What is a double girder gantry crane?

Double beam gantry crane, also known as double girder gantry crane, is a lifting equipment with a door frame structure, consisting of double main beams, supporting legs, lower crossbeam, large vehicle operating mechanism, lifting trolley, electrical system, etc.

It mainly completes the lifting, transportation, loading and unloading of heavy objects in outdoor fields, freight yards, ports, material yards, and outdoor work areas of factory areas. It is a very commonly used heavy lifting equipment in the logistics and heavy industry fields.

Structural characteristics

1. The double main beam structure has strong bearing capacity, good rigidity, and high stability, suitable for large tonnage, large span, and high-level working conditions.

2. The crane trolley is arranged above the double beam, running smoothly, with reliable lifting, lateral movement, and braking, suitable for high-intensity operations.

3. The door frame support can run directly on the ground track without the need for a factory building or a steel roof, making it suitable for outdoor use.

4. Multiple control modes support cab operation, ground remote control, PLC intelligent control, with flexible, stable, and safe operation.

Main advantages

1.Strong bearing capacity: customizable from tens to hundreds of tons to meet heavy lifting needs.

2.Wide homework scope: customizable span and lifting height, covering a large area of homework.

3.Wide applicability: Suitable for complex environments such as outdoor, open air, and high dust levels.

4.Stable operation: The double beam structure has good torsional and bending resistance, and operates stably.

5.Long service life: With high structural strength and reasonable maintenance, it can be used for a long time.

Application scenarios

Steel market, steel structure processing plants.

Ports, docks, freight yards, logistics parks.

Water conservancy engineering, bridge construction, prefabricated component hoisting.

Mining, metallurgy, building materials, and equipment manufacturing.

Installation and maintenance of large outdoor equipment.

How to choose the right type?

When choosing a double girder gantry crane, the following parameters should be focused on:

1. Rated lifting capacity: such as 10t, 20t, 30t, 50t, 80t, 100t, etc.

2. Span: The effective width between the door legs determines the coverage width of the homework.

3. Elevation: The distance from the ground to the highest point of the hook.

4. Job level: Choose A5, A6, A7, etc. based on the frequency of use.

5. Operating environment: outdoor, windproof, rainproof, anti-corrosion, explosion-proof and other requirements.

6. Control mode: cab/remote control/semi-automatic/intelligent monitoring.

Key maintenance points during use

1.Check the track, brake, wire rope, hook, limit switch and other components before use.

2.Regularly lubricate all transmission components to reduce wear and tear.

3.Overloading, diagonal pulling, and other illegal operations are strictly prohibited.

4.Operators must hold certificates before taking up their posts.

5.Regular maintenance and testing.

Conclusion

Double girder gantry cranes have become an indispensable core equipment in modern heavy industry, logistics, and engineering construction due to their advantages of large load-bearing capacity, good stability, and wide applicability.
