The Cat PL83 and PL87 pipelayers retain the basic design of their predecessors while answering customer needs for increased lift capacity, enhanced slope capability, ease of operation, performance and transportability.
The 310-hp PL83 replaces the 583T and has a rated lifting capacity of 160,000 lbs., a 14% increase. The 366-hp PL87 replaces both 587T and 587R, and has a rated lifting capacity of 214,000 lbs., a 6% increase. Both models use the C15 ACERT engine, as well as a Cat drivetrain, including a rugged 3F/3R powershift transmission, high-efficiency torque divider, elevated final drives and Cat differential steering system.
Boom choices include 24- and 28-ft. versions, each fabricated with high-tensile strength steel for durability to handle added payload. A new block-set design enhances sightlines to the pipe, and a new bolt-on block horn on the frame of the tractor's radiator guard secures the block for transport.
