Gantry Cranes for Changtai Bridge Caisson Excavation
Multiple gantry cranes support steel-caisson excavation in coordination with robotic dredging equipment.
The project and its handling task.
Henan Mine Crane supplied multiple gantry cranes for the Changtai Yangtze River Bridge construction project. The cranes work within the steel-caisson excavation and sinking process.
The handling arrangement is coordinated with intelligent cutter-suction and other excavation equipment for automatic soil removal from individual caisson cells. The crane task must follow the excavation sequence and the interfaces between the caisson, lifting equipment and spoil-removal route.
Coordinate gantry lifting with automated caisson excavation.
A large bridge caisson needs continuous spoil removal from confined cells without blocking the excavation equipment or surface logistics.
Confirm container or grab interface at the excavation point.
Keep the vertical path separated from personnel and equipment.
Route spoil to a vehicle or stockpile without interrupting the next excavation cycle.

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 |
|---|---|---|
| Equipment scope | Multiple gantry cranes | Spoil load and container size. Define the required operating envelope and acceptance checks in your technical brief. |
| Construction task | Steel-caisson excavation and sinking | Caisson cell geometry. Define the required operating envelope and acceptance checks in your technical brief. |
| Process interface | Intelligent cutter-suction and soil-removal equipment | Temporary rail/support design. Define the required operating envelope and acceptance checks in your technical brief. |
| Operating arrangement | Coordinated handling for individual caisson cells | Robot-to-crane sequencing. Define the required operating envelope and acceptance checks in your technical brief. |

Bridge-construction application.
The supplied gantries support excavation conditions for the bridge’s steel-caisson sinking process. Their project role links crane handling with the foundation-construction equipment and work sequence.
For a similar project, place gantries over the caisson work zone and define how each spoil container is presented by the excavation system, lifted and discharged. Coordinate crane tasks with the automated cutter-suction equipment and caisson sinking sequence.
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. Place gantries over the caisson work zone and define how each spoil container is presented by the excavation system, lifted and discharged. Coordinate crane tasks with the automated cutter-suction equipment and caisson sinking sequence.
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. Spoil load and container size 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 robot-to-crane sequencing in the technical review.
