Crane rail is a special kind of rail track providing a running surface for various types of cranes such as gantry cranes, overhead cranes.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.
