Truss Girder Portal Gantry Cranes are a variation from the typical beam or box girder that becomes economical when long crane spans are required. Additionally, many truss girders allow the hoist to be located "up into" truss thereby offering much better hook height than a single beam or box girder crane. Also, truss girder cranes are typically more economical than long span beam or box girder cranes. Truss girder cranes offer almost limitless span - but capacity is often limited with longer spans. Truss girders are also used on outdoor long span cranes in order to reduce effects of wind on the crane drive system.

Gantry portal crane can be applied to both single girder and double girder format. It is ideal for outdoor applications where lifting devices can be applied without the cost of supporting steelwork. Indoor applications are also available where with a low ceiling and overhead cranes are not suitable. Typical occasions of goliath gantry crane include steel stock yards, loading areas, the concrete industry, ship building, and workshops.

About Us

FAQ

• Q. What's the information should I provide when inquiry?
  

  More details or drawings, better. A: Lift capacity B: Concrete Beam Span C: Turning Radius D: power source or other specials you give us will be more appreciated.

• Q. Can this type work in hazardous environment?

• A:Sure! We can customize for you, acid proof or explosion proof, no problem for that.

  
  

• Q. How can we install the crane?

• A:Our senior engineer can be your side to do the installation guide service and training. Moreover, our best sales can visit your country.

  
  

• Q. Notes:This highway construction crane can be rail type and step type. The rail type crane is mainly used for lifting of beams with length not more than 30m. While the step type crane need no rails, which has no pressure and damage to the highway beam/bridge because the legs can be landed on the supports.
