SC Montana where General Custer should've stopped | Look at Big Sky Pipe and Suupply out of Great Falls MT. We bought 14 crossings last year. Their out of 2 7/8" and the part the tires run on are pieces of 2 3/8" oil field pipe , not tubing, Also looks at Johns Welding out of Nebraska, they do theirs with angle iron. Thes pipe ones we bought were closer and a lil less expensive. He gave a discount for ordering early. We had on e 40 footer, two 35 footer and the rest were around 30'. The longer ones were used on the inside toweres ( # 2 and # 3) so make sure to make them a foot wider to allow for more turning as the pivot crosses the bridge. We set our end son 4' x 5' concrete pads with anchor loop in the concrete so they should never move. |
