Hang dynamic weight to concrete ceiling (post #214789)

Hi there,

I work for a small company who provide machines to pharmacies. Thing is, as we add new design to the machine, we need to hang some dynamic weight to the concrete ceiling. What do we need to do the installation? Do we need a civil engineer to do the design? Do we also need some certified guys to do the installation?

Thanks & Regards

Since you do not mention the weight nor the dynamics involved of this product, the only two things needed would be a good liability insurance and probably an engineered drawing showing the anchors and the fasteners.

As far as the installers, they also need a good liability coverage along with the designed fasteners and the brains to install as directed.

This was designed 35kg per anchor, dynamic means a motor makes the product shaking.

Hi there,

     Not knowing more about your specific situation, I would guess you will end up using Unistrut and glue-ed in all thread.  It should be easy enough for the average contractor that knows a little about masonry...   

I second Finefinish's (post #214789, reply #5 of 5)

I second Finefinish's recommendation. Unistrut is a great system and they will engineer the assembly as well as the attachment for you. Then you find a contractor who has done unistrut work. If you are still nervous you have a third party inspector take a look at the finished installation and have them sign off the project.

You at least need someone (post #214789, reply #2 of 5)

You at least need someone with some engineering expertese to run some calculations re the load-bearing abilities of the fasteners involved.  If the load is "dynamic" the fasteners likely need to be able to handle 4-10 times the static weight.
