![]() The new operator station features high-def touchscreen displays with scalable electronic architecture. RELATED: Cat dozers are undergoing a name change ![]() Delayed egress lighting allows the operator to exit an illuminated dozer, while access lighting is controlled from the cab or ground-level electrical centre. The cab door can now be mounted for either left- or right-side opening. Standard features built into the new D11 dozer offer improved access to the operator compartment. Technicians may also fill the auto lube system and change the coolant as well as hydraulic, engine and powertrain oil from the ground. The ground-level electrical centre provides access to the lockout control, engine shutdown switch, and switches for access ladder raise/lower and remote-control mode options. Improved serviceĪ 30 per cent larger engine oil sump capacity extends preventive maintenance intervals to 500 hours in challenging environments, giving customers more uptime. Improved reversing fan function delivers improved reverse airflow for radiator cleanout. Furthermore, it provides easier core cleanout. A new single-plane cooling system design better dissipates heat to maintain consistent operating temperatures, even in extreme heat. The Caterpillar C32 engine delivers 850 hp forward and 955 hp reverse for increased performance. Replaceable bearings on the ripper and blade pin boreholes and new push arm trunnion bearing inserts offer quick replacement and extend component life. The new D11 dozer also improves on the time-tested elevated sprocket undercarriage with a more robust track roller frame to extend component service life. The larger equalizer bar features an improved bearing design to increase reliability. When combined with the new, high-horsepower reverse function, the machine delivers 4 to 8 per cent more productivity while burning less fuel. ![]() As well, the new stator clutch torque divider provides improved drive train efficiency. The variable hydraulic pumps adjust output to meet demand, which saves energy, reduces heat generation and extends component life. ![]() The D11 dozer is also equipped with new load-sensing hydraulics and new drive train components that deliver up to 8 per cent greater fuel efficiency. The new Caterpillar D11 dozer is engineered with a redesigned main frame that delivers lower total cost of ownership over the life of the machine and engineered to be rebuilt multiple times. ![]()
