Dear sir/madam,

Many kind of crane rails are available in market. But how to choose the correct rails for the following crane.
Crane maximum weights is 20000kg and safe working load is 50000kg. There are 4 steel wheels which the diameter 2ft, width of wheel 10cm.

The type of rail used for your grantry crane will depend solely on the wheels you have. Are they flat, convex, tapered? What hardness are they? Is the crane gear driven by a track, pulley driven with a cable or is it manual? Call crane pro parts in Houston Texas and ask for a man named John Carney. He works in the crane parts business that I used to work in and he is very knowledgeable and will be able to help you out. Tell him Rick from Ohio sent you
