Aluminium support beams were fixed as propped cantilevers to the underside of the Forth Bridge Main Viaduct Girders.
Suspension wires replace the standard scaffold tubes and were hung from neoprene lined hanger brackets ready to support the suspended scaffold, which was rapidly constructed from the bottom upwards.
Constructing a suspended scaffold from the top down would add up to 65% to the labour costs and considerably to the weight.
The 13mm rope used here replaced the vertical suspended tubes which would require passing down from the top and tension splicing at every joint. Splicing scaffold tubes at each tension joint is heavy, time consuming and difficult work in top down construction.
