A simplified model of wrought iron sheer legs installed in the Victoria Docks, London, in 1856, designed to lift 70 tons. Original designed by Robert Mallet. It was installed on the cobbled dockside. I recommend using Andi06's built-in cobbles (kuid2:122285:1509:2) for the ground texture, or one of barry's cobblestone textures (kuid:36638) available on the DLS. Utilizes plans published in The Engineer magazine.
