P Rail Model Crane Rail Overhead Crane Spare Parts P18/ P24 Yb222-63 Standard
Crane rails are designed for carrying heavy loads and are used in a
wide variety of applications. There are seven normal crane rail
models called P18, P24, P38, P43, QU70, QU80, QU100 in China. Rail
weight ranges from 18kg to 88kg per meter. You can find a weight
and measure conversion table on to us if you need.
Each rail application is different and must be engineered to
maximise efficiency and lifespan, therefore the selection of the
correct rail is critical to achieving this end.
