Hello to all, I have a Hy Gain HG-52 SS 52 foot crankup. It's been up for a number of years. The concrete base is as per specs. 42" on a side and about 5'6" deep with about 6 more inches of concrete
Would it be feasible to engineer new 'dog ears' to attach to the present dog ears using the holes vacated by the tower bolts? The tower then would bolt to the new dog ears with new bolt holes etc. I
You don't mention the ear orientations but if you tilted the tower up on installation one would think the matched pair of ears are away from the house and the single is towards the house. I assume th
Correction - for the tower to tilt (at least the Tri-Ex and USTs I have), some spacer plates the thickness of the ears on the foundation are needed between the riser plates and the tower ears, since
I don't like being the one to say "the emperor has no clothes" but the right thing to do is get a geotechnical engineer to check the soil conditions and design a proper footing that will not settle.
With a small 52' crankup, you can probably live with quite a bit of lean. The main problem is whether it can still go up and down without binding. The additional stress on the tower from leaning a li
Art, How much lean are you seeing? There are number of possible solutions depending on your capabilities and how much time and $$ you are willing to spend. 73, Gerald K5GW In a message dated 4/17/201
The lean is linear, the force/leverage is not. OTOH for that small a lean I doubt it'd cause much of a problem from sections sliding. 73 Roger (K8RI) _______________________________________________ _
I have the same tower and same situation. I have not determined the exact amount of lean, ie dropping a plumb bob from the top, etc. I also used the base dimensions in the instruction manual, and the
It might be interesting to talk to one of those foundation repair companies. Mudjacking, and the like are expensive, but it does work. 73, Joe kk0sd Would it be feasible to engineer new 'dog ears' to
I completely agree with Joe. You need professional advice from a goetechnical / civil engineer. This is not a question that can be answered by suggestions or opinions offered remotely, ie without see
There are still a few unknowns so please pardon the many weasel words. Also, I can only deal in generalities. "I think" one of the important things would be to determine *why* the base has shifted an
