In 1911 the Northern Pacific railroad constructed a Strauss heel trunnion of the Strauss bascule bridge company with the 2 dc motors of 25 horsepower the machinery was installed on the end of the bascule span, the struts attached to the counterweight bridge tower for a season until the late 1928 then Joseph B Strauss reversed or translate the arrangement.
Good luck, Robert. You aren't being picky.
Robert I understand what you are coming from however I'm not an engineer but a student with a prolific study of movable drawbridges in the past 14 years as well drawing them. I also read details of all bridge types I know that you aren't trying to be mean but even engineers makes flawed mistakes, I can admit I make mistakes sometimes, but here I had mention about the early design heel trunnion type that was constructed in 1911 with the struts attached to the counterweight bridge tower with the drive machinery installed on the bascule span, the span is heavy in the raised position and in the lowered position the counterweight is heavy, I assume that you viewed my work. However in the late 1920's the bridge had reversed as the strut attached to the bascule truss to support the counterweight while the machinery was installed inside the counterweight bridge tower. As the bridge is raised the counterweight is heavy then the span is heavy in the lowered position check out movable bridge engineering book by Terry L Koglin thanks.
I hope I'm not being too picky here, but:
"Bridge closed with the counterweight heavy with the drive machinery installed on the bascule span."
"The energy in the late 1920's transferred from the span to the counterweight and the drive machinery installed in the counterweight bridge tower, in the closed position the span is heavy for a better suited operation."
"Bridge raised the struts fixed to the bascule span returns back to the counterweight support system in most heel trunnion bascule bridge the struts supports the counterweight making the counterweight heavy"
I am an engineer who deals with technical language every day. What I snipped out and posted above makes no sense at all. Could this be translated to actual, technically correct English?
Wasn't the 1911 bridge torn down after they built them new 1932 bridge. Both spans existed side by side for a short time . The old one was replaced because the war Dept said the old bridge didn't have enough clearance.
