The PL4809D excavator-based pipelayer can lift 90 tons and can rotate 360 degrees.
Cat PL83 pipe layer replaces the 583T and has a rated lifting capacity of 160,000 pounds, a 14-percent increase. Cat PL87 replaces both the 587T and 587R and has a rated lifting capacity of 214,000 pounds, a 6-percent boost.
New Holland extended the versatility of its crawler dozers by fitting them for pipelaying with an optional 15-foot hydraulic sideboom.

Volvo challenges conventional pipe-layers — side booms on bulldozers — with its excavator-based PL4611 and PL4608 pipelayers. The 360-degree swing capability suggests significant pipe-handling advantages including keeping the operator facing the pipe, and Volvo claims better stability with wider track gauge and lower center of gravity.
