Widely Used Professional Manufacturing Serious Design Crail Rail
Product Description
P rail model Crane Rail 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.
