500t Gantry Crane for Maanshan Yangtze River Bridge Steel Tower

Large cable-stayed bridge projects require high-capacity gantry cranes for steel-tower section assembly, pre-erection and heavy structural transfer. Procurement must consider the heaviest fabricated module, lifting points, yard span, rail loads and assembly workflow.

Henan Mine Crane supplied a 500t gantry crane for the Maanshan Yangtze River Road-Rail Bridge project. The source states that more than 10 crane sets, including 500t and 400t units, were used for lifting the main steel tower and other bridge structures.

Project Background

The project uses a three-tower, two-main-span bridge arrangement, creating substantial steel-tower fabrication and assembly work before final erection.

A multi-crane package allows heavy primary lifts to be handled by the largest cranes while other cranes support subassembly, transfer and auxiliary work. For buyers, this can be more efficient than oversizing every crane position.

Customer Challenges

• Handling large steel-tower sections weighing hundreds of tonnes.
• Coordinating primary and auxiliary cranes across the bridge fabrication yard.
• Providing sufficient span and lifting height around tall structural modules.
• Maintaining accurate structural alignment during pre-assembly.
• Planning runway and foundation loads for several heavy gantry cranes.
• Scheduling crane delivery around bridge-fabrication milestones.

Henan Mine Crane Solution

The referenced project uses 500t and 400t-class cranes as part of a package exceeding 10 crane sets. The 500t gantry crane supports main steel-tower assembly and heavy structural lifting.

For a similar bridge project, Henan Mine Crane can divide the crane schedule by heavy-lift, assembly, transfer and auxiliary duties. This helps match capacity and lifting configuration to each production position.

Crane structure, trolley arrangement, hook approach, travel speeds and runway loads should be engineered from the steel-section drawings and yard layout.

Key Technical Features

500t Heavy Structural Lifting

The referenced crane supports very large bridge steel-tower modules.

Multi-Crane Project Package

Several capacities can be coordinated across fabrication and assembly tasks.

Outdoor Gantry Coverage

Gantry travel provides wide working coverage without depending on a factory building.

Project-Specific Rigging

Hook arrangement and lifting beams can be engineered around structural module lifting points.

Construction Schedule Integration

Crane manufacturing and commissioning can be aligned with bridge-fabrication milestones.

Application Scenarios

Why Choose Henan Mine Crane

• Henan Mine Crane can provide several crane capacities as one coordinated bridge-construction package.
• Capacity selection is based on actual module weights and auxiliary lifting duties.
• Runway loads and gantry geometry can be coordinated with the fabrication-yard civil works.
• Project-specific lifting beams, hook arrangements and acceptance requirements can be included.

Frequently Asked Questions

When is a 500t gantry crane needed in bridge construction?

It is suitable when the heaviest steel-tower or bridge structural modules, together with lifting beams and rigging, require very high lifting capacity.

Should every crane in the bridge yard have the same capacity?

No. Heavy primary lifts, subassembly and general transfer usually have different load requirements. A mixed-capacity crane schedule can be more economical.

What drawings are required for quotation?

Provide steel module drawings, maximum weights, lifting points, yard layout, span, lifting height, runway length, rail/foundation data and construction schedule.

Request A Construction Engineering Crane Solution

Send your maximum load, structure or equipment drawings, project layout, span, lifting height, runway information, operating cycle and construction schedule. Henan Mine Crane engineers will review the application and prepare a project-specific crane proposal.
