Hydraulics Powers One-off Chinese Swing Bridge

Posted August 31, 2014 12:00 AM by Engineering360 eNewsletter

When Chinese engineers built a highway overpass, they could not disrupt the high-speed rail line the roadway would straddle. Instead they built the bridge parallel to the tracks. Once completed, they hoisted the span 15 m (49 ft) onto a pivot and support ring, and hydraulically swung the 17,000-ton assembly 106° in 90 minutes. The ends of the bridge were then permanently mated to the adjoining roadway segments.

Clever, yes. Lets see what integrity (under table deals and quality for $ or yen trade OFFS) is. And the only why it will be exposed is time.

It's a real inventive way of doing things. Larzep Hydraulics is always helping engineers out with that kind of specialized equipment thats why I always opt to them but its hard to find a distributor in northern-NA so to speak, I end up shipping from mexico. I actually came across a NA distributor of Larzep recently, after some digging in my history here it is haha

www.cratoscanada.com

I am under contract with a company right now to do a bridge lift, and he quoted me almost seven percent under the other distributor of simplex.

Anyways, sorry for the ramble, just thought some of you would be interested!
