Winches

Proven heavy-duty winch design works with updated electro-hydraulic control for more precise implement control. Boom and hook winches 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 removal and easy field service. Interchangeable parts between hook and boom winch assemblies help reduce cost and downtime. The winch profile is compact and enhances visibility.

Counterweight

New counterweight profile adds weight where you need it most to provide you the needed lift capacity for your application. Segments are contoured to help lower the machine center of gravity and are extended hydraulically for improved load balance and clearance. An electronic counterweight kickout switch has been added to limit the retraction of the extendable counterweight to the correct, retracted position.

Boom

The lightweight, 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. New PL83 now utilizes common 7.31 m (24 ft) and 8.53 m (28 ft) booms.

Blocks and Hook

Short profile block set enhances visibility to the work area and helps maximize the working range 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 mounted to the front of the machine allows for convenient storage of the block set during transport.

Pinned Pipelayer Frame Structure

Heavy duty pipelayer frame structures are designed to be easily pinned together to provide robust strength and durability in addition to improved serviceability.

Pipelayer Control

Implement joystick places all Pipelayer implement controls and functionality into one hand. Low-effort, ergonomically designed and positioned control handle allows simultaneous, precise positioning of the load line, boom, and extendible counterweight.

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

• Thumb rocker controls the counterweight extension and retraction.

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

• Quick drop activation.

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

Quick Drop Control

Quick drop control, when pushed downward, will allow the load on the hook line to fall freely to the ground. This control activation is to be used only in emergency situations, where the load must be quickly released.

Dual Brake Pedal Controls

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

Differential Steering Control

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

Structure

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.

Undercarriage

The PL83 Pipelayer 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.

Engine and Power Train

Engine

A Cat C15 ACERT engine provides the power and reliability you need to get the job done. Efficient use of Diesel Exhaust Fluid (DEF) improves overall fluid and fuel efficiency in Tier 4 Final/Stage IV engines.

Differential Steering

Differential steering maintains full power to both tracks for best-in-class turning, even with a loaded boom. When one track speeds up, the other slows down an equal amount, so you have better maneuverability in tight areas of operation. You also are equipped with dual brake pedal controls to provide additional maneuverability and steering control, especially in slope applications. The machine brakes are electronically actuated and hydraulically applied.

Emissions Technology

Emissions reduction technology on the PL83 is designed to be transparent, with no action required from the operator. Regeneration runs automatically in the background while you work.

Aftertreatment Technologies

Caterpillar designed Tier 4 Interim/Stage IIIB products with Tier 4 Final/Stage IV standards in mind for regions with Tier 4 Final/EU Stage IV emission standards requirements. To meet the additional 80% reduction in NOx emissions required by U.S. EPA Tier 4 Final/EU Stage IV emission standards, Caterpillar engineers added Selective Catalytic Reduction (SCR) to the already proven aftertreatment solution.

Diesel Exhaust Fluid

In regions requiring Tier 4 Final/EU Stage IV emission standards, the Selective Catalytic Reduction utilizes Diesel Exhaust Fluid (DEF) which can be conveniently refilled when you refuel. A gauge on the dash displays your fluid level. When the machine is turned off, a pump will automatically purge the DEF lines to help prevent the fluid from freezing in the lines and pump in colder environments. A symbol on the dash and a light/symbol on the left fender service center indicate when the purge is complete and that it is safe to turn off the electrical disconnect. If the engine/aftertreatment temperatures are high, a delayed engine shutdown will activate automatically to cool the machine and then purge the lines. For complete aftertreatment information, please refer to your machine's Operation and Maintenance Manual.
