Looking at anchoring a piece of equipment that weighs 6,000 lbs and has 8 support legs with 1/4" thick base plates.  What type of Hilti anchor is best for use on a 6" elevated concrete slab supported by 1-1/2" metal deck?

Are you looking at going with an epoxy anchor?  If so, you could use like a Hilti HIT RE-500, or HY-150.  Probably a 1/2" diameter with 4" embedment max (you are limited to 2/3d for embedment)

The Kwik-Bolt 3 Expansion anchor is easy to install and you don't have to wait for epoxy set-up.

I agree with the Hilti Kwik-Bolt III.  Watch your embedment depth at the raised metal deck rib.

Call Hilti.

What are the loads experienced by the Hilti anchor?

is this just for gravity loads, or hanging, etc? Hilti has load charts, etc that will help you pick out what you need.
Be carefull if its a hanging load, some epoxies are not for long term, etc.

I recommend getting your hands on the Concrete and Masonry Fasteners by Simpson.  I've found their catalog a lot easier to use over Hilt's.  In particular, I would recommend using the Titen HD by Simpson.

the loads are gravity only and not hanging, holes in the base plates are 13/16" diameter so a 3/4" diameter anchor would seem appropriate except that Hilti has a minimum base material thickness listed in their catalog.  With the 1-1/2" metal deck the minimum floor slab thickness would be 4-1/2".  Most of the epoxy anchors require more slab thickness so the Kwik Bolt 3 does look like the best option.

Agree with abusementpark. Simpson's catlog is much easier to use than Hilti's and the Titen HD type anchors (essentially large diameter screw anchors ) are gaining acceptance and replacing expansion anchors in our area of the country now that they have gotten the required ICC testing and approvals in regards to ACI Appendix D

Agreed that Hilti website stinks.

We often use the Powers Wedge-Bolt.  This is basically a large diameter tapcon that comes in 3/4" diameters.  We prefer the concrete screws over expansion bolts since they typically have higher connection strengths and work much better in vibration / seismic applications.

So you are not concern with seismic for this equipment anchorage? If you are, go with Hilti-KB-TZ. The KB-III does not have the approved ICC report for concrete use for the new ACI code. Here in California, we always use KB-TZ for concrete, KB-III is strictly a masonry anchor now.

Another option is the Simpson Titen HD anchor. It's a concrete screw anchor so installation is supposed to be easier.

Like other people have mentioned, call Hilti and Simpson and they will tell you all about those.

Hilti has a software program out right now for their anchoring products. Takes some getting used to, but could be worthwhile.

Simpson also has a free anchorage program that is supposedly in accordance with ACI Appendix D.

Einstein, I have to ask, who are you agreeing with?

jrisebo:

Everyone that thinks navigating the Hilti website, and more particularly, finding the load ratings, is a pain.

Oh, ok. I just didnt get that out of this post.
