Generally bulldozers are believed to be the most heavy-duty machines on the market. Bulldozers are incredibly strong and the best choice for shifting large amounts of dirt on sites where there are wide open spaces, rough grading and grinding rock. Bulldozers are easily identified by the huge blade at the front of the equipment that is controlled with the use of hydraulic pistons.
Bulldozers arent just used in construction. Militaries around the world also use these machines. One notable military bulldozer is the Israel Defense Forces Caterpillar D93, nicknamed Doobi. This bulldozer was used to demolish structures during combat.
