Crane Slew Bering Inspection 1

[BrianBT]

We have a large and complicated Crane assembly. There are few facilities able to pick the structure up even after partial disassembly to carry out a required 5 year inspection of the slew bearing. I appreciate that there are methods or jacking up but I am currently clueless about the practicalities of this

Does anybody know any approved method of inspection such as Grease analysis, UT measurement that would provide a sufficient level of detail for a classification society to be satisfied

Try Lloyds Register in Fenchurch, London. The offer a grease analysis service as a condition monitoring service for approval purposes.

So should the Bearing Vendor.
There is also a method of checking
the displacement by reversing the
moment loads. Ball or Roller Bearing?

Here is a reference to Gerry45's post concerning Lloyd's.

Both these companies offer a bearing inspection service in several different forms.
