- ASME B30.9,
there's an update.
Are you still compliant?
If you wanna find out, then stick around.
In this video, I'll break down what's new
in the ASME B30.9-2021 update.
(upbeat music)
My name is Ben and this is the lifting and rigging channel.
The American society of mechanical engineers is
a professional association and leading international
developer of codes and standards
when it comes to the practice of mechanical engineering.
Their standards work to enhance safety
and offer best practices and regulations
within specific industries.
And their standards are often enforced by OSHA.
ASME B 30.9 Slings is specific to load handling
lifting slings used to connect
and support a heavy load.
Due to technological advances,
new data, and changing environmental and industry needs
ASME revises and amends their existing standards
and releases a new addition every couple of years.
Today I'll break down the important changes
in ASME B30.9-2021 Slings,
the new edition compared to the 2018 edition.
So you can be sure you're still complying
with ASME B 30.9 standards.
So let's get into it.
In the lifting and rigging world
ASME B30.9 is one of the most commonly referenced standards
that applies to the fabrication, attachment,
use, inspection, testing, and maintenance
of slings used for load handling purposes.
It applies to wire rope slings, alloy chain slings,
synthetic rope slings, metal mesh slings,
synthetic web slings, and synthetic round slings.
So what's new?
The 2021 edition of ASME B30.9
contains updates including the new non-mandatory appendix A
on sling protection,
a new definition for alloy chain endless slings,
and updates of the sections
addressing proof test requirements,
rated load and operating practices.
Let's dive into some of the more important changes.
ASME B30.9-2021 has added a new definition
for endless sling alloy chain.
They define this as a chain sling made from one
continuous length of alloy chain
with both ends joined by a welded link
or mechanical coupling link.
They've added in a new diagram to illustrate
an endless sling straight line hitch,
and they have revised the fabrication section to allow
for mechanical coupling links within an endless sling.
For fabrication of endless slings, only welded
or mechanical coupling links suitable for the purpose
and recommended by the link manufacturer,
or a qualified person shall be used.
ASME have added a best practices section concerning
endless slings as well.
If a mechanical coupling link is used to join chain links
in an endless sling, the link should not bear directly
against the load, a hook or other fitting.
ASME B30.9-2021
also now allows for the repair of an alloy chain sling
with a mechanical coupling link,
but only if the mechanical coupling link
is replacing an original mechanical coupling link
that was already approved
by the manufacturer or a qualified person.
ASME has added a new factor that determines the rated load
of a wire rope sling, synthetic rope sling,
synthetic webbing sling, polyester round sling,
and a high performance round sling.
Now when determining the rated load of these slings,
on top of the previous factors,
the connection hardware shape and size must be considered.
ASME B 30.9, 2021
now includes a non-mandatory appendix
regarding sling protection.
This entire appendix is new
and includes precautions, considerations, guidance
and diagrams concerning sling protection.
I highly recommend reading it thoroughly.
I'll do my best to quickly sum up
some of the important information.
Slings under tension can cause a load failure
when they contact surfaces,
corners and edges.
A sling user should be trained to understand
and recognize the damage potential
and what steps should be taken to avoid sling damage.
If the rigging requires a sling to directly
contact the load based on the hitch method,
care should be taken to identify potential
for sling damage.
Steel slings should be protected,
and synthetic slings shall be protected.
Slings can be damaged by rough, ribbed or uneven surfaces.
The bearing pressure at the sling to load contact point
can result in significant deformation and shearing
in both synthetic and steel slings.
Even if an edge does not look or feel sharp,
a sling can be cut with only moderate pressure,
and this could happen at any point during the lift.
ASME B 30.9 2021 non-mandatory appendix A
goes into great detail respecting guidance
on how you can avoid these different failures
and how you can protect your slings.

I hope this video gave you the information you need to keep
up to date with the new ASME B 30.9, 2021 standard.
We know that what's most important to you,
is keeping everyone safe and staying OSHA compliant.
The new standard takes effect December 22nd, 2022.
