Features

Mainframe Strength

Helping you get more done with maximum availability, the durable design of the mainframe makes repair and maintenance easy. The D11T/D11T CD mainframes are built to absorb high impact shock loads and twisting forces during severe dozing and ripping applications. It is not uncommon to see these machines rebuilt several times using the same frame, with only minor welding.
  • Frame rails have a full box section design which keeps components rigidly aligned.
  • The main case, equalizer bar saddle, and front cross member are heavy duty steel castings incorporated into highly loaded areas of the mainframe to improve stress distribution for improved durability.
  • Top and bottom rails are made from continuous rolled sections which provide superior mainframe durability.
  • The main case elevates the final drives well above the ground level work area to protect them from impact loads, abrasion and contaminants.
  • The pivot shaft and pinned equalizer bar maintain track roller frame alignment and allow the roller frame to oscillate for smoother ride.
  • Heavy cast saddle has a ribbed design which increases frame life.
  • Tag-link blade mounting brings the blade closer to the machine for excellent maneuverability, machine balance and blade penetration.

Equalizer Bar End Pins

Proper grease lubrication on working surfaces can significantly extend component life and help lower maintenance cost.
  • The remote lubrication for the D11T/D11T CD is performed from a service point conveniently located on the left hand fender and allows an operator or service technician to lubricate both the left-hand and right-hand equalizer bar end pin bearings and pins from one service point.
  • Adding the optional autolube system allows the operator to tailor the amount of grease needed for each application by volume and service interval.

Carrydozer Frame

The Carrydozer frame is specifically designed to accept the additional frame loads generated by the unique Carrydozer blade design.

C32 with ACERT Technology

The Cat C32 engine with ACERT Technology delivers power and reliability, ensuring top performance, high productivity, and exceptional service life.
  • The C32 ACERT engine performs at full rated net power of 634 kW (850 hp) at 1,800 rpm with a high torque rise of 21 percent, allowing the D11T to doze through tough material.
  • Matched with a high efficiency torque divider and electronically controlled power shift transmission, it will provide years of dependable service.

ADEM™ A4 Engine Controller

The ADEM A4 electronic control module manages fuel delivery and air flow to get the best performance per liter (gallon) of fuel used.
