Jib

Used to lift molten iron to molds where it was cast into pipe, jib cranes were the sole means of conveyance in the pit-casting process. When pit casting was replaced by centrifugal casting in the 1920s, many pits were filled and the cranes were used to produce cast iron fittings or general maintenance work. Only one jib crane remained at the American Cast Iron Pipe Company in recent years, and it was probably the last pit-cast jib crane to operate, which it did until it was given to the Sloss Furnace Museum in early 1986.
