The post I was replying to read like you were saying there had to be something like a mini waterfall. I never said any such thing!!!! But in an odd way, you have hit the nail on the head as to why the bridge could never have been used for a hydraulic ram (more below). A 'head' of water can be provided by a pipe bring the water some distance as we've both already agreed. It CAN also be provided by a waterfall or even a header tank (not that I mentioned any means of how the drop was achieved to the ram despite what you erroneously thought). But to go back to that bridge which is high above an irrigation channel. As you probably know, irrigation channels are a body of slow moving water and they are on very gently slope. Just how far upstream do you think the inlet pipe would need to be to provide a head for a hydraulic ram situated that high above the water on that particular bridge? That bridge never held any ram because as we both know, there needs to be that 'drop'. How many miles would a pipe have been run back up that irrigation channel to allow a drop to run a ram sitting up on that bridge? Referring to the photo, I disagree with "high above". Well you may disagree but it'd be at least 4 ft to the top of a hydraulic ram situated on that bridge. Except ... it's the bridge you refer to as being "... high above an irrigation channel." It's unknown whether the hypothetical ram was situated on the bridge or suspended from it. http://personal.morris.umn.edu/~webb...ndeBridge2.jpg One of the puzzling things about the possibility of it having been used as a conventional bridge is that it was set down into cuts in the banks. Also, the previous exchange in context was: John Gilmer wrote: "I suspect that the "bridge" served to hold a "hydralic ram" which uses the velocity of the water to pump a small portion of the water to the level of the surrounding fields." Farm1 replied: "Nope. Hydraulic rams need a head of water above the pump so that the water drops into the ram. - its the action of the water falling into the ram that makes the pumping happen." Part of the reason I interpreted your "drops" and "falling" literally was that you were explicitly disagreeing ("Nope") with what John G wrote. Am I now missing posts from you too? I haven't seen anything from you about how you were interpreting what I wrote, but if you'd asked I'd have told you that "Nope" was in reference to the structure being used to hold a ram. My participation in the thread had been about the OP's and other bridges, not pumps/hydraulic rams. So, you didn't miss any (previous) post of mine in which I commented on hydraulic rams. Now, I am confused. Are you saying you meant the "Nope" to refer to the bridge? |

RW From looking at those new pics, I'm confused to what it's original purpose was. It's a bridge but not very wide and built to hold substantial weight. Over built even. It's original intention was probably not to hold any kind of pump, etc. It almost looks like a bridge for a narrow gauge train. Something heavy. Guessing the lift, etc were added after the fact for some reason. Just my thoughts. |

RW Thanks for the follow-up. The rivets are consistent with it being a pony truss bridge ... early 1900s. The electrical boxes (3976) belong to the Agralite Electric Coop http://www.agralite.coop/ The boxes have "No PCBs" labels, which date them as having been installed after the late 1970s PCB phase out. |

Harry thinks a 'normal person' wouldn't see that as a drop, but I know that you'd know my background well enough to know that I'm quite normal in the rural Australian sense but probably not in an urban or American sense. Having seen so many silly questions online such as can someone drink rainwater, or drink water collected off a roof or (grasp!!) even use it on vegetables, I'm always stunned at such lack of awareness of water and it's provision to house, animals and garden.

If you'd spent a few minutes at groups.google.com before you dug yourself in deeper, you'd have found that the OP had never posted to misc.rural before. If you're bored (or whatever) with the thread, kill filter it instead of hassling people in another ng; the OP was a "third party" whose "home" is Google Groups.

