How to Select the Right QU Crane Rail

Oct 09, 2025 Leave a message

Crane rail is a special kind of rail track providing a running surface for various types of cranes such as gantry cranes, overhead cranes. QU crane rails are mainly applied in big projects including wharf, ports and yards. The sizes of crane rail needed are decided by the wheel of cranes. For the safe operation of cranes, there is a certain distance between the rail surface and crane wheel rim. Therefore, it doesn't mean the larger width of the rail head is better. Suitable crane rail size is recommended for clients to fit the specific model of crane.

How to Select the Right QU Crane Rail

 

Assess Load Requirements


Evaluate crane type and lifting capacity to match the appropriate rail size-e.g., QU120 is ideal for cranes handling over 100 tons of load regularly.

 

Rail Type SIZE(mm) theoretical weight
height bottom width head width waist depth
Crane rail QU70 120 120 70 28 52.8
QU80 130 130 80 32 63.69
QU100 150 150 100 38 88.96
QU120 170 170 120 44 118.1

Consider Environmental Needs


Select U71Mn steel grade when operating in harsh environments such as coastal ports or impact-prone zones requiring high strength and corrosion resistance.

 

Steel Grade C(%) Si Mn Cr V P S Tensile Strength (Rm/MPa)
U71Mn 0.65~0.76 0.15~0.58 0.70~1.40 ≤0.035 ≤0.030 ≥880
