Benefits and Features

The latest PL72 pipelayer offers operators added comforts like a quieter cab, adjustable armrests and heated/ventilated seat options. A seat belt indicator light helps remind you to work more safely.

  • A new Rollover Protection Structure (ROPS) provides added operator protection for open or enclosed operator stations.
  • A durable access ladder aids with access/egress to the operator station, and can be removed to minimize the machine shipping envelope. The new ladder system also features a grated top step, to provide added visibility to the trench.
  • Additional mirrors further enhance the operator's visibility around the machine.
  • Ergonomically designed seat is positioned for enhanced visibility to the working area and for convenient access to the machine control lever, switches and pedals.
  • LCD Dash Display provides added machine diagnostics to the operator, in addition to allowing operators to create a personalized profile and operational settings.
  • New HVAC system provides heat from ducting and dash vents to the operator for Open Cab (OROPS).

The new, optional enclosed cab is designed by Caterpillar specifically for demanding pipeline applications. The cab height meets shipping requirements and may be shipped by truck without removing the cab and Rollover Protective Structure (ROPS). The cab is fully sealed, filtered, and pressurized for harsh environments.

Glass area is maximized and visibility improved for better sight lines around the machine and to the trench. A large skylight window with sliding shade has been incorporated to provide a clear view from the seat to the boom and blocks.

1) Increment/decrement buttons on the implement handle provide continuous adjustable throttle.

2) Thumb rocker controls the counterweight extension and retraction.

3) Joystick pushed forward lowers the hook and joystick rearward raises the hook. Joystick left lowers the boom and joystick right raises the boom.

4) Quick drop activation.

5) Ergonomically positioned machine control switch panel provides easy access to the multiple switch functions of the machine.

The PL72 features a non-suspended, Cat elevated sprocket undercarriage. Track roller frame length remains extended, with rear idler positioned downward, resulting in more track on the ground to enhance machine stability, especially in slope applications.

Undercarriage components are built for long life and ease of serviceability. Rollers and idlers feature Duo-Cone™ seals to help prevent oil loss and dirt entry into the system. Tubular roller frame design resist bending and twisting, with added reinforcement where operating loads and stresses are highest. Cat Tough Steel sprocket segments are precision machined after heat treat for proper fit. Segments can be removed or replaced without breaking the track.

Pipelayer track is designed for high-impact and high load applications. The Positive Pin Retention Sealed and Lubricated Track is an exclusive Caterpillar design that locks the link to the pin for enhanced service life. Track shoes help optimize the machine for performance in demanding underfoot conditions.

The Pipelayer mainframe is engineered to handle the most demanding applications. The purpose built pipelayer mainframe is built to absorb high impact shock loads and twisting forces, and full box section frame rails are designed to keep components rigidly aligned. Heavy steel casting of the main case and pinned Ebar provide machine strength and durability. Top and bottom rails are continuous rolled sections, with no machining, that help provide superior mainframe durability. The final drives are elevated well above the ground level work area to protect them from impact loads, abrasion, and contaminants. Caterpillar uses robotic welding techniques in the assembly and manufacturing of the case and frames. The deep penetration and consistency of robotic welding ensures quality for a long, durable life.

A Cat C9.3 ACERT engine provides the power and reliability you need to get the job done. Improved fuel efficiency and efficient use of Diesel Exhaust Fluid (DEF) gives you excellent overall fluid efficiency.

Emissions reduction technology on the PL72 is designed to be transparent, with no action required from the operator. Regeneration runs automatically in the background while you work.

  • The PL72 meets Tier 4 Final/Stage IV or Tier 3/Stage IIIA equivalent emission standards.
  • Efficient use of Diesel Exhaust Fluid (DEF) improves overall fluid and fuel efficiency, for Tier 4 Final/Stage IV models only.
  • Longer service intervals help reduce parts and fluid consumption.
  • Major components are built to be rebuilt, eliminating waste and saving money by giving your machine a second – and even third – life.

Like all Cat machines, the PL72 is designed to allow you to get routine service done quickly and efficiently so you can get to work. The PL72 offers full left-side engine serviceability, including fill tube, dipstick, air cleaner, fuel filters, oil filter and coolant level check. Easy open engine enclosure doors allow you to maintain three points of contact for added safety. High speed oil change is standard and makes servicing even faster. Hydraulic and Power train filters and fuel tank drain are located at the rear of the machine and are serviceable from ground level.

Pressure taps are placed within the hydraulic system to allow for quick monitoring.

Major components like the engine, transmission, and final drives are modular so they can be more quickly removed for service, saving you cost and downtime.

The radiator, Air to Air Aftercooler (ATAAC) and hydraulic oil cooler are packaged into a single plane, making cleanout easier. Durable aluminum bar plate construction gives you superior heat transfer and corrosion resistance. Six fins per inch core allow debris to pass through and help reduce plugging. In cooler conditions, the Zero Speed Hydraulic fan will remain off until component temperatures require cooling, at which time the fan will begin to operate. Each pipelayer is equipped with reversing fan configuration as well.

Ecology Drains provide a convenient method for draining fluids that saves time and helps prevent spills. They are included on the radiator (coolant) hydraulic tank, engine, transmission, and mainframe case.

Cat dealers excel at providing parts availability and equipment service to even the most remote areas.

With more than 10,000 service technicians employed in over 3,000 Cat dealer locations around the world, Cat parts and service resources and capabilities are beyond compare.

  • Manage costs with preventive maintenance programs like Custom Track Service, S·O·SSM analysis, and guaranteed maintenance contracts.
  • Stay productive with best-in-class parts availability. Cat dealers can even help you with operator training to help you boost your profits.

And when it's time for machine replacement, your Cat dealer can help you save even more with Genuine Cat Reman parts. Receive the same warranty and reliability as new products at cost savings of 40 to 70 percent for power train and hydraulic components.

  • Convenient steps, handles and guardrail provide safe access/egress.
  • New seat belt indicator registers a fault code through Product Link if the operator fails to buckle up, helping to improve job site safety.
  • Electronic fluid level verification at startup for coolant, power train, engine oil and DEF means you can make fewer trips up and down from the operator station.
  • A standard operator presence detection system allows the machine to idle when the operator is not seated, but locks out the power train to avoid unintentional movement.
  • An optional rear vision camera is also available to further enhance visibility around the machine.
