Roller frames are tubular to resist bending and twisting, with added reinforcement.Rollers and idlers feature symmetric Duo-Coneā¢ seals for long sealing life to prevent oil loss and dirt entry.Integrated carrier roller mount is fabricated into the track roller frame making it easy to add the optional carrier roller in the field.Higher traction means less slippage, better balance, and a smoother ride. Bogie suspension allows the track to conform to ground condition, providing up to 15% more ground contact, especially in hard, uneven terrain.This design transfers implement shock loads to the mainframe, so final drives, axles, and steering components are isolated from harsh impact loads commonly seen in large track-type tractor applications. These benefits translate into higher production and longer component life. The elevated sprocket and suspended undercarriage work together, increasing traction and giving the operator a smoother ride. Tag-link blade mounting brings the blade closer to the machine for excellent maneuverability, machine balance and blade penetration.Heavy cast saddle has a ribbed design which increases frame life.The pivot shaft and pinned equalizer bar maintain track roller frame alignment and allow the roller frame to oscillate for smoother ride.The main case elevates the final drives well above the ground level work area to protect them from impact loads, abrasion and contaminants.Top and bottom rails are made from continuous rolled sections which provide superior mainframe durability.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.Frame rails have a full box section design which keeps components rigidly aligned. It is not uncommon to see these machines rebuilt several times using the same frame, with only minor welding. The D11T/D11T CD mainframes are built to absorb high impact shock loads and twisting forces during severe dozing and ripping applications. Helping you get more done with maximum availability, the durable design of the mainframe makes repair and maintenance easy.
