Discussion. Description of a Method of Rolling Bars for Suspension Bridges and Other Similar Purposes.

Abstract

ROLLING BARS FOR SUSPENSION BRIDGES.275 derangement commenced, as described in Mr. James Walker's report, after the accident.The chains for the bridge at Kieff in Russia, erecting by Mr. Vignoles, were manufactured on this new system ; and the chains for lifting the Conway Tubes, as alw those to be employed for the like purpose at the Britannia Bridge, over the Menai Straits, were made at Rotherhithe on this plan.

The construction of the Kiev Suspension Bridge 1846–1853

“…The deck cross-beams are hung by twin hangers from alternate chains. A particular innovation at Budapest, which would also be adopted by Vignoles at Kiev, was the use of fully rolled chain links, in which the eyes were part of the same rolling (see section 3.5, below) (Howard, 1849 The construction of the Kiev Suspension Bridge 1846-1853 Vignoles brothers, and discussed the form of their partnership. After a pause of several days, while they established the budget and firmed up the wording of the proposal, the journey recommenced, reaching St Petersburg on 1 February.…”

“…In 1845, Mr Thomas Howard, of the King and Queen Iron works at Rotherhithe on the Thames, had devised a method of rolling suspension chain links that avoided the need for separately welding the eyes. The works was presently engaged in making 5000 links for the Budapest bridge (Howard, 1849 The construction of the Kiev Suspension Bridge 1846-1853 Vignoles would be tested using a proving machine developed for the purpose.…”

“…He attended the ICE when Thomas Howard presented his paper on rolling bars for suspension bridges (Howard, 1849); he visited the Britannia Bridge tubes at Bangor, which had been installed by Robert Stephenson while he was out of the country; and he visited Coulthard to discuss the swing bridge designs, which were to incorporate wrought iron beams.…”
