Green double friction drum steam donkey engine winch, Hyde Street Pier entrance, Fisherman's Wharf, San Francisco, USA

A nearby information board about a Steam Donkey Engine near this exhibit reads: 'Donkey engines ... were common along the waterfront from the 1880s into the 1920s. These portable steam winches were used as auxiliary power for loading and unloading cargo. The name 'donkey' comes from the fact that the engines replaced horses as a power source for cargo handling. The term was also applied to similar engine and boiler units carried aboard ship. Donkey engines were also employed in construction work, and in industries such as lumbering and mining. This engine was used until 1968 aboard a derrick barge belonging to the Port of Oakland.' The engine was built about 1920, by the American Hoist and Derrick Company, at St Paul, Minnesota. The engine type is a two cylinder horizontal and the winch type (seen here) a double friction drum.
