Selection techniques for steel rails for cranes

Crane rails usually refer to rails specifically designed for cranes (such as cranes, track cranes, etc.). The design of this type of rail is different from conventional railway rails, mainly to meet the special needs of cranes moving on the track. Steel rails for cranes usually need to have the following characteristics:

Due to the fact that cranes often bear large dynamic loads (such as lifting loads), steel rails must have strong compressive and bending resistance to ensure the stability and safety of the crane during operation.

The running track of a crane often experiences frequent friction, so the steel rail material needs to have high wear resistance to reduce wear and extend service life.

The size of steel rails used for cranes may be different from railway rails, usually customized according to the load requirements of the crane track, operating environment, and crane specifications.

The selection of steel rails for cranes should be based on factors such as the actual working environment, operating conditions, and weight of the lifted object. Generally, the static load strength, dynamic load strength, and fatigue strength of the steel rails should meet the requirements. If the lifting of heavy objects or the operation time is too long, it is recommended to choose steel rails with higher static and dynamic load strength.

The selection of steel rails for cranes also needs to consider the condition of the track, such as the contour and flatness of the track. In general, when using "38" or "43" steel rails for cranes, the flatness of the track should be controlled within 5mm, otherwise higher strength steel rails need to be selected.
