The IDF used armoured bulldozers extensively during Operation Rainbow where they were used to uproot Gaza Strip smuggling tunnels and destroy residential neighbourhoods, water wells and pipes, and agricultural land to expand the military buffer zone along the Philadelphi Route. The most widely documented use is the Israeli Defence Forces' (IDF) militarized Caterpillar D9, for earth moving, clearing terrain obstacles, opening routes, and detonating explosive charges. Dozer blades may be mounted on main battle tanks to clear antitank obstacles or mines, and dig improvised shelters.Īn armored IDF Caterpillar D9 bulldozer used by Israel Defense Forcesīulldozers employed for combat-engineering roles are often fitted with armor to protect the driver from firearms and debris, enabling bulldozers to operate in combat zones. Dozer blades with a reinforced center section for pushing are known as "bull blades".ĭozer blades are added to combat engineering vehicles and other military equipment, such as artillery tractors such as the Type 73 or M8 Tractor, to clear battlefield obstacles and prepare firing positions. The towed Fresno Scraper, invented in 1883 by James Porteous, was the first design to enable this to be done economically, removing the soil from an area being cut and depositing where needed as fill. Sometimes, a bulldozer is used to push or pull another piece of earth-moving equipment known as a " scraper" to increase productivity. All can be lifted, some, with additional hydraulic cylinders, can be tilted to vary the angle up to one side. It is typically used for pushing large rocks, as at a quarry.īlades can be fitted straight across the frame, or at an angle. combination ("S-U", or semi-U), shorter, with less curvature and smaller side wings.universal ("U blade"), tall and very curved, with large side wings to maximize load.straight ("S blade"), short with no lateral curve or side wings.Komatsu bulldozer pushing up to 7 m 3 with semi-U tilt dozer The bulldozer's primary tools are the blade and the ripper: These traits allow bulldozers to excel in road building, construction, mining, forestry, land clearing, infrastructure development, and any other projects requiring highly mobile, powerful, and stable earth-moving equipment.Ī variant is the all-wheel-drive wheeled bulldozer, which generally has four large rubber-tired wheels, hydraulically operated articulated steering, and a hydraulically actuated blade mounted forward of the articulation joint. Bulldozers have transmission systems designed to take advantage of the track system and provide excellent tractive force. Extra-wide tracks are known as swamp tracks or low ground pressure (lgp) tracks. Wide tracks also help distribute the vehicle's weight over a large area (decreasing ground pressure), thus preventing it from sinking in sandy or muddy ground. ![]() ![]() The tracks give them excellent traction and mobility through very rough terrain. ![]() Typically, bulldozers are large and powerful tracked heavy equipment.

Talk to an Expert About New Cat Dozers at Competitive PricesĪt Blanchard Machinery, our team is standing by to help you find the right track type tractor you need to best fit the job at hand. Initially, Cat dozers were named with letter modifiers to differentiate machines that existed within the same size class, such as the D6T, D6N and D6K2. Now, the dozers have dropped the letters following the numbers and the number correlates directly to the horsepower of the machine. The change is being implemented to simplify for our customers how machines compare to one another within the dozer lineup. Same Performance You Trust.Ĭat ® dozers are already known for changing the equipment game, so now it's time for these industry-leading machines to get some upgraded names.
