Over 310 hp, Caterpillar’s large Dozers are engineered for demanding work. Durable construction is ensured for tough working conditions. Elevated sprockets increase productivity, simplify maintenance, reduce downtime with modular components and raise final drives and associated power train components out of the work environment. Cat® Track-Type Tractors keep material moving with the reliability and low operating costs expected from Cat tractors.

Cat® Large Dozers Highlights

  • Rugged, powerful and easy-to-service Cat® engines have high torque rise and meet or exceed emissions requirements.
  • The Advanced Modular Cooling System (AMOCS) combines more efficient cooling capacity with easier servicing and allows the machine to be operated in the most demanding environments.
  • Comfortable, efficient operator stations encourage high production with easy-to-reach controls, Cat Contour Series seats and excellent viewing area.
  • Cat planetary power shift transmissions feature large-diameter, high-capacity oil-cooled clutches.
  • Elevated sprockets isolate the final drives from ground impacts. Suspended undercarriages put more track on the ground for higher traction, less slippage, a smoother ride and longer machine life.
  • Large Cat Track-Type Tractor mainframes are heavy, strong and durable.
  • Major modular components are designed for excellent serviceability.
  • Cat dealers help machines operate longer with lower costs. They have the best parts availability and the best service capability.

Overview

Powertrain

Cooling System

The Advanced Modular Cooling System (AMOCS) combines more efficient cooling capacity with easier servicing. AMOCS allows the machine to be operated in the most demanding environments.

Operator Station

Comfortable, efficient operator stations encourage high production. Controls are low-effort and easy-to-reach. Caterpillar Contour Series seats provide proper support and automotive comfort. Front, side and rear views are exceptional.

Drivetrain

Undercarriage

Elevated sprockets move the final drives above the work area, isolating them from ground impacts. Suspended undercarriages put more track on the ground for higher traction and less slippage as well as absorbing shocks for a smoother ride and longer machine life.

Structures

Large Caterpillar Track-Type Tractor mainframes are heavy, strong and durable. Full box sections, steel castings and continuous rolled rails provide durable support to the suspended undercarriage, elevated final drives and other integral frame components.

Serviceability

Major modular components are designed for excellent serviceability allowing fast in-field component exchange.

Total Customer Support

Cat dealer services help machines operate longer with lower costs. Cat dealers offer a wide range of services under a Customer Support Agreement when equipment is purchased. Dealers will assist in choosing a plan that can cover everything from machine and attachment selection to replacement.
