Shipyard Gantry Crane Manufacturer | Heavy Duty Shipbuilding Crane

What Is a Shipyard Gantry Crane?

A Shipyard Gantry Crane, also known as a shipbuilding gantry crane, marine gantry crane, or shipyard portal crane, is a heavy-duty lifting machine designed for ship construction, ship section assembly, and large marine equipment handling. It is mainly installed in shipyards, dry docks, and shipbuilding areas to lift, transport, and position large hull blocks and heavy components.

The crane is built with a high-strength gantry structure, large-span design, and a precise control system to handle complex shipbuilding operations. With lifting capacities commonly ranging from 50 tons to over 1000 tons, it is used for hull block turnover, ship section alignment, assembly and installation of large equipment.

Designed for harsh marine environments, the crane features rigid steel structures, corrosion-resistant treatment, and adjustable working parameters. The span, lifting height, and duty class can be customized according to shipyard layout, vessel size, and production requirements, with typical duty ratings from A5 to A8 for different operating conditions.

The shipyard gantry crane is built with a large steel structure, lifting units, traveling system, and control equipment. The components work together to handle hull blocks, marine equipment, and other heavy loads in shipyard operations.

Shipyard Gantry Crane parts

Portal Steel Structure: Main load-bearing frame composed of the girder, rigid legs, and flexible legs, supporting the crane structure and lifting loads.

Main Girder: Double box girder structure that supports trolley movement and withstands lifting loads.

Rigid Leg: Fixed support connected to the girder, providing structural stability during operation.

Flexible Leg: Hinged support that absorbs structural deformation caused by temperature changes and foundation movement.

Upper Trolley: Equipped with two lifting hooks for heavy hull block lifting and turning operations.

Lower Trolley: Works with the upper trolley for lifting, positioning, and hull block assembly.

Traveling Mechanism: Includes motors, reducers, and wheel sets to move the crane along rails.

Hoisting Mechanism: Composed of drums, wire ropes, and pulleys for lifting and lowering heavy loads.

Electrical Control System: PLC and variable frequency control system for speed regulation and operation monitoring.

Safety Devices: Includes overload protection, wind protection, and anti-collision systems.

Operator Cabin: Provides crane operation controls and monitoring equipment for precise handling.

Maintenance System: Includes elevators and service platforms for equipment inspection and maintenance.

The combination of these components allows the crane to perform heavy lifting, hull assembly, and equipment installation tasks in shipyards, docks, and marine construction areas.

Принцип работы

The shipyard gantry crane performs lifting operations through coordinated movement of the crane, trolleys, and hoisting system. The process includes positioning, lifting, turning, and accurate placement of ship sections.

1. Crane Positioning — The traveling mechanism moves the crane along the rails to the required lifting area. A variable frequency drive controls the travel speed and positioning accuracy.

2. Trolley Positioning — The upper and lower trolleys move along different tracks on the main girder. They can operate independently or together according to the lifting requirements.

3. Lifting and Transport — The hoisting system uses drums, wire ropes, and pulley blocks to lift loads. Variable speed control allows smooth lifting and precise positioning, with inching speeds of 0.1–0.5 m/min for assembly work.

4. Air Turning and Assembly — The upper and lower trolleys work together to lift and turn hull sections. Different hook movements allow 180° air turning and accurate alignment during hull assembly.

5. Placement and Release — The crane lowers the load to the installation position through low-speed control. After the section is secured, the hooks are released to complete the lifting cycle.

Through coordinated control of each mechanism, the shipyard gantry crane completes heavy lifting, hull section handling, and precision assembly operations in shipbuilding projects.

Часто задаваемые вопросы

Поддерживает ли данный промышленный портовый кран удаленную диагностику?: Yes. Our equipment can be equipped with an intelligent monitoring system, achieving real-time status monitoring and fault warning through remote data transmission, ensuring the safety and continuity of shipyard operations while shortening maintenance downtime.

Подходит ли этот козловой кран как для автомобильных заводов, так и для судостроительных верфей?: Да, он предназначен для грузоподъемных работ в автомобильной промышленности и на верфях.

What is the difference between a Ship-to-Shore crane and a quayside container crane?: They refer to the same machine type. “Ship-to-Shore crane” (STS crane) is the international industry term used in port planning and procurement. “Quayside container crane” is the common Chinese technical designation. Both describe the portal crane installed at the apron edge of a container terminal to transfer containers between vessels and the dock. Weihua uses both terms interchangeably in its product documentation.

Какова грузоподъемность портового крана?: Краны STS обычно предлагают грузоподъемность при одном подъеме от 40 до 65 тонн, а при двойном подъеме — до 80 тонн, что подходит для послепанамских и ультра-послепанамских контейнеровозов.

Какова максимальная высота подъема портового перегружателя?: STS-краны рассчитаны с высотой подъема 40-55 метров над рельсами и 15-20 метров под рельсами, что обеспечивает эффективную обработку судов с высокой палубой и контейнеров глубокой укладки.
