Power Train

Perfectly matched power train. From the powerful and fuel efficient 3306 DIT engine to the durable power shift transmission, all Caterpillar components work together to deliver responsive power when you need it.


Cat 3306 engine. Caterpillar 3306 engine performs at full-rated net power of 171 kW (230 hp) at 2100 rpm with high torque rise of 36%. High horsepower, combined with high torque rise, give the 572R the durability needed on the challenging jobs. Plus, this engine meets all the latest emission regulations around the world.


Turbocharged and aftercooled 3306 diesel engine delivers plenty of power for quick response, big loads and improves response and performance at low to medium engine speeds.

Long Life

Large displacement, high torque rise and low rpm rating for low stress, long life.


High torque rise offers superior lugging capabilities - keep moving through tough spots without downshifting.


Good weight-to-horsepower ratio - faster loading, bigger loads, shorter cycle times.

Fuel System

Direct unit injection fuel system eliminates external high pressure fuel lines and provides excellent control of injection timing with individually metered, high-pressure, direct-injection of fuel. Result is improved engine response and reliability plus low fuel consumption and emissions.


Resilient engine mounting for quieter operation and less vibration.

Advanced Modular cooling system (AMOCS)

Advanced Modular cooling system (AMOCS) utilizes an exclusive two pass cooling system and increased cooling surface area to provide a more efficient heat transfer system than conventional systems.

Drive Train

Drivetrain components are matched and balanced to deliver exceptional performance and durability.

Torque Divider

Torque Divider. A single-stage torque converter with output torque divider sends 70% of the engine torque through the converter, 30% through a direct drive shaft for greater driveline efficiency and higher torque multiplication.

Torque Converter

Torque converter responds to changing load conditions by providing torque multiplication for increased drawbar pull while protecting the drive train from shock loads.

Converter Design

The torque converter shields the driveline from sudden torque shocks and vibration.


Planetary Power Shift Transmission has 3-speeds forward and 3-speeds reverse and utilizes large diameter, high-capacity, oil-cooled clutches.
  • Modulation system permits fast speed and direction changes.
  • Modular transmission and bevel gear slide into rear case for servicing ease, even with ripper installed.
  • Oil-to-water cooler for maximum cooling capacity.
  • Forced oil flow lubricates and cools clutch packs to provide maximum clutch life.

Planetary Design

Proven planetary design delivers fast, smooth speed changes while distributing loads over multiple gears for long life. Perimeter-mounted clutches provide superior heat dissipation and a large contact area for long service life.

Clutches and Brakes

Separated clutches and brakes. Oil-cooled, hydraulically actuated multiple-disc clutches and brakes for smooth, precise turns.

Final Drives

Final drives. Precision, high load capacity gears and bearings give long-lasting performance and durability.


Mainframe is designed and built for durability using the latest technology in engineering and manufacturing. It provides solid support and perfect alignment for major components.


High strength steel mainframe. The 572R mainframe absorbs high impact shock loads and twisting forces.


Structural testing analysis is used to verify and ensure integrity of the mainframe.


Robotic welding provides deep penetration and consistency for long life.

Roller Frames

Roller frames are tubular, to resist bending and twisting, with reinforcement where operating stresses are the highest.
  • Non-oscillating roller frames for greater stability in pipelaying applications.
  • The recoil system is sealed and lubricated.
  • Improved pipelayer structure mounting.


The elevated sprocket moves the final drives above the work area, isolating them from ground impact for long power train component life.

Final Drives

Final drives and associated power train components are raised above the work area, isolating them from the ground-induced impact loads, as well as pipelayer loads, extending power train component life.


Sprocket position keeps sprocket teeth, bushings and final drives away from the abrasive materials and moisture, resulting in longer final drive gear and seal life.

High Flange

High flange improved track rollers (optional) combined with center or full length roller guards attachments greatly improved track guiding for demanding side slope conditions.

Track Shoes

Track shoes are 660 mm (26”) single grouser shoes made from heat-treated, rolled steel for added strength. Long track frame and wide gauge enhance track contact area, providing a very stable working base.

Operator’s Station

Ergonomically designed for maximum productivity and comfort. Controls are intuitive, low-effort and easy to reach, viewing area is excellent, instrument panel is easy to read and informative, and storage space has been increased.


Operator’s station provides excellent comfort and convenience. The new counterweight design provides improved viewing area from the machine.


Pipelayer steering clutch levers are easy-to-reach, low-effort controls. They are independently actuated for sure, precise steering.


The seat is ergonomically designed and fully adjustable for maximum comfort. The seat cushion reduces the pressure on the lower back and thighs while allowing unrestricted arm and leg movement.

Instrument Panel

Instrument panel is the Electronic Monitoring System (EMS) for monitoring critical machine functions. There is also a gauge group displaying fuel level, coolant, and power train oil temperatures.


Separated brakes are independent of the steering clutch function to give the machine precise steering control.


Pipelayer controls are low effort and allow simultaneous, precise positioning of the load line and boom.

Load Line Speed

Load line speed range is controlled by a push-pull knob that allows the operator to select high or low.


Counterweight control adjusts the position of the counterweight for added machine stability.

Auto Shifting

Automatic shifting features. Bi-Directional Auto shift allows the operator to pre-select a forward and reverse gear for directional changes.

Auto Kickdown

Auto-kickdown automatically downshifts the transmission when the engine lugs down to a predetermined RPM level.

Operator’s Station Access

Simplified entry by adding a ladder on the right rear side of the machine.


Fully hydraulic load line and boom winches provide excellent speed capability. Counterweight and frame design provides excellent stability while offering increased viewing area.

Winch and Boom

  • Boom and hook drawworks are driven by independent hydraulic winches.
  • Oil-disc brakes provide smooth operation, positive retention of boom and hook positions.
  • Modular design allows fast replacement, easy field service and testing.
  • Infinitely variable speed controls for both boom and hook allow precise control.
  • Tubular, cast-steel boom is rugged, delivers better fatigue life.
