Equipment Installation
Equipment Installation
(OP)
I am working at a facility where they are installing two post automotive hoists (as in a garage). The concrete floor isn't level, and they are trying to level the base plates of the two posts for each hoist. They are cutting 1" thick steel "shim plates", and using those to try and level the posts. I believe this is a bad idea. My concern is that the plates will shift or move, and might put shear forces on the anchor bolts.
I would rather they use a jack bolts to level and then grout around the base.
Any opinions?

If they are using 1" steel shims, how rough is the floor? It sounds like it is "rough as a corn cob", a tripping hazard? You might consider cutting out the floor section under the hoist and repouring it. The hoist are the pitless type?

I hadn't even thought about the fact that the cost would probably be comparable, especially since they have had to lift it a couple times to scribe a template to work from.
I'm going to try one more time to get them to consider leveling and grout in place. I think that they consider it overkill.
