. "Frank Bottrill (1 April 1871 \u2013 7 January 1953) was an Australian blacksmith and inventor, known for his giant \"Big Lizzie\" traction engine, thought to be at one time the largest in the world. It had a unique variant of the Dreadnaught Wheel design. Alternating bearing plates gave support to each wheel, allowing it to travel over soft ground without bogging down.This was an early attempt to solve the problem that was later addressed more effectively by the caterpillar track."@en . .
