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.

Sections marked CR (104 through 175 lb/yd) are crane-rail sections covered by ASTM A759; the lighter ASCE sections are tee rails. The face and float values above are the catalog recommendations as published, with float allowances that vary by rail size. The face widths run wider than the head width plus 1-1/2 inch minimum (3/4 inch float per side on new rail) described in Matching Crane Wheel Tread Width to Rail Head Width; confirm the face width against the actual rail section and the crane's float requirement before finalizing a drawing.
Ready to Specify Your Crane Wheels?
UTEC Industrial machines precision crane wheels and sheaves from forged alloy steel stock for heavy industry across the US, with in-house induction hardening and chemistry testing on every heat. Nearly all wheels are produced to customer drawings or reverse-engineered from worn samples. Send UTEC the application — load, speed, and duty cycle — and get the right wheel specified.
