Integrated, robust components


New heavy-duty winch design works with updated machine hydraulics for greater productivity. Boom and hook draw works are driven by independent hydraulic winches. Oil-disc brakes provide smooth operation and positive retention of boom and hook positions. A modular, pin-on design allows for fast replacement and easy field service. Interchangeable parts between hook and boom winch assemblies help reduce cost and downtime. The winch profile has been reduced to enhance visibility and meet critical transport requirements for rail shipment.


New counterweight profile adds more counterweight, increasing lift capacity. Segments are contoured to provide a low center of gravity and enhanced visibility to the front and side. The counterweight is extended hydraulically for improved load balance and clearance. Segments are splined for ease of assembly and disassembly. The PL83 has a rated lift capacity of 72 575 kg (160,000 lb).


The light weight, durable boom features high tensile strength steel construction for narrow structures and maximum visibility to the work area. Replaceable boom-mount bearings aid serviceability and long life.

Blocks and Hook

Updated block set profile enhances visibility to the pipe and helps take advantage of the full length of the boom. The heavy-lifting components include hook and boom blocks with sleeve bearings, a forged hook with latch and serviceable handle, and ductile iron sheaves. A bolt-on block horn has been added to the front of the machine for convenient storage of the block set during transport.


A robust drawbar tows a wide range of attachments for maximum versatility.

Operator Station

Designed for Productive Comfort

Caterpillar designs operator stations for maximum productivity. Operator comfort features and excellent visibility all around the machine help operators work more efficiently and contribute to job site safety. Customers may choose an Open Cab (OROPS), an Enclosed Cab with single pane glass, or an Arctic Cab with Dual Pane glass.
  • A Roll Over Protection Structure (ROPS) provides added operator protection with an open or enclosed cab.
  • A more durable access ladder design aids access/egress to the operator station, and can be removed to minimize the machine’s shipping envelope.
  • Additional mirrors further enhance the operator’s visibility all around the machine.
  • Ergonomically designed seat is positioned for enhanced visibility to the trench and for convenient access to key operator control levers and pedals.
  • Monitoring system provides instant feedback on the condition of operating systems and records performance data for diagnostics and to help manage undercarriage wear. The system also features a digital and gauge-type tachometer.
  • 12-volt outlets power devices like cell phones and laptop computers.

Implement and Steering Controls

Ergonomically Designed for Ease of Operation

Pipelayer Control

Right joystick places all of the boom, hook and counterweight function control in one hand. Low-effort, ergonomically designed control handle allows simultaneous, precise positioning of the load line and boom. 1) Increment/decrement buttons on pipelayer control handle provide continuous adjustable throttle. 2) Thumb rocker controls the counterweight functions. 3) Joystick forward lowers the hook and joystick back raises the hook. Joystick left lowers the boom and joystick right raises the boom. 4) Quick drop control. 5) Rocker switch allows the operator to increase/decrease engine speed to a set level with the touch of a button.

Quick Drop Control

The new quick drop control, when pushed, will allow the load on the hook to free fall to the ground. This control is to be used only in emergency situations where the load must be released immediately.

Dual Brake Pedal Controls

Dual brake pedal controls provide enhanced maneuverability and steering control, especially in slope applications. Brakes are spring applied and hydraulically actuated.

PL83 Steering Control

Dual-twist tiller control with standard differential steering controls direction and degree of turns, forward/reverse shifting, and gear selection in a single control handle. One hand steering enhances operator comfort.

Enclosed Cab

Designed with Pipeline Productivity in Mind

The optional enclosed cab is designed by Caterpillar specifically for demanding pipeline applications. The cab is designed to work with the Rollover Protective Structure (ROPS), and is fully insulated with a heater. Air conditioning is available as an option. Glass area is maximized for excellent sight lines around the machine and to the trench to aid productivity and enhance job site safety. A skylight window provides a view to the boom and upper block. The cab includes eight additional halogen lights: three facing forward, two to the rear, two to the boom side and one to the winch side. Wipers provide a clearer view during inclement weather.

Arctic Arrangement

An arctic arrangement equips the pipelayer for optimal performance in arctic conditions. The Arctic Cab has many of the same operator comfort features as the enclosed cab, but adds dual pane windows for cold weather environments. The arrangement also incorporates fluids, final drive and roller seals, and batteries designed to perform in severe cold weather environments.

Engine and Power Train

Powerful Efficiency


The Cat C15 engine with ACERT™ Technology provides the large displacement and high torque rise for the power needed on challenging jobs. Matched to the high-efficiency torque divider and electronically controlled power shift transmission, the C15 ACERT engine will provide years of dependable service.

Constant Net Horsepower

Constant net horsepower maintains high standards of performance and response. The engine automatically adjusts to maintain power output and conversely lowers output when demands are low. This provides significant fuel savings in cooler climates and during long engine idle times typical of pipeline applications.

Planetary Power Shift Transmission

The planetary power shift transmission offers smooth shifting and quick speed and directional changes for maximum productivity. With three speeds forward and three speeds reverse, the transmission utilizes large diameter, high capacity, oil-cooled clutches for long life. An oil-to-water cooler facilitates maximum cooling capacity, and forced oil flow lubricates and cools clutch packs for long life.

PL83 Differential Steering System

A planetary differential turns the machine by speeding up one track and slowing the other, while maintaining full power to both. This contributes to superior maneuverability, as well as enhanced slope capability. Differential steering also aids performance in soft underfoot conditions because both tracks are powered during turns. The low effort steering tiller aids ease of operation.


Underlying Strength

The Pipelayer main frame is engineered to handle the most demanding applications. The 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 castings add strength to the main case, center saddle and front cross member for outstanding durability. Top and bottom rails are continuous rolled sections, with no machining or welding, to 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 of the case and frames. The deep penetration and consistency of robotic welding insures quality for long life and durability.


Engineered for Performance

The PL83 features a non-suspended, Cat elevated sprocket undercarriage. Track roller frame length has been increased by 128 mm (5.03 in), and the rear idler has been moved down and rearward, resulting in more track on the ground to enhance machine stability, especially on steep slopes. 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. Tubular roller frames resist bending and twisting, with added reinforcement where operating loads 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 PL83 is equipped with 762 mm (30 in) medium service track shoes with sealed and lubricated track (48 sections).
