This report updates our May 2015 crawler dozer and crawler loader equipment analysis. Crawler dozers, commonly known as “bulldozers”, are one of the most immediately recognizable pieces of construction equipment. Dozers are one of the earliest off-highway machines used for moving material from one location to another. They are indispensable machines for certain projects and today are found in construction, mining, quarrying, forestry, road building and maintenance, land clearing, and infrastructure applications. Crawler loaders too harken back to the evolution of early construction machinery, however, today they have largely been replaced by wheel loaders with their higher speed and ease of movement. They are tracked like crawler dozers, but are equipped with a loader, rather than a blade, for loading and digging. Crawler loaders were popular workhorses around construction sites seventy plus years ago when they were first introduced. However, demand for these machines has diminished considerably since the introduction of wheel loaders in the 1950s and 1960s.
