CRANES (so called from the resemblance to the long neck of the bird, cf.
Ducks, cranes and other aquatic birds abound in the delta.
Machines used for lifting only are not called cranes, but winches, lifts or hoists, while the term elevator or conveyor is commonly given to appliances which continuously, not in separate loads, move materials like grain or coal in a vertical, horizontal or diagonal direction.
The use of cranes is of great antiquity, but it is only since the great industrial development of the 19th century, and the introduction of other motive powers than hand labour, that the crane has acquired the important and indispensable position it now occupies.
In all places where finished goods are handled, or manufactured goods are made, cranes of various forms are in universal use.
