Product Description
QU80 crane rails are mainly used in the crane industry, such as gantry cranes. In addition, they can also be used for large-scale projects and dock hoisting containers.
Gnee’s QU80 rail length: standard length is 12 meters, other lengths are 9/9.5/10/10.5/11/11.5/12.5 meters, and short rails of 6~8.9 meters are also acceptable.
Gnee Rails provides a full set of accessories for the rail system, including rail clamps with rubber noses and weldable base clamps, elastomer rail pads, base bottom plates, rail connection fishplates, bolts and nuts for fixing clamps, and leveling bolts, etc.
As a well-known domestic QU80 rail supplier, we arrange a large amount of QU80 rail inventory all year round, and can provide QU80 rail cutting and stamping processing services.
In addition to QU80 rails, we can also provide rails of various specifications, including light rails, heavy rails, crane rails (such as QU70 crane rails, QU100 crane rails and QU120 crane rails), etc. We also provide fasteners that match the rails, such as rail clips, bolts, rail spikes, etc.
What materials Are Used For Gnee QU80 Rails?
| Comparison Dimension | U71Mn Rail | U75V Rail |
| Tensile Strength | 880 MPa | 980 MPa |
| Hardness (HB) | 260-300 | 280-320 (heat-treatable to 330+) |
| Main Chemical Composition | Carbon (0.65%–0.77%), Manganese (1.00%–1.40%), Low Silicon (0.15%–0.35%) | Carbon (0.70%–0.80%), Manganese (0.75%–1.05%), High Silicon (0.50%–0.70%), Vanadium (0.04%–0.12%) |
| Core Advantages | High toughness, excellent weldability, strong impact resistance, lower cost | High strength, superior wear resistance, long service life, suitable for heat treatment |
| Application Scenarios | Frequent welding sections, high-impact areas, passenger lines (light axle load) | Heavy load/small curve radius areas, high-wear sections, metro main lines |
| Weldability | Low silicon content reduces welding defects, suitable for complex welding needs | Requires optimized welding processes (e.g., induction heat treatment), modern technology has improved this |
| Fatigue Resistance | Low sulfur and phosphorus content (≤0.03%), high purity, resistant to fatigue cracks | High silicon and vanadium refine the microstructure, wear-resistant but requires welding pretreatment |
Features of QU80 Rails From Gnee Crane Rail Supplier
- No brittle cracking in extreme cold: At -40℃, it can withstand 40% more impact force than ordinary rails, making it safer to operate in polar ports and northern mines.
- No deformation at high temperature: In 500℃ heat radiation, the strength retention rate exceeds that of ordinary rails by 14%, and the steel plant equipment runs stably with less maintenance.
- Durable and cost-saving: Laser reinforcement technology doubles the fatigue resistance, extends the rail replacement cycle, and reduces the cost of use by half.
Application
Gnee’s QU80 rail is suitable for the following scenarios:
Workshops, ports or docks
- QU80 rail is suitable for workshops or docks with frequent lifting operations such as the running track of large cranes and gantry cranes in factories, and can carry 50-100 tons of heavy equipment to move;
Logistics and transportation hub
- Our crane rail can be used for the lifting track system of container terminals and railway freight yards to meet the needs of high-intensity loading and unloading, reduce track wear and maintenance frequency, and improve logistics efficiency.
Railway transportation maintenance
- In the maintenance section of subways or railways, it is used as a temporary track;
Heavy machinery track at construction sites
- Provide temporary track support for equipment such as tower cranes and mobile concrete pump trucks, adapt to the complex terrain of the construction site, and can be quickly installed through modular accessories;
Special environments
- Due to its excellent corrosion resistance and anti-corrosion treatment, our QU80 track rail also performs well in humid ports, open-air environments with high and low temperature differences, or mining areas with a lot of dust, which can reduce replacement costs;
FAQ
The following are frequently asked questions by customers. If you have other questions, please feel free to contact us.
What does the QU80 track model mean?
“QU” stands for crane-specific rails (QU series);
“80” means the rail surface width is 80 mm, suitable for medium and high load scenarios.
How to choose the matching fasteners for QU80 tracks?
Recommended fasteners: Rail clip IV or V-type fasteners, suitable for concrete sleepers, provide high buckle pressure and elasticity.
Special needs:
- Small radius curve sections: It is recommended to match with insulating gauge blocks and shock-absorbing pads to improve stability.
- Heavy load scenarios: Choose spring clip V-type fasteners with embedded casing + spiral spikes to enhance the ability to resist lateral forces
How to choose QU80 and other track models (such as QU70, QU100)?
- QU70: light load, low speed scenario, low cost;
- QU80: medium-sized equipment (such as port cranes), high cost performance;
- QU100: heavy load, high-speed railway or large metallurgical equipment, stronger load-bearing but higher cost;
Do you support customized accessories?
Gnee can customize rail clamps, nylon sleeves, elastic rail clips, bolts, etc., and the track beam parameters and fastener drawings should be provided.
