Heres a question for everyone. Im installing a new T-base for my crank-up US Tower so that I can use the raising fixture and stop climbing it when its retracted. (getting too old for that) and Ive go
You're asking for engineering analysis of a non-standard scenario. Any advice would be risky. 1.125" bolts in a 2.5" diameter hole leaves a lot of space for fill. It appears to me that you'd want to
Marv, We use the HILTI system at the N2MO station for a new Rohn base plate on an existing reenforced slab Our PE refereed us to ACI 318 Appendix D and CSA A23.3 Annex D for the technical requirement

I like the idea of a device that would get me to the top of the nested tower. Mine is also a tilt over, but there are buildings, a fence, and a guy anchor with guy lines to the big tower that prevent

While I don't have detailed specifications, I know from experience heating drug store sulphur to a liquid and pouring it into such holds provides an extremely strong bond to the the bolts and concret

I asked a PE at work and since the holes are so much bigger than the bolt. ( the holes are 2.5" diameter, the bolts only 1.125") he said the rated strength of the epoxy is only good if the hole is no
the base is designed for 1-1/8 bolts. Sent from my iPad And YES it's cool! _______________________________________________ _______________________________________________ TowerTalk mailing list Tower
Marv, I reached out to our PE and explained your situation. His reply was to suggest that you retain the services of a local PE (stating the obvious and CYA) He did mention that he was involved in a

How about larger anchor bolts with upper six inches or so machined to fit the base holes? Could the base holes be reamed to a larger size? K5GW In a message dated 10/15/2014 12:09:54 A.M. Central Day

I haven't purchased any lately but previously was able to buy it from the local drug store in 1 lb. packages. I don't remember the price but it wasn't much. Once installed, it appeared strong enough
Just trying to help. It seems you have only a few choices, some which may be unpalatable.. 1) use larger bolts to fit the holes and find a way to make them work. (Enlarge the mating holes on the base

That's exactly what I was thinking, Gerald. Marvin's greatest constraint is an oversized hole. I would make a trip to a machine shop with some appropriate sized anchor bolts and and have the upper th

I may have missed it, but one very important factor is how deep are the holes and how deep are they supposed to be? If not deep enough the clearance becomes a lesser problem. As far as threaded bushi
good idea, but I wonder if I can find a 24" long 2" diameter grade 55 bolt and have the top six inches machined? Marv - WA2BFW Sent from my iPad on the iCloud And YES it's cool! _____________________
