QU100 GB Standard Crane Rail

The QU100 GB Standard Crane Rail is engineered specifically for heavy-load operations, strictly complying with the Chinese GB/T 3426 (or YB/T 5055-2014) standard. Featuring a widened rail head and a thickened web, it provides superior stability and wear resistance under extreme point loads. It is widely specified for heavy-duty gantry cranes, port terminal infrastructure, shipyard slipways, and automated warehouse overhead cranes.

If you have special requirements for length or higher strength materials, please contact us for special custom production.

We supply prime quality QU100 rails with exact dimensional tolerances and certified steel grades to ensure the continuous, safe operation of your heavy lifting equipment.

U71Mn Steel Chemical Compositions:

QU100 crane rails (100mm head width) are heavy-duty rails, often made of U71Mn steel, designed for high-load applications typically handling 100+ ton cranes or 150-ton cranes with 250kN wheel pressure. They are primarily used in port gantry cranes, steel mill overhead cranes, and heavy industrial, mining, or metallurgical environments requiring high strength, wear resistance, and stability.

• Overhead Bridge Cranes:Factory workshops, warehouses, and manufacturing facilities where cranes move along elevated runways.

 

• Gantry Cranes:Outdoor yards, storage areas, and construction sites where cranes run on ground-level tracks.

 

• Port Equipment:Container handling cranes, ship-to-shore cranes, and yard cranes at marine terminals.

 

• Steel Mills:Heavy overhead cranes handling molten metal, coils, and raw materials.

 

• Automated Warehouses:Stacker cranes and automated retrieval systems.

QU and DIN536 are both heavy-duty crane rails, with QU (Chinese standard) often favored for higher vertical load capacity and cost-efficiency in Asia/Africa, featuring a taller profile. DIN536 (European "A" type) is known for wider bases, providing superior stability against lateral forces and, better, more precise, and widely used for European projects.

Key Differences:

• QU rails (QU70, QU80, QU100, QU120) are Chinese standards frequently used in Asian/African markets. Features a higher profile, smaller head width relative to height, and thicker web, designed to handle high vertical loads and reduce stress.

• DIN536 (A45-A150) is the German standard commonly used in Europe and international projects.Characterized by a wider base and lower center of gravity, which provides excellent lateral stability and better load distribution.

Can QU Series Crane Rails and DIN 536 Crane Rails be used interchangeably?

QU Series (Chinese standard) and DIN 536 (European standard) crane rails are not directly interchangeable. While they are both used for heavy-duty gantry and overhead cranes, they have different rail head widths, heights, and base widths, meaning fastening systems and wheel profiles often need to be specifically matched to the rail. Direct replacement will cause poor matching with crane wheels, rail clips, tie plates and other accessories, which will affect operation safety and stability.

Q: Can you bend the QU100 rail for curved tracks?

A: Yes. Although QU100 is highly rigid, we offer in-house professional cold-bending services. We can bend the rails to your specified radius for rotary cranes or circular track applications. Please send us your radius drawings.

Q: What is the difference between QU100 and standard railway tracks?

A: QU100 is designed for heavy, slow-moving point loads (like a gantry crane). It has a wider flat base and a thicker web. Standard railway rails (like 60kg rails) are designed for faster-moving trains with dynamic impacts and have a different cross-sectional profile.

Q: Do you provide matching fasteners and accessories?

A: Yes. We supply complete rail systems including rail clips, fish plates, bolts, and rail pads designed for QU100 profile.

Q: What documentation do you provide with shipments?

A: We provide mill test certificates showing chemical composition and mechanical properties, plus compliance certification to YB/T5055-2014.
