Main girder designs of small steel gantry cranes

For different applications, the main girder of the steel gantry cranes can be designed into

• I-beam is used as the main girder, when the small gantry crane is designed with 2-3 meters span.
• I beam with a welded steel square tube as the main girder, when the steel gantry crane is designed with span length larger than 6 meters.
• The truss beam is usually adopted when the steel gantry crane is designed with larger tonnage and large span. All the material added on the beam is aimed to increase the horizontal rigidity.
• Box girder beam which is similar to the main girder of MH type single girder gantry crane is widely adopted, when the small steel gantry crane is used for load handling with weight around 10 tons and span around 5-7 meters;

I-beam, generally used for steel gantry with 2-3 meters span

Reinforced square steel tube is welded on the I-beam, generally used for steel gantry with a span of about 6 meters
