Earth Anchors

Hi,
Looking for these (photo below) typically used by utilities for bracing utility poles. Can anyone suggest how to get these in Alberta, Canada?
The obvious suppliers have stopped carrying them (Anixter, EECOL, Westburne, Graybar, Acklands Grainger, etc.) Others have gone out of business.
Maybe I'm missing something else that's obvious. Any ideas?

In case it needs to be said, I'm looking for any earth anchor that can offer more than 4000 pounds when installed in sandy soil, so if you know of an alternative to Hubbell, please speak up. The catalog page is just an example of what worked before.

Check out "Grain Bin Anchors" Spar. You should be able to find a good assortment in Alberta. UFA may have something suitable available if not on the shelf.

Maybe duckbill anchors could work for you instead of the screw in ones. If one isn't enough, you can drive is a cluster so the cables all meet at a common point.
 
Thanks,
Those are a good start. I don't have much optimism about getting an order from a US supplier across the border any time soon, however.
I also have some farm-store anchors which are much smaller than these and in my soil probably won't hold 1000 pounds, let alone 4k.
Duckbills are also on the small side. Manta Rays are much bigger. Maybe.

I'd still prefer screw in anchors because I'm having a contractor come to put in screw piles for the base of the tower (this is a wind turbine, for those who haven't guessed). The equipment to drive the piles can also drive the screw anchors, but these contractors don't actually have any of the screw anchors. A problem I hadn't properly anticipated.

FYI, the guy-wire pre-load tension is going to be up to 2000 pounds.
 
I was thinking about screw piles. Will the budget handle screw piles for anchors?

Umm probably not.
50$ VS 300$ each

I had a day off work today and spent some of it doing more research, spurred on by some of your suggestions. I've learned that there are at least 2 other manufacturers of these screw piles (Maclean and ECP). My original search may have been too specific, so I will re-visit some of the utility suppliers tomorrow.
 
Check also "Grain Bin Anchors".

I've always wondered how to design the helix to the shaft... without doing a FEM study. Anyone have any suggestions?

Have you looked for overhead line contractors to see if they have some in stock or know where to get them.


Or google Pole Line Contractors


I wouldn't think the anchor in your picture could hold 4000lbs in sandy soil. Is it maybe the 6" or 8" one?


Yes, duckbills are generally too small for a single one to work. I didn't realize manta rays were a thing, just though they were bigger duck bills. But, to increase capacity you can drive in multiples all at different angles and group the cable connections all together.

With care, I believe so. It's a 6" plate. Being 5 feet down helps, the column of soil is pretty high.
 
Yes, the pole-line contractors could put them in, but ironically that would mean having a second contractor come to do the job. I've already got a guy coming to install the screw-piles, and his equipment will drive in the guy anchors if I just have them ready when he's here (next Wednesday). So technically, that's a solution, but way more expensive.

It's getting really annoying that search after search turns this up in US websites for 50 bucks each. My hurry, plus Hoser tax, will run me about 100$ each.
 
If you're looking for an epoxy coating of any longevity, you should look into a proper high build zinc rich epoxy system. Any longevity requires time and money... no easy way out. Epoxy coatings often have significant 'cleaning' requirements... it all depends on how long you want them to last, and what your soil is.

They have to last long enough for everything to become used to being properly guyed. 😀

If only temporary... like a month or so, do they need any coating system? I've done multistorey buildings without primer...
