Machines belonging to this category are otherwise called a bulldozer, which pushes earth and rocks with a blade installed at the machine’s front end. Large- sized crawler dozers normally have a set of claws called a ripper that is installed at the machine’s rear end and can crush a hard rock. Swamp bulldozers are equipped with an undercarriage that is configured to enable them to freely move around on a marshy land. As a fellow machine, there is a pipe- laying machine that lays down a large steel pipe in the construction of a pipeline and a dozer shovel (crawler loader) for loading.
