2016 Caterpillar 545D

Building on Caterpillar's 40+ years' experience designing and manufacturing skidders, the Cat® D Series Wheel Skidder delivers more productivity at lower operating cost. Get more wood to the landing faster in a stable machine with a roomy, comfortable environment for the operator. Advanced hydraulics speed up multi-functioning and cycle times and give you more lift capacity. The D Series runs cool and is designed to keep debris from collecting inside the machine. Tilting cab and other access points cut the time needed for daily maintenance and servicing.

Features may include:

The Cat C7.1 ACERT™ engine is designed to deliver more power than ever before, while still achieving the highest levels of total fluid efficiency, reliability and durability.

The C7.1 ACERT engine meets U.S. EPA Tier 4 Final and EU Stage IV emission standards using a blend of technologies to optimize performance, whatever the conditions. The Selective Catalytic Reduction (SCR), Exhaust Gas Recirculation (EGR) and Diesel Oxidation Catalyst (DOC) systems effectively remove NOx gasses from the exhaust, while a fully passive, service-free Diesel Particulate Filter (DPF) removes soot and other particulates. All Cat C7.1 ACERT emissions technologies are designed to be transparent, so you are free to concentrate on the job at hand.

The High Pressure Common Rail Fuel System provides precise and efficient combustion, allowing for maximum performance improved fuel efficiency and enhanced reliability. Series turbochargers provide extra power when needed. The engine is designed for maximum uptime and reduced operating costs, with world-class support from the Cat dealer network.

Industry leading integration and engineering support is at the heart of everything we do. The Cat C7.1 ACERT engine is fine-tuned to work seamlessly with machine control systems, optimizing the engine for demanding work cycles.

With a durable design and long life, the C7.1 ACERT delivers better fuel economy, with minimized maintenance costs, while still providing the same great power and response you expect.

The high capacity cooling system and on-demand hydraulically driven reversing fan keep the machine running at the proper operating temperature, optimizing performance, durability and fuel efficiency. The system, designed to meet the cooling requirements of the 555D, is common to all models, boosting fuel efficiency and capacity in the smaller models.

Power to the ground is an advantage of the Cat D Series. The axles are designed specifically for the skidder application and the gear ratios cause the power to be generated in the axles reducing torque in the transmission and drivelines extending their life. Both drawbar performance and durability are improved.

The new hydraulic system gives the D Series more speed, increased multifunctioning capability and greater lift capacity. This efficient load sense system with variable displacement pump continually monitors hydraulic power requirements and provides power based on demand to save fuel.

Robust frames provide a solid foundation for a machine designed to provide long life. Every structure was engineered for durability and verified through lab and field tests.

Box-section construction was used in the arch and boom designs to transfer heavy loads efficiently into the main frames. The arch gate is integrated into the arch and comes with a bolt-on fairlead roller assembly for skidders ordered with a winch, or a bolt-on guard, for skidders not equipped with a winch.

The dual function arch and boom is available on all models while the single function arch is available on the 525D and 535D. The cable arch is available on all except the 555D.
