Crawler Tractors and Pipelayers (Sidebooms): Equipment Spotlight

January 2013, Vol. 68, No. 1
The Volvo PL3005 pipelayer.

Case
The Case 650L crawler dozer delivers 74 net hp through a proven, four-cylinder, 4.5-liter Case Family IV engine. Operating weights range from 16,250 to 17,550 pounds. Low operating height allows the 650L to work around low overhangs, while its lighter weight is ideal for work in soft soil conditions. The short track means easier turning and maneuverability on the job site. The compact size also makes the crawler dozer easy to transport from job to job. 866-54CASE6, casece.com

The new PL83, replacing the 583T, has a rated lifting capacity of 160,000 pounds — a 14 percent increase over the previous model. The new PL87, replacing both 587T and 587R, has a rated lifting capacity of 214,000 pounds, for a 6 percent boost in lifting capacity. Both models use the Cat C15 ACERT engine, with a net hp rating of 310 hp in the PL83 and 366 hp in the PL87. Both retain the field-proven Cat drive train, including a rugged 3F/3R powershift transmission, high-efficiency torque divider, elevated final drives and the exclusive Cat differential steering system. Boom choices for the PL83 and PL87 include 24-foot and 28-foot 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. cat.com/requestCatinfo
