Overhead crane rail also can be called crane track, steel rail track, etc. It is a metal groove or ridge that holds, guides, and reduces friction for a moving device and a steel-striped line used for a running trolley. The theoretical weight of China\'s standard crane track increased from 52.8kg/m to 118.1kg/m. 
  
 
  Crane rails provide a continuous, smooth, and low-resistance rolling surface for the crane wheels. It is employed to guide the wheels of the crane, bear the pressure of the wheel, and transmit it to the sleeper and ground.
