#475 komatsu dozer vs d11 series

The D11T provides an ergonomically designed cab and electro-hydraulic controls, making the operator more comfortable and efficient.The D11T has standard open labyrinth seal guards to protect the final drive components when working in applications where mud packing is common.The blade tag-link design of the D11T keeps the blade closer to the tractor, improving maneuverability, tractor balance, blade penetration force, pryout force, and blade control.The D475A-5 requires pulling off the ROPS, cab, operator platform, and fuel tank to get the power module out. Komatsu uses a one-piece power module that is difficult to remove. The major power train components of the D11T are designed as separate modules that are easy to remove.The torque divider, offered by Caterpillar, provides a more efficient power train system over a broader operating range than a torque converter and does not require the operator to decide when to enable or disable lock-up capability. The D475A-5 uses a lock-up torque converter and a three-speed planetary transmission. The D11T has a torque divider and a three-speed planetary transmission.More track is located aft of the sprocket for better balance and improvements to traction and flotation while counteracting front-end rise during heavy dozing and drawbar work. Shock loads from the blade are directly carried to the mainframe rather than through the final drive cases. The elevated sprocket raises the sprocket above abrasive materials, extending sprocket life.The D11T has better ride quality, especially in reverse, than the D475A-5 due to its fully suspended undercarriage and sprocket placement.The mainframe is built to withstand high impact loads induced by heavy dozing and ripping in hard clays, shales, and rock.The D11T has outstanding durability due to frame design containing castings used in important stress prone areas and component placement, such as the suspended undercarriage that raises the final drives above the ground.The D11T frame is a fabrication featuring box section construction, and high strength steel castings in high stress areas giving it higher strength and durability.The low sound design focuses on sound absorbing fan blades, side enclosure with air duct, double hood, and viscous cab mounts. The main selling points of the D475A-5 are the lock up torque converter and low cab sound levels. The development of this tractor focused on operator comfort, sound levels, and reduced maintenance and repair cost. The D475A-5 is primarily used in mining and large-scale heavy construction projects. EPA Tier 2 engine, is the primary competitor for the D11T. The Komatsu D475A-5, first introduced in 2003 and updated in 2006 with a U.S. Combined with the Cat C32 ACERT engine for superior performance, fuel economy and meeting emissions targets, it keeps material moving with the lowest overall cost. The durable construction of the D11T is well suited for tough working conditions. The D11T combines power and efficiency with advanced technology for outstanding production at a lower cost-per-yard. EPA Tier 2 equivalent emission levels for sales outside of the United States and Canada. EPA Tier 4 Final certified and required for sale in the United States and Canada. The new D11T and D11T Carrydozer (CD) will be offered with two variations of the C32 engine with ACERT™ Technology. Caterpillar has taken every opportunity and designed the new D11T with the next generation in mind. With changing times comes new opportunities.

The R series tractors built on that standard while meeting more stringent Tier 1 emissions requirements. Since the D11N was introduced in 1987, it has become the standard of the industry for large construction and mining tractors. The Cat D11T builds on that expectation for performance, reliability, durability and operator comfort.
