A steam donkey or donkey engine is a steam-powered winch once widely used in logging, mining, maritime, and other industrial applications. Steam-powered donkeys were commonly found on large metal-hulled multi-masted cargo vessels in the later decades of the Age of Sail on through the Age of Steam, particularly heavily sailed skeleton-crewed ...
The traditional form of steam donkey (as a mobile winch used in the logging industry) married a vertical boiler with a steam engine on a rigid base fitted with skids for mobility. Since the ground to be traversed would be rough and rarely level, the water-level -tolerant design of the vertical boiler was an obvious choice.
They were widely used, in the age of steam, as a small donkey boiler, for the independent power of winches, steam cranes etc. [1] [2] [3] The boiler has the advantage of simple robust construction, in particular requiring little regular maintenance. It is relatively inefficient, which was not a serious drawback to the purposes for which it was ...
The winch or grapple holds the trees while the skidder drags them to a landing area. Cable skidders are more labor-intensive than grapple skidders because someone (the operator or a second person) must drag the winch line out to the logs and hook them up manually. Nowadays, cable skidders are less popular than in the past.
The Washington Winch sits in the forests of eastern Victoria near Swifts Creek and is also known as the Washington Iron Works Skidder. Its rusting relics are close to Bentley Plain and the Moscow Villa hut which was built in 1942 by firetower man Thomas William Ah Chow. It was a steam-powered logging skidder, or cable winch.

Doble steam-car boiler: donkey boiler: A donkey boiler is used to supply non-essential steam to a ship for 'hotel' services such as heating or lighting when the main boilers are not in steam, for example, when in port. [3] Donkey boilers were also used by the last sailing ships for working winches and anchor capstans. See also auxiliary boiler.
Instead, a winch – known colloquially as "The Lidgerwood" on some railroads – would move the locomotive while cutting heads were mounted on brake shoe brackets and forced against the wheels. As the locomotive moved against the cutting heads, its wheels were cut back to a desirable profile.
