Diesel generator vibration mounting

This appears to be a "home brew' mounting fixture and the workmanship quality seems to be lower than my backyard Saturday afternoon projects. A few of the things I noticed are:

• Some of the weldment parts seem to have been cut with a hand held cutting torch or plasma cutter and not cleaned up.
• Welding seems to have produced a lot of black smoke, possibly there was some galvanized metal in the weld?
• You seem to have something like 1/4-20 or M6 size yellow chromate threads coming up from the concrete. In my limited experience I have not seen yellow chromate wedge anchors. I would have expected something like a 3/8" (or similar metric) electro-galvanized thread sticking up from a wedge anchor. Are these just threaded rod sticking out of lead anchors?
• The other two mystery bolts are much larger in diameter and appear to be zinc plated. The mixing of materials seems random.
• There appears to be 1/2" (12mm) fiberglass reinforced shipping tape around the springs. That seems like an odd component in a final installation.
• Your picture and your fixture don't match well at all.

I'm not an expert, but I'll suggest that you have more to be concerned with than just the idea that a bolt might be missing.

I like the way you said "home brew" .

We didnt know how the local workshop man welded and the mounting is not ground dynabolt as per installation guidelines. So their idea to hold the mounting movement during EDG running is by installed stopper plate around of it.

Appreciated for your concerned and respond

How easy is it to get on the phone to the original equipment manufacturer and order the correct part as a direct replacement?

The part is correct but the installation was wrong and they insist the idea of this plate stopper which covered the mounting will be oke. There are no science calculation of this stopper plate. I have contact manufacturer and not recommended to start with current installation due to safety reason. Below is the correct installation of the mounting, just for comparison.

Thank you for respond

I can see why they installed it that way, there was no provision to set an anchor after the machine is in place, either poor planning or layout skills were lacking. While unconventional, that is certainly not 1/4" hardware for the anchors, and the shear strength appears more than adequate for possible lateral forces it would see. Maybe get a local professional engineer and pay $800-$1000 to get an opinion, since we don't know your earthquake zone, which the only concern I would have.

Also, there are a couple of bolts threaded into welded nuts, diagonally placed, with no function that I can see, so there is more to this install than we can see from the pictures you thoughtfully provided.

Your example photo bears little resemblance to your actual equipment, so maybe have those people send a photo of a generator mounted on concrete. An 11 ton generator mounted on steel plate would be a highly engineered installation, on concrete, not so much.
