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.
At the small end of Caterpillar’s line of pipe l yers, the PL61 offers 40,000 pounds of lift capacity and features the Cat C6.6 ACERT engine.
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.
The Volvo PL4608 and Volvo PL4611, with maximum tipping capacities of 80 and 110 metric tons, form the core of a new range of excavator-based pipe layers
