Q Straint anchor removal

Greetings,
I'm working on removing the Q Straint anchor point bolts from my bus floor. The bolts are frozen. Does this mean I have to grind off the bolts underneath? Suggestions please!

There's a good thread on this subject, with several methods discussed. Personally, I put a diamond wheel on my angle grinder, and ran right down the middle of the track. You can then pry up each side, and grind off the bolt heads easily

Like Dave said. Carbide cutoff wheel on an angle grinder wear gloves and safety glasses.

Good suggestionss

Thanks for these ideas. Since I have just attachment points not rails, I'll try removing the top part of the device with my current cut of wheel first to see if it works before purchasing a diamond one. I'll post a picture soon that shows what they look like.

And you can just cut the bolt off from underneath if it’s accessible. Wear eye protection and gloves!

A nut splitter might work. I had the same system and rusted bolts issue. I was able to grind off some, sawzall a couple from below. One was obstructed by a toolbox from below so I ended up breaking out as much plywood as I could and using the sawzall between the anchor and sheetmetal floor, there was about 1/4" to work with.

Qstraint removal update

The other day I worked on the removal of two attachment points. I made images of the process. The one accessable from below was easy with the angle grinder. The one from above with just the grinder, not so much. I tried to grind a line across, hoping to break the plate in two to remove and get to the brolt. I managed to do both at the same time, meaning Hitting the bolt head while cutting the plate.

More on Qstraint

So, A new set of anchors. I changed tactics. This time I grinded from the bolt side to remove the anchor while leaving the bolt intact. Then, I grinded off the bolt head.
