Overhead Traveling Crane Overload

Overhead Traveling Crane Overload

Overhead Traveling Crane Overload

(OP)
I am looking for guidelines to follow and/or requirements to satisfy in the event of an accidental overload of an OHC hoist.  (I am aware of the ASME Engineered Lift criteria which includes a maximum frequency of 2 such lifts in any 12 month period and required pre-lift inspection, post-lift inspection and record keeping; but have not been able to find anything that applies to an accidental overload.)  The object of my inquiry involves a hypothetical top running crane with a rating over 10 tons and the overload of up to approximately 10% above the documented rating.  I have looked exhaustively for applicable OSHA standards and/or interpretations to no avail.

RE: Overhead Traveling Crane Overload

I did some OSHA and Google searching also.  I didn't come across any OSHA regs requiring testing after an accidental overload.  Even the companies who sell crane overload protection don't list OSHA requirements to push their products.  This leads me to think that there may not be any . . . though it goes against my better judgement.

Next time our crane contractors are PM'ing our OHC I will ask them.

More digging . . . Perhaps this is it:

Then:

1926.550(a)(1)
The employer shall comply with the manufacturer's specifications and limitations applicable to the operation of any and all cranes and derricks. Where manufacturer's specifications are not available, the limitations assigned to the equipment shall be based on the determinations of a qualified engineer competent in this field and such determinations will be appropriately documented and recorded. Attachments used with cranes shall not exceed the capacity, rating, or scope recommended by the manufacturer.


Basically, it appears to boil down to manufacturer's specifications and recommendations.  So check with your crane mfg.
