#D475 komatsu dozer vs d11 series

The bulldozer may move only for a short distance or fail to move at all. 2) Bulldozer is unable to moveĬrawler tractors usually develop a problem where they cannot move forwards or backward as expected. The drain plug should be cleaned regularly to cushion this common problem. Though oil leaks may be caused by worn-out rings or gaskets, a build-up of dirt in the drain plug may occasion such leakages. However, oil leaks are a common problem that leads to the malfunctioning of the dozers. Apart from this, oil is used as a coolant for all transmissions, cylinders, and all other components. The hydraulic systems of the Komatsu D575A and the Caterpillar D12 rely on oil to transfer power from one point to the other. Oil and the oil system are among the most critical components in these dozers. Common issues for Komatsu D575A and the Caterpillar D12 1) Oil leaks For instance, the Komatsu D575A tractor increased the previous yard-per-hour operations from 375 yards to over 750 yards when it was introduced. The Caterpillar D12 has an Automatic Blade Assist feature (ABA), and a hydro-dynamic component that multiplies efficiency output by sending 25% of torque to the drive shaft directly and the remaining 75% through the converter.Īpart from these small size differences, the two massive tractors are designed to work in the mining and quarrying industries and all related environments to increase efficiency and operational capacities. It comes with comfortable and easy-to-control electro-hydraulic features, and an operator detection component that locks the system when the operator is entering or disembarking from the dozer. The Caterpillar D12 has an engine displacement of 1959 cubic inches and 850 HP.

Its rival, the Caterpillar D12 tractor is slightly shorter in height by three feet (it is 13.25 feet tall), and its blade capacity has a shortfall of over 15 cubic yards (its blade capacity is 74.9 cubic yards).

Contact area- over 100 square feet (9.4 square meters), exerting about 23 pounds per square inch of ground pressure, amounting to over 160 kPa of pressure.

The optional blades have 44.5 cubic yards (34 M3) and 58.8 cubic yards (45 M3) capacity respectively.

Optional semi-U or U- dozer blade both having either a single tilt or dual tilt cylinders.

Dig or carry a load capacity of 12 feet (3.6 meters) high, and 24 feet (7.4 meters) wide equivalent to 90 cubic yards or 69 cubic meters).

11 feet, 22,000pounds patented Super Dozer Blade.

Engine- 794.2 KW(1,065 Horsepower) and has two dedicated updates, the Komatsu D575A- 3SD, called the Super Dozer, and the Komatsu D575A-Bulldozer, commonly called the Ripper.

Other Komatsu D575A specifications include: It weighs an astonishing 336, 420 pounds (152, 660 kg). It is 38.4 feet (11.71 meters) long, 24.2 feet wide (with a standard blade), and comes along with a 2.4 feet (0.74) ground clearance. The Komatsu D575A is a 12-cylinder super-sized crawler whose height is over 16 feet high (4.9 meters), that is, ten feet more than the height of an average, or, two-and-a-half 6-foot men put on top of each other.

#D475 komatsu dozer vs d11 series

The Komatsu super crawler tractor is identified with the letter D, which stands for Dozer and is then followed by a model number (for example 575A), the series number (-2 or -3), and the engine configuration (SD or SR). However, although, the Komatsu D575A's gigantic size and operational volume have made the crawler the undisputed champion among the crawler tractors, the Caterpillar D11 is not far behind.

The two giants compete favorably both in size and operational capabilities. The Komatsu D575A and the Caterpillar D11 are arguably the largest crawler tractors in the market today.
