Crown Tread Wheels
For use on I-Beam, S-Beam or Channel.
We machine our Crown Tread Wheels with a custom radius for better wear than standard industry tapers. All Grey Hub Crown Tread wheels are machined from close grain, porous-free molded gray iron castings. They are hardened and heat-treated through-out (not case-hardened) in an atmospheric furnace, oil quenched to eliminate distortion under high heat temperatures, producing uniform hardness for long, trouble-free service, under heat and other severe conditions.
All assemblies come equipped with a heavy duty jam nut, lock washer and grease fitting.We can machine any in-between sizes not listed here. |
