Donkey engines like this one 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 there 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.
