Shipbuilding gantry cranes (commonly referred to as gantry cranes) are typically employed in shipbuilding, wind power, and offshore engineering industries. Primarily used for product hoisting, assembly, and final assembly operations, they offer multiple functions including lifting, transporting, and segmental aerial rotation. Their role in segmental rotation and hull assembly is particularly crucial in shipbuilding operations. The crane primarily consists of a portal structure, upper trolley, lower trolley, main travel mechanism, electrical control system, maintenance crane, boarding elevator, power supply cable reel, wind protection device, and alignment correction device. The shipbuilding industry predominantly employs upper and lower traversing trolleys. In wind power and offshore engineering, both upper/lower traversing and parallel trolley configurations are utilized, depending on operational requirements. Design, manufacturing, and inspection comply with international and domestic standards including FEM, DIN, IEC, AWS, and GB.

Common product capacities include 200 t, 300 t, 400 t, 500 t, 600 t, 800 t, 1000 t, 1200 t, 1500 t, 2000 t, 2500 t, 3000 t, and 3600 t. Weihua Shipbuilding Gantry Cranes incorporate multiple leading technologies, utilizing variable frequency intelligent control systems to collect real-time operational data, monitor equipment status, and ensure maintenance safety. With superior overall performance, they represent a professional, efficient, and secure equipment solution. The world's first 3600t shipbuilding gantry crane achieved a new breakthrough in lifting capacity.
 

1. Floating Crane Installation of Xinhantong 500t Gantry Crane

Project Scope: Weihua Marine Engineering employed floating crane technology for the first time to install a 500t-153m gantry crane at Xinhantong Shipbuilding Heavy Industry Co., Ltd. The main girder weighed 2,100 tons, with the entire crane weighing 6,000 tons.

Technical Breakthrough: Through coordinated operations of 1000t and 2500t floating cranes, the project completed rigid/flexible leg rotation, main girder unloading, and upper/lower trolley installation within 4 days, demonstrating high-efficiency adaptability in challenging environments.

Functional Features: Dual-girder design with upper trolley capacity of 2×175 tons and lower trolley capacity of 250 tons. Capable of segmental aerial rotation and large-span lifting, meeting requirements for large ship section assembly.
