Complete Rail Classification Guide: Weight, Strength, and Applications

1. By Weight: From Light Rail to Heavy Rail The most common way to classify rails is by weight, which directly reflects the cross-sectional size and load-bearing capacity: · Heavy rail series: 43 kg/m and above (e.g., 43 rail, 50 rail, 60 rail, 75 rail) · Light rail series: Below 43 kg/m (e.g., 24 r

How to Detect Damage in Crane Wheels

The crane wheel is a component that is relatively prone to damage. Based on its operating characteristics, the wheel tread must have high hardness and a certain depth of hardened layer and transition zone (depth >10mm, hardness HRC 40–48) to enhance load-bearing capacity, wear resistance, and con

How Steam Locomotives Work

I. Drive Structure of Steam LocomotivesEach driving wheel of a steam locomotive is connected by coupling rods. The connection point on each wheel is not at the axle center, and combined with the weight of the rod itself, this causes the center of gravity of each wheel to shift.When the locomotive ru
