Crane Wheel Technical Data Sheets: Dimensional Specifications & Load Ratings
This technical reference provides dimensional specifications for UTEC Industrial's crane wheels, maximum bridge and trolley wheel loading tables by CMAA service class, and wheel tread contour recommendations for various rail sizes. UTEC Industrial manufactures precision-machined alloy steel crane wheels, sheaves, and industrial components from AISI 4140, 4340, and 8620 billets in the Pacific Northwest, with in-house induction hardening, CNC machining, and chemistry testing on every heat. These data sheets serve as a specification resource for engineers, designers, and procurement specialists selecting crane wheels for industrial applications.
