en.Wedoany.com Reported - The main girder positioning section of the 1600-ton gantry crane project at Jiangnan Shipyard, constructed by China's Nantong Zhenhua Heavy Industries, has successfully completed the turnover, closure, and hoisting operation. The successful implementation of this critical hoisting construction marks the project's official entry into a new phase of overall installation, laying a solid foundation for subsequent complete machine assembly, equipment commissioning, and operational deployment.
On October 16, 2025, Jiangnan Shipyard and Zhenhua Heavy Industries signed the construction contract for the 1600-ton gantry crane as part of the No. 3 Dock lifting capacity enhancement project; on December 6, the project commenced steel cutting, with a construction and delivery period of 10 months.
The Jiangnan Shipyard 1600-ton gantry crane project features a rail gauge exceeding 200 meters and a beam bottom elevation over 90 meters, utilizing a single main girder structural design. The equipment is primarily composed of the main girder portal frame steel structure, two 450-ton upper trolleys arranged on the same rail, one 500-ton lower trolley, crane traveling mechanism, a complete electrical control system, and various supporting functional systems. It features a rational structural layout and stable, reliable operation, capable of meeting the high-precision, large-tonnage hoisting requirements for large and heavy components.
The 1600T gantry crane project currently under construction is another significant shipbuilding tool jointly created by Zhenhua Heavy Industries and Jiangnan Shipyard.
Upon completion, this project will be installed at Jiangnan Shipyard. Once operational, it will significantly enhance the hoisting efficiency of large dock blocks and heavy equipment, optimize the shipbuilding production process, and assist Jiangnan Shipyard in achieving synchronous construction of 8 batches across two lines in one dock, greatly strengthening Jiangnan Shipyard's construction capabilities.
