This Unusual Traction Engines page doesn't include the vehicle in the post, but has some similar ones like this:

The Hornsby steam crawler: 1910

This machine was shipped to Canada from England in 1910, being sold to the Northern Light Power & Coal Company for use hauling coal to the Klondike gold fields in the Yukon, where it worked until 1927. This was the only sale, and the Hornsby company became disillusioned with their "chain track"and sold the patent rights to the Holt Manufacturing Company in 1914.
