Today aerial tramways make it possible to soar above the terrain in a tram/cable car or chairlift. Before tramways carried people, they were used in the mining industry to transport ore quickly and economically over rugged, inaccessible terrain.
The concept of aerial tramways began in the early 1700s, but the European introduction of wire rope in the 1830s led to increased development and use. Wire rope is several strands of steel wire twisted to form a cable. Due to lighter weight and strength, it soon replaced hemp rope in many applications, including mining. Although numerous aerial tramways for mining were built worldwide, it wasn’t until after the Civil War that their U.S. construction expanded.
