Product Introduction
QU80 crane steel rail is a heavy flat-bottomed crane rail used on crane tracks and heavy lifting installations. It is supplied to the GB QU series of crane rail (GB/T 3426 system) with a nominal weight of 63.69 kg/m, normally in U71Mn steel and standard lengths of 12 m. QU rails are designed for high wheel loads, concentrated pressure and frequent travel, and are the standard track section for portal cranes, container gantry cranes and industrial crane runways.
| Rail type | Weight (kg/m) | Material | Length (m) |

Other Sizes of the QU Series
| Size | Head width (mm) | Bottom width (mm) | Rail height (mm) | Web thickness (mm) | Weight (kg/m) | Material | Length (m) |
|---|---|---|---|---|---|---|---|
| QU70 | 70 | 120 | 120 | 28 | 52.8 | U71Mn | 12 |
| QU100 | 100 | 150 | 150 | 38 | 88.96 | U71Mn | 12 |

QU80 Rail Material Grade
U71Mn is the commonly used steel grade for QU rails, with U75V available as a higher-strength option. Their key chemical compositions are listed below.
| Mark | C (%) | Si (%) | Mn (%) | P (%) | S (%) | V (%) |
|---|---|---|---|---|---|---|
| U71Mn | 0.65 - 0.77 | 0.15 - 0.35 | 1.0 - 1.5 | < 0.040 | < 0.040 | - |
| U75V | 0.71 - 0.80 | 0.50 - 0.70 | 0.75 - 1.05 | ≤ 0.025 | ≤ 0.025 | 0.04 - 0.12 |
U71Mn rails typically provide a tensile strength of about 880 MPa and above with good wear resistance for heavy crane service.
application of qU80 Rail
