Canadian Runway crane specs

[barilko]

I have a overhead runway crane which runs on an I-beam the length of the building. It uses a 5 ton hand operated chain fall to lift electric motors out for service.

The I - beam was never given an official rating. It was flagged during our crane inspections.

Can anyone tell me where I could find the canadian structural requirements for this beam, so that I can give it a rating?

For cranes we use the Crane Manufactures Association of America design standard #70 for overhead and gantry cranes single web girders. For maintaince we use NAVFAC P-307

The cranes rating is for the system not just the beam. Try contacting the crane manufacture or the building Engieering Firm for the load ratings and retest.
