700t Gantry Crane for Zhangjinggao Yangtze River Bridge Construction
Featured project view of the 700t heavy-duty gantry crane manufactured for main steel-tower structure handling.
Major bridge projects require lifting systems capable of moving extremely heavy steel-tower sections and structural assemblies over large fabrication and erection areas. Buyers must evaluate not only rated capacity, but also span, lifting height, hook arrangement, runway loads, structural stiffness and the project erection sequence.
Henan Mine Crane manufactured a 700t gantry crane for the Zhangjinggao Yangtze River Bridge steel-tower construction project. The referenced crane passed type testing and is part of a multi-crane package used for lifting the main steel tower and other bridge structures.
Project Background
The Zhangjinggao project includes very large bridge towers, with the source describing a 350 m main tower. Heavy steel-tower fabrication and pre-assembly require a crane that can cover large working areas while handling high-value structural sections.
The source describes the project crane as a large-capacity, large-span and high-lifting-height engineering gantry crane developed with modern computer technology, advanced configurations, new materials and new manufacturing processes.
For a similar bridge project, the crane must be engineered together with the fabrication yard, runway, erection method and maximum structural module dimensions.
Customer Challenges
- Handling very heavy steel-tower and bridge structural modules.
- Providing large working coverage across a bridge fabrication or assembly yard.
- Maintaining adequate lifting height for tall steel-tower sections and lifting frames.
- Controlling crane dead weight and wheel loads for the project runway structure.
- Coordinating several lifting points, rigging systems and erection sequences.
- Passing project-specific testing and acceptance before critical bridge erection work.
Henan Mine Crane Solution
Henan Mine Crane configured the referenced project around a 700t heavy engineering gantry crane used for main steel-tower structure lifting. The structural design combines high capacity with the large span and lifting height required by bridge construction.
The source emphasizes lightweight, generalized, energy-conscious and high-technology design concepts. For a new project, the final bridge, leg, trolley and hoisting configuration should be calculated from the actual steel-section weight, lifting points, center of gravity and runway geometry.
Type testing and project acceptance can be planned before delivery so that heavy lifting, travel, braking and safety functions are verified against the agreed technical specification.

Key Technical Features
700t-Class Heavy Lifting
The referenced crane is designed for ultra-heavy steel-tower and bridge-structure handling.
Large-Span Project Coverage
A gantry configuration can cover wide fabrication and assembly areas without relying on a building runway.
High Lifting Height
The source specifically identifies high lifting height as a key feature of the engineering crane.
Lightweight Engineering
Structural optimization can reduce unnecessary crane dead weight while maintaining required strength and stiffness.
Project-Specific Testing
Type testing and acceptance help verify the crane before critical bridge erection operations.
Application Scenarios
| Steel Tower Fabrication Yards |
Lifting and pre-assembly of large bridge tower sections. |
| Bridge Erection Projects |
Heavy structural handling during major river-crossing construction. |
| Large Infrastructure Yards |
Outdoor lifting where wide gantry coverage is required. |
| Heavy Steel Structure Assembly |
Transfer and positioning of very large fabricated modules. |
Why Choose Henan Mine Crane
- Henan Mine Crane can engineer the crane from the actual bridge module and erection method rather than only from nominal tonnage.
- Span, lifting height, wheel loads and runway loads can be coordinated with the project civil design.
- Heavy-duty hoisting, braking and safety systems can be included in project-specific testing and acceptance.
- Large bridge projects can be supplied as multi-crane packages with coordinated delivery and commissioning.
Frequently Asked Questions
What information is needed for a 700t bridge gantry crane quotation?
Provide maximum module weight, lifting-beam and rigging weight, module dimensions, center of gravity, lifting points, span, lifting height, runway length, rail and foundation information, duty cycle, required speeds and erection sequence.
Why is crane dead weight important on bridge-construction gantries?
Lower unnecessary dead weight can reduce wheel loads and civil-structure demand, but structural stiffness and fatigue requirements must still be fully satisfied.
Can the crane be tested before bridge erection begins?
Yes. Factory and site acceptance plans can include no-load, functional, safety and heavy-load testing according to the project specification.
