Hoisting Attachment Standards 1

[Squalus]

I've been looking for standards, for the California and Ontario jurisdictions, that cover hoisting attachment features on oversize loads (attachment items, connected structural members, et cetera).

We will be hoisting large enclosures onto rooftops, using a crane.

Where can these standards be found?

 

[SwinnyGG]

OSHA 1926.

 

[NRP99]

ASME B30 Series Link and related standards.

SwinnyGG and NRP99, thanks for your replies.

I checked those standards, they cover the lifting equipment and latching techniques; they don't cover anything below the hook.

I'll continue to look.

Have you reviewed ASME BTH-1 "Design of Below The Hook Lifting Devices", which is referenced by B30.20.

The only thing this doesn't cover is the design of your "load" for the forces imposed during lifting.

 

[SwinnyGG]

For below-the-hook devices you need to look at B30.20.

To carry this a bit further the the load also needs to be designed to be lifted. This is usually handled by the responsible structural engineer, often using AISC methods.

It is often convenient to design (or purchase) standard lifting lugs that can be tested and given a rating. example: HALFEN DEHA KKT Spherical head lifting anchor system:

Sometimes lifting and transportation loads control the design rather than in service loads. When cost effective this can result in a structural shipping jig being used to protect the shipped product.
