Taper suspension bridge Taper suspension bridge The taper suspension bridge (also known as the taper principle) is a bridge design patented by James Dredge in 1836. On a conventional suspension bridge the whole deck is suspended on vertical cables, rods or chains from a single cable or chain slung between two supporting towers. The taper suspension bridge that James Dredge devised in the early nineteenth century differs from the conventional suspension bridge design in that it is, in effect, a double cantilever bridge. Each of the opposing cantilever systems are self-supporting. The cantilever half-deck structure of each cantilever is suspended on angled chains
Cable reel Cable reel A cable reel is a round, drum-shaped object such as a spool used to carry various types of electrical wires. Cable reel which can also be termed as drums have been used for many years to transport electric cables, fiber optic cables and wire products. Cable reels usually come in four different types, each with their own uses: wood, plywood, plastic and steel. Wooden drums come in three different varieties: steel-tyred for multiple use, export for sending abroad, and one-way drums for single trip use. Wooden drums can carry heavy loads and are constructed in resinous wood. Discarded
