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.

When selecting crane rails, applicable standards and guidelines should be referenced, with consideration given to factors such as load capacity, crane type, and operating conditions to ensure appropriate rail sizing. Different crane rail dimensions suit distinct engineering requirements and application scenarios.
Smaller rail sections are suitable for light-duty cranes and light-load applications, while larger sections accommodate heavy-duty cranes and large-load applications. Consequently, the following factors must be evaluated when determining crane rail dimensions: the crane's working load and load range; the movement range within the operational area; the crane's operating speed and precision requirements.
