The double girder gantry crane, also called a double beam gantry crane, is one of the most commonly used types of heavy-duty gantry cranes. It is specifically designed for handling large and heavy loads, making it an ideal solution for industrial, construction, and logistics applications. Unlike single girder models, the double girder structure offers higher lifting capacity, greater stability, and a wider span, which makes it suitable for more demanding lifting operations.
Structurally, the double girder gantry crane consists of several key components, including the main beams, end beams, supporting legs, lower beams, trolley running track, operator’s cab, hoist trolley, crane traveling mechanism, and advanced electric control system. These parts work together to ensure smooth, safe, and efficient lifting. The robust design allows the crane to operate on ground rails, either supported at both ends or at one end, providing flexibility for different working conditions.
Applications
The double girder gantry crane is a heavy-duty lifting solution with strong load capacity, simple structure, and convenient operation. It is widely used in different industries and scenarios, including:
Manufacturing Industry: In automobile, shipbuilding, wind power, and machinery manufacturing, the double girder gantry crane is used for assembling, disassembling, and transporting large equipment. It also facilitates the handling of raw materials and finished products, ensuring smooth production processes.
♦Construction Sector: On construction sites, this crane is widely applied for lifting and moving heavy building materials. Its ability to handle large structural components improves installation efficiency, supports safe construction work, and speeds up project completion.
♦Logistics and Warehousing: Heavy duty gantry cranes are essential in logistics centers and warehouses for loading, unloading, and container stacking. Their strong capacity and wide operational range help achieve faster cargo movement and better warehouse management.
♦Ports and Terminals: At container yards and bulk cargo terminals, these cranes are critical for handling heavy containers and bulk goods. Their reliable performance meets the demanding needs of port operations, improving efficiency in loading and unloading.
♦Railway Freight Stations: In railway transport, heavy duty gantry cranes are used for loading and unloading steel, wood, machinery, and other bulky cargo. They are also applied in railway construction projects for lifting tracks, bridge components, and other large building materials.
♦Outdoor Storage and Material Yards: Thanks to their high lifting capacity and wide span, double girder gantry cranes are suitable for open-air warehouses, stockyards, and heavy-duty workshops, offering efficient solutions for large-scale cargo handling.
With its reliable performance, strong load-bearing capacity, and long service life, the double girder gantry crane is widely applied in ports, shipyards, factories, warehouses, and construction sites. It not only improves productivity but also ensures safety and efficiency in heavy-duty material handling.
Main Types and Configurations of Double Girder Gantry Cranes
Double girder gantry cranes are one of the most widely used types of overhead lifting equipment. Characterized by two robust girders supported by vertical legs, these cranes travel on rails or wheels and provide excellent strength, stability, and lifting capacity. They are ideal for handling heavy loads across a wide working area and are commonly used in shipyards, factories, logistics hubs, and construction sites. Depending on the working environment, there are several main types and configurations of double girder gantry cranes.
♦Full Gantry Crane – The full gantry crane runs on rails laid on the ground, with both legs traveling on the rails. This design is especially suitable for outdoor applications such as ports, shipyards, steel yards, and construction sites, where large-scale lifting and movement of heavy materials are required.
♦Semi-Gantry Crane – The semi-gantry crane has one end supported by a leg traveling on a ground rail, while the other end is supported by an existing building structure or a fixed mast. This design helps save space and is suitable for indoor workshops or sites with limited working areas. Both single girder semi-gantry and double girder semi-gantry configurations are available depending on load requirements.
♦Rail Mounted Gantry (RMG) Cranes – Rail mounted gantry cranes are widely used in container terminals and intermodal yards. Operating on fixed ground rails, they efficiently load and unload containers from ships, trucks, and trains, offering precision and high productivity in container handling.
♦Rubber Tyred Gantry (RTG) Cranes – Equipped with durable rubber tires instead of fixed rails, RTG cranes offer maximum flexibility and mobility. They are frequently used in container yards, warehouses, and manufacturing facilities, where the ability to move independently across different areas is crucial.
