Steel-wireropes are also used instead of chains, and the working is thuseasy, and as nearly noiseless as possible. As a great part of thework of the crane is the coaling of steamers, for this purpose asecond hoisting barrel is fitted, and used for tipping up the ends 218 COAL-SHIPMENT AND THE LAYING-OUT OF STAITHE HEADS. of the wagons. This barrel may also be employed for working-light lifts when the crane is not used for coaling.
