

THE LIFTING SOLUTION
Cover a long steel-box-girder work area with stable crane travel.
A long bridge segment may need a crane to span roads, river-adjacent work and wide temporary assembly zones.
Set the 72 m crane span from the box-girder fabrication route and site obstructions. Check runway alignment, wind exposure, rigging and placement sequence before any heavy segment is moved.
HANDLING SEQUENCE
How the solution works.
Follow the load through the operation to see where lifting equipment, tooling and controls must work together.
Cross the work zone
Verify clearance over roadway and site obstacles.
Land the lift
Align the steel segment with the next assembly support.
ENGINEERING DECISIONS
What determines the final configuration?
These choices affect safety, process fit and the operating life of the installation.
Long-span stiffness
Check deflection and wheel loads under the heaviest segment.
Outdoor conditions
Define weather limits and protected personnel routes.

PROJECT 01
Jianzhou Bridge construction
A 72 m-span crane supported construction of the 580.5 m Jianzhou Bridge, which uses a variable-section continuous welded steel-box girder.
RELEVANT EQUIPMENT
Equipment options for this solution.
These product families support the handling tasks above. The final crane and attachment are selected from the site brief.
SPECIFICATION BRIEF
What we need to size your crane.
Send the operating brief and the relevant layout drawings. The resulting proposal can address capacity, geometry, duty, controls, installation interface and safety requirements as one system.
