For the purposeof tabulating, hoisting engines have been arbitrarily divided intothe following classes (See Table 118): SINGLE CYLINDER ENGINES 1. Reversible link motion, single friction drum, ele- docks, stevedores, ships, Class,vator sheaves. Adapted to coal yardscentrifugal pumps, pile driving, etc. Class. 2. Single friction drum. Adapted for same uses asClass 1 engine. Class 3. Double friction drum. Suitable for general hoistingpur
