Cat® has welcomed its new pipelayers. The Cat PL72, PL83 and PL87 pipelayers feature an integrated, all-Cat power train with differential steering and an electronically controlled hydraulic system that places total control of lifting functions into one single joystick.
The new pipelayers have been designed to meet the demands of the pipeline industry – for increased lift capacity, enhanced slope capability, ease of operation, performance and transportability.
Independent variable speed winches for the boom and hook allow for precise control and the enhanced counterweight system ensures a low center of gravity for optimum performance.
In addition, Cat’s new roll-over protection structure (ROPS) provides added safety for both open and enclosed operator stations. Cat’s new, purpose-built pipelayer cab is now pressurised and incorporates comfort and convenience features.
The compact-profile winch assemblies feature oil-disc brakes to provide smooth operation and positive retention of boom and hook positions; the modular, pin-on design of the winches allows fast service in the field.
The lightweight, durable boom features high tensile strength steel construction and a narrow design that enhances visibility to the work area.
The short-profile block set enhances visibility to the work area and extends the working range of the boom. Heavy-lifting components include hook and boom blocks with sleeve bearings, forged hook with latch, ductile iron sheaves and heavy duty frame structures pinned together for strength and durability.
The pipelayers offer added operator comfort features, such as a quieter cab, adjustable armrests and heated/ventilated seat options. A dash-mounted LCD display provides on-board diagnostic information for the operator, allows operators to create individual profiles and operational settings and provides access to multiple switch-controlled functions.
The cab is fully sealed and supplied with filtered, pressurised air for a clean environment. Expansive glass surfaces allow unhindered visibility around the machine and into the trench, and a large skylight with sliding shade provides a clear view to the boom and block.
The new models are equipped to accept a load monitor indicator (LMI), with new hydraulic circuitry, integrated mounting hardware and ready-mount power supply to facilitate installation.
For added safety, a wide angle rearview camera enhances visibility to the work area and 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.
To facilitate routine maintenance, hydraulic pressure taps allow quick pressure monitoring, and ecology drains for the radiator, hydraulic tank, engine, transmission and main case add to service convenience and prevent spills.
