I used to make Satellite Dish stands you know back in the C-Band days, when dishes where 8 10 or even 12 feet across. (the little ones you see now are Ku -band - Pronounced Q) This relates to the problem at hand... One of these dishes would weigh in at around 200 - 320 lbs, but because they where so large wind loads become a problem thus it is difficult to predict how much weight would actually be on one leg of the stand at any given time... You have a similar problem. There are 2 simple solutions one elegant, the other ugly... The simple solution is to bolt it to the wall... The ugly solution will be something like this.... A steel pyramid stand with a pivot at the apex of the pyramid. The pyramid should stand 3 1/2 feet to 4 feet tall.. At each of the 3 corners that are along the floor, you should put a pad or leg that weights (each) 300 lbs or so... (the one on the back leg should weigh more if possible) We're over engineering because we have an uncertain weight, with uncertain forces suddenly shifting that weight. We want the center of gravity to be as low to the floor as possible, and in the center or to the rear of the pyramid - to prevent the pyramid from tipping... Woa --- hold the phone... Better Idea just occurred to me... Get 2 steel telescoping support beams - you know the type of things that go into a basement to hold up the house? ... (hopefully this is going into a basement) put both beams close together, and under a floor joist, once they're secured in place, bolt the pivot in between the 2 beams... then bolt your wheel thru the pivot... The pivot and bearings you could get from princes auto, which sells all kind of auto supplies, including all the gear necessary to build your own utility trailers... The pivot you want would be the wheel bearing for a small utility trailer - good for up to 1200 lbs... That, I think is an outstanding idea -
