For shipbuilding projects requiring wide operating ranges and medium lifting loads, the single girder shipbuilding gantry crane provides an economical and efficient lifting solution with excellent structural strength, stable operation, and reliable performance. For heavier ship components and more demanding marine construction tasks, the double girder configuration offers greater lifting capacity, enhanced rigidity, and improved load-bearing capability.
The shipbuilding gantry crane consists of a robust gantry structure, upper and lower lifting trolleys, trolley traveling mechanisms, electrical control system, maintenance platforms, lubrication system, and operator access equipment. Designed for continuous outdoor service, it ensures efficient and stable lifting operations throughout the ship manufacturing process, including steel fabrication, large component transfer, and hull block installation.
Safety Protection System
Shipbuilding gantry cranes are equipped with comprehensive safety protection devices to ensure accurate operation, prevent potential risks, and maintain reliable performance under demanding shipyard working conditions.
Main safety features include:
      • Rail clamps or wheel braking systems
      • Wind speed and wind direction monitoring devices
      • Overload protection and load limiting systems
      • Travel limit switches for controlled crane movement
      • Ground anchoring devices for outdoor operation
      • Optional anti-deviation correction system for extra-wide spans
These safety systems improve crane stability, ensure precise traveling control, reduce operational hazards, and enhance the overall reliability of heavy-duty shipyard lifting operations.
