500 t Gantry Crane for Ma’anshan Bridge Steel-Tower Assembly
A 500 t gantry supported the Z3 steel-tower assembly acceptance within a package of more than ten bridge-project cranes.
The project and its handling task.
Henan Mine Crane supplied more than ten crane units, including 500 t and 400 t gantry equipment, for the Ma’anshan Yangtze River road–rail bridge project.
A 500 t gantry supported China Railway Jiuqiao’s first-round overall assembly acceptance for the Z3 steel tower. The crane package handles main steel-tower sections and other large bridge structures, linking fabrication and assembly lifts to the project sequence.
Move major steel-tower sections through bridge fabrication and assembly.
Large cable-stayed-bridge tower modules need heavy controlled lifts at fabrication and preassembly stations before erection.
Confirm lifting points and support frames for each steel section.
Assign gantry paths and waiting zones in the fabrication yard.
Position sections for trial assembly and inspection before release.

What to compare with your own project.
Match the project configuration to your load, layout and operating sequence before selecting a crane package.
| Design area | This project configuration | Define for your site |
|---|---|---|
| Named crane capacity | 500 t | Steel section dimensions and mass. Define the required operating envelope and acceptance checks in your technical brief. |
| Additional named capacity | 400 t | Yard/runway plan. Define the required operating envelope and acceptance checks in your technical brief. |
| Package scope | More than 10 crane units | Concurrent crane schedule. Define the required operating envelope and acceptance checks in your technical brief. |
| Application | Steel-tower and bridge-structure handling | Trial-assembly tolerances. Define the required operating envelope and acceptance checks in your technical brief. |
| Milestone | Z3 first-round overall assembly acceptance | Steel section dimensions and mass. Define the required operating envelope and acceptance checks in your technical brief. |

Assembly acceptance milestone completed.
The Z3 steel-tower first-round overall assembly acceptance was completed with support from the 500 t gantry. The broader crane package serves structural handling across the bridge project.
For a similar project, size the gantry fleet from the heaviest tower section and site layout. Coordinate several gantries so fabrication, trial assembly and dispatch can proceed without conflicting load paths.
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.
Prepare a comparable crane quotation.
Share the load schedule and site drawings. Size the gantry fleet from the heaviest tower section and site layout. Coordinate several gantries so fabrication, trial assembly and dispatch can proceed without conflicting load paths.
We can quote a single crane or a coordinated fleet. The offer sets out the destination standards, required certificates and inspection records, manufacturing programme after drawing approval, shipment, installation support and agreed acceptance scope.

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. Steel section dimensions and 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 trial-assembly tolerances in the technical review.
