72 m-Span Gantry Crane for Jianzhou Bridge Construction
A 72 m-span crane handled steel bridge construction across the Tuojiang River and an adjacent road corridor.

The project and its handling task.
Henan Mine Crane’s 72 m-span crane served the Jianzhou Bridge construction project in Jianyang. The equipment crossed the Tuojiang River and the Airport Avenue corridor during the steel bridge works.
The bridge uses a fully welded, variable-section continuous steel box-girder design and has a total length of 580.5 m. The bridge project’s geometry created demanding structural lifting requirements, and the equipment was selected after technical discussion and evaluation.
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.
Plan load pickup and temporary support for the changing box-girder section.
Verify clearance over roadway and site obstacles.
Align the steel segment with the next assembly support.
Align the steel segment with the next assembly support.

Bridge construction completed.
The crane supported construction of the completed Jianzhou Bridge. Its wide lifting coverage addressed the river and road-corridor geometry of the steel-structure project.
For a similar project, 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.
Prepare a comparable crane quotation.

Questions before specifying a similar crane.
Can the same project crane be supplied for my site?
We customize the capacity, span, lifting height, attachment and controls to the load, building or yard layout and operating cycle. Box-girder segment mass is one of the inputs to review before final equipment selection.
How are certification, quantity and lead time agreed?
Single-crane and fleet enquiries are welcome. Define the destination and required standards in the enquiry. The project offer confirms certification and inspection documents, the quantity, drawing approval and manufacturing schedule, with the shipping and site-service boundaries.
What should acceptance and after-sales support include?
Agree the inspection plan, representative load and functional tests, operator training, maintenance instructions, spare-parts scope and fault-recovery procedures. For this application, include assembly support and alignment method in the technical review.
Planning a similar lifting project?
Send your layout, load and operating requirements. We can develop a customized crane package and delivery scope for your site.