Well you may disagree but it'd be at least 4 ft to the top of a hydraulic ram situated on that bridge. Except ... it's the bridge you refer to as being "... high above an irrigation channel." It's unknown whether the hypothetical ram was situated on the bridge or suspended from it. Well I can see your point out the position of this hypothetical ram, but to go along with that, I'd have to ignore what farmers do in real life which is to go with the most practiacl solution to save themselves time both in the build and in the maintenance. If there is a perfectly good flat platform on which to put a pump why go to the trouble of rigging up a way of suspending an hydraulic ram below such a structure? A platform out the side may be a possibility but I'd say from the new pics that it's always been used the way it is shown. Probably bought cheap in some sort of clearance sale by whoever had it originally for whatever they had it for originally. I'm not going to argue with that, since 5/26 I posted: "Consider the possibility that "your" bridge was repurposed from its original use/location. As those bridges were phased out, some were probably free for the taking." g http://personal.morris.umn.edu/~webb...ndeBridge2.jpg One of the puzzling things about the possibility of it having been used as a conventional bridge is that it was set down into cuts in the banks. Also, the previous exchange in context was: John Gilmer wrote: "I suspect that the "bridge" served to hold a "hydralic ram" which uses the velocity of the water to pump a small portion of the water to the level of the surrounding fields." Farm1 replied: "Nope. Hydraulic rams need a head of water above the pump so that the water drops into the ram. - its the action of the water falling into the ram that makes the pumping happen." Part of the reason I interpreted your "drops" and "falling" literally was that you were explicitly disagreeing ("Nope") with what John G wrote. Am I now missing posts from you too? I haven't seen anything from you about how you were interpreting what I wrote, but if you'd asked I'd have told you that "Nope" was in reference to the structure being used to hold a ram. My participation in the thread had been about the OP's and other bridges, not pumps/hydraulic rams. So, you didn't miss any (previous) post of mine in which I commented on hydraulic rams. Now, I am confused. Are you saying you meant the "Nope" to refer to the bridge? Ah! I see what you mean! My first thought was about that bridge not being a site for a ram. So, yes, I did mean "Nope" was in reference to the structure being used to hold a ram. I don't believe that bridge held a ram and now I've seen more pics, I'm even more of that view. But as I think you're poitning out, since I don't believe that bridge held a ram, then my nope must also refer to a ram (but it was the bridge that I was thinking about). OK ... I think. Since we are discussing water, how did your summer go water-wise? |

It looks more to me like that is a bridge used to support a big pump for some kind of irrigation. Note the pump in the middle with the overhead to rise the pump. Yes exactly. It sure looks like a big ass electric motor on the left with a cover over the belt drive part of the pump on the right. Looks like electrical conduit going to the electric motor, although the setup looks older than conduit, it may have been upgraded at one time. Like others said, the bridge itself was probably used and moved the this location since it's probably 10 or more times stronger than it needed to be. |

Check into any districts that may have built the ditch. It sounds like there must be a fair network of these ditches. More pix (full-sized) of the bridge as promised, including close-ups of the bolts/rivets for age estimation. Shot of item lying on the ground was the best I could get. http://personal.morris.umn.edu/~webbrl/SundeBridge/ Don't know what to make of the electrical systems. Are some older than others? Does the meter look up to date? What's with the row of bunkers (?) with the high voltage warnings? All that for this bridge? Have I mentioned there's a power substation on the opposite side of this farm, in the northeast corner? Coincidence? Brought my cousin along. Lived on a farm in the early 1970s. She says an older tractor might fit across the bridge but not a new one and NEVER a combine. Meanwhile, the current owner of my great grandma's farm says it was indeed used for drainage and, if I understood him correctly, irrigation. Farmer to the west has/had light sandy soil and LOTS of water (from wells) AND an irrigation system. He needed to drain off the excess water. Farmer to the east agreed to allow the water to drain into the ditch which he could then use to irrigate his own land. In return, he received permission to use the adjacent, parallel (to the ditch) access road for hunting. Does that all fit/make sense? Still not sure when it all actually happened... Oh gee, just after I look better and comment on the first pics, here are high res ones! I doubt if anyone would deny there is a big electric motor to drive a pump, and definitly electrical conduit. The high voltage boxes look like every day transformers normally used when the power lines are underground. The question is why so many at one place? One would surely power the pump. The narrow width could be again because it is a used bridge. The trusses were used but they put it together again narrower than original. It didn't need to fit a tractor, no tractor was going to squeeze past the pump anyway. |
