QU120 Crane Rail
GB crane rails are specifically engineered for crane applications, ensuring safe and efficient operation in various industrial settings. These rails are manufactured to meet strict GB standards, guaranteeing high-quality performance.
QU120 Crane Rail | Ultra-Heavy Duty Port Crane Track
QU120 crane rail is the largest and heaviest profile in the QU series of crane rails, with a theoretical weight of 118.1 kg/m . It is made of high carbon steel U71Mn with tensile strength of ≥880 MPa, excellent wear and fatigue resistance, and is suitable for frequently impacted operating scenarios.Manufactured to Chinese standard YB/T5055-2014, this rail is specifically designed for the most demanding ultra-heavy-duty applications.

GNEE RAIL supply premium QU120 rails manufactured from high-carbon, wear-resistant steel to ensure structural integrity and maximum service life under continuous heavy wheel loads.
What are the differences between QU120 and DIN 536 A120 Crane Rail?
QU120 and DIN 536 A120 are both high-strength 120mm head-width crane rails used for heavy-duty, high-frequency, and industrial applications. QU120 is a Chinese standard (YB/T5055-2014) rail, while A120 follows European DIN 536 P1:1991 standards. A120 offers a wider, flatter profile (220mm base), while QU120 is taller (170mm vs 105mm) and heavier.
| Parameter | QU120 (GB YB/T5055) | A120 (DIN536) | Difference / Compatibility |
|---|---|---|---|
| Standard | Chinese YB/T5055-2014 | German DIN536 | Different standards - not interchangeable without verification |
| Head Width | 120mm (129mm at corners) | 120mm | Similar nominal head width - good for wheel compatibility |
| Rail Height | 170mm | 105mm | Major difference - QU120 is 65mm taller |
| Bottom Width | 170mm | 220mm | Major difference - A120 has much wider base |
| Web Thickness | 44mm | 72mm | Major difference - A120 has much thicker web |
| Weight | 118.1 kg/m | 100 kg/m | QU120 is 18% heavier |
| Material | U71Mn | U71Mn | Similar material grade |
| Typical Application | Shipyard gantries, STS cranes, ultra-heavy industrial | Ports, shipyards, factories | Both for heavy-duty, but different design philosophies |
Heavy-Duty Fastening System & Rail Processing
Securing a crane rail requires specialized, heavy-duty fastening systems to absorb massive lateral thrust from crane operations. GNEE RAIL supply fully compatible accessories:
- Adjustable Crane Rail Clips: Heavy-duty welded base clips with vulcanized rubber noses to withstand high side loads.
- Continuous Rubber Pads: 7mm or 9mm steel-reinforced rubber pads to distribute weight evenly to the concrete/steel girder and reduce vibration.
Value-Added Processing:
- 45° Miter Cutting: We provide precision 45-degree angled cuts for expansion joints, which are heavily required in long-distance port tracks.
- Hole Drilling: Custom drilling for bolted fishplate joints.
Products Description
Q：What are the different types of rails?
Railway rails are primarily classified by their cross-sectional shape into Flat-Bottomed (Vignoles) (most common, ~90% usage), Bull-Headed, and Double-Headed rails. Specialized types include grooved rails for trams, check/guard rails for safety at curves, and continuously welded rails (CWR) for high-speed, smooth travel.
Q：What is the difference between crane rail and train rail?
Crane rails are specialized, heavy-duty steel profiles designed with wider heads, thicker webs, and higher-grade steel to support intense, concentrated loads and high lateral forces in industrial, short-distance applications. Conversely, train rails (railway rails) are designed for long-distance, high-speed, distributed loads with higher profiles (like I-sections) focusing on longitudinal stability and bending resistance.
Q：What is the standard crane rail?
Standard crane rails are specialized steel profiles designed to support heavy-duty lifting equipment, categorized by weight (light <30kg/m, heavy >30kg/m) and regional standards, such as DIN 536 (A-series), ASCE (American), JIS (Japanese), or Chinese QU series. Common standards include A100/A120, QU70/QU80, and ASCE 60-85, typically made of high-carbon steel (0.40%-0.70%) with 260-380 HB hardness.
Q：What is the HSN code for crane rail?
The primary HSN code for crane rails (iron or steel) is 730210 (specifically 73021090 for "other" rails), which covers railway or tramway track construction materials. Depending on the specific application or if they are considered parts of lifting machinery, they may also fall under codes 843149 (parts for cranes) or 8426.
