300 t Overhead Crane for Zhangjinggao Bridge Fabrication
A 300 t modular double-girder overhead crane provides heavy bridge-component handling with full variable-frequency control.
The project and its handling task.
Henan Mine Crane supplied a 300 t new-design double-girder overhead crane for the Zhangjinggao Yangtze River Bridge project. The equipment forms part of the lifting support for large bridge components.
Modular design, a lightweight structural arrangement, hardened-tooth reducers and integrated electrical design were combined in the crane package. Full variable-frequency control supports smooth motion and accurate positioning, with interfaces reserved for subsequent equipment upgrades.
Move steel-bridge assemblies efficiently within a production bay.
Bridge fabrication needs heavy lifts that remain smooth near weld fixtures, assembly jigs and adjacent teams.
Identify lift points and temporary stiffening or supports.
Use controlled bridge travel and clear working zones.
Slow the movement for alignment and verify support before detaching.

Project-site application.
The crane was applied at the Zhangjinggao bridge project. Its heavy lifting capacity and modular motion-control arrangement support bridge-component handling.
For a similar project, plan a 300 t bridge crane around the bay span, large-section pickup points and fabrication sequence. Modular construction, full variable-frequency control and service access can support positioning and later upgrades.
Continue from the project to the right crane family.
Use the project as a reference and specify the crane against your own yard layout and cargo.

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. Section and rigging schedule 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 drive and service requirements in the technical review.
