"A Crane is a machine for lifting weights, worked either by hand or by steam, or by hydraulic power. The most common hand form consisting of an upright revolving post and projecting arm, the jib with a fixed pulley at its extremity. The lifting chain or rope is secured to the weight, passes over the fixed pulley, and then round a drum or cylinder; suitable toothed-wheel gearing worked by a handle revolves this drum, and thus winds up or unwinds the rope or chain, and so raises or lowers the weight."—(Charles Leonard-Stuart, 1911)
