Irwin Quality Through and Through

Irwin Car crane wheels, industrial wheels and sheave wheels are all produced in general accordance with standards for Heat Treatment, Chemistry and Mechanical Requirements as outlined in ASTM A-504, CMAA (70-4.13.2) and AISE (T.R. 6, 1996, 3.7 and 3.7.1) guidelines for industrial grade crane wheels, and produced from the highest grade vacuum-degassed steel.  Typical material grades include AISI C-1045, C-1055, C-1070, 4140 and 4340 steels. All of our crane and industrial wheels are normalized prior to heat treatment, undergo a proprietary hardening process, are immediately quenched, then tempered back to the stable hardness range required by the application or design.

Custom materials and hardness processes are also available for special applications.

Irwin Car crane wheels can be NDE tested upon request or as required, with UT (Ultrasonic) testing per ASTM A-388 and MT (Wet Magnetic Particle) testing per ASTM A-275.

Full QC/QA documenation packages are kept on file for every order we process and are available upon request for your Quality Control records.

Crane Wheel Stocking Programs

If you have specific wheels that you always need or are always using, whether due to having a fleet of identical cranes or poor rails that are prematurely wearing your wheels, Irwin Car is ready to support your operations by working with you to develop a stocking plan that is tailor-made to your needs.  Whether you require gantry wheels, bridge wheels, trolley wheels or sheave wheels (or complete assemblies) on a regular basis, Irwin Car will support you by stocking what you need to keep your business on track with the best “just in time” deliveries possible… helping you eliminate as many emergencies as possible.
