The D8H in 1969, shown here with a standard hydraulic bulldozer blade. Peterson engineers would directly influence Caterpillar Research more than any other outside source at the time. Tested with a variety of attachments, one would eventually be equipped with a custom 22-foot wide bulldozer blade. The Twin D8 above was one of only three developed by Peterson Tractor’s Special Equipment Services between 19. With thousands of units in the field, the D8 dropped the “R” in its designation and was a top seller in Caterpillar’s stable.īefore the larger D9 was created, any demands for a more powerful tractor were sometimes met with unique solutions. Its operating weight was 50,025 lbs.īy the 1950s the D8 would have style changes to the body and the ever-reliable D13000’s horsepower was increased 150 at the drawbar. Based on a Caterpillar Seventy-Five with a little more horsepower, it wouldn’t be long before it was updated with the D13000 six-cylinder diesel engine, pushing it to 95 drawbar horsepower and 108 belt horsepower. Military versions of the D8 found their way to the theaters of World War II and provided critical support for the construction needs of American forces. Each year saw successive improvements in design, features and horsepower.Īs the construction industry grew hungry for machines to build America, the D8 tractor catered to their desires with reliable performance. This included products such as cable-operated bulldozer blades, canopies, push blocks, pipelayer cranes, and towed scrapers. As the years went by, a multitude of attachments and modifications would be made available from both Caterpillar and allied equipment manufacturers. Please get in touch with us now to know more details about bulldozers, we have cultivator, drilling rig, wheel loader, excavator, roller, motor grader and other series for sale.First introduced in 1935 as the RD8, this tractor was immediately popular for its balance of size and power. HBXG is the pioneer of the track bulldozer manufacture in China. Centering on steel making, we are also involved in mineral resources, financial services, modern logistics, iron & steel trade and equipment manufacturing. some of the best tasks for PAT shovels include scraping, land clearing, grading, backfilling and leveling. Like angle blades, these blades are mounted in the center of the panel. The driver controls the blade from the cabin and can tilt, incline and lift in virtually all directions. The PAT blade is one of the most versatile blades due to its ease of maneuverability and multifaceted movement. Some of the best tasks for an angle blade include staking, shaping, stripping and trenching. It is an excellent choice for projects involving soft to medium-hard density soils, snow and gravel. Keep in mind that this blade may spill because it has no flanks. Therefore, the corner blade is considered a bi-directional blade. Its position is useful for moving debris to the side, as it can be angled close to 30 degrees to the left or right. ![]() This type of blade is mounted in the center of the dozer panel. su Some of the blade's best tasks include raising, moving heavy loads, tripping and trenching. It is best suited for pushing soft to medium density sand and soil. This blade uses a tilting stabilizer bracket and one or two hydraulic tilt cylinders attached to the lower back of the blade. This design makes it ideal for long-distance dozing. It is narrower and less curved than a regular U-blade, and it has smaller flanks. This blade combines the features of an S-blade and a U-blade, giving it greater penetration and better overall versatility. some of the best tasks for U-blades include trenching, hauling, pushing and raising. ![]() It is the largest blade type in height and width and is best suited for soft to medium density soils. Like the S-blades, they are attached to the lower corners of the blade. The wings prevent material from spilling while in motion. U-blades have large flanks and a curved shape that is ideal for pushing material across long stretches of land. some of the best tasks for s-blades include stumping, backfilling, grading and late soil. The disadvantage is that its straight shape limits the lift and load capacity of the dozer. Due to its shape, the straight blade is best suited for fine grain and medium to hard density materials. The blade is attached to the arm at the lower corner of the blade. The S-blade is the shortest type of blade available for bulldozers and has no flanks. We have listed the most common types below. Different blades have different uses, can handle different types of materials, and can handle a variety of load weights. The types of dozers mentioned above can be further categorized by the blades used.
