Crawler Tractors and Pipelayers (Sidebooms): Equipment Spotlight
Pipelayers and crawler tractors from John Deere, Volvo CE, Pipeline Machinery, Case, Midwestern Manufacturing Company and Caterpillar.
The John Deere 850K crawler dozer features a new Interim Tier 4 engine, duel-patch hydrostatics and an outside dozer blade. Viscous cab mounts reduce noise to the operator’s ear by 45 percent. The John Deere PowerTech 6.8-L IT4 diesel provides either 187 hp or 205 hp at 1,800 rpm, and provides better low-end performance and quicker recovery when operating in the 1,500-1,800-rpm range. An outside dozer blade has a three-hole blade pitch with screw-type fine-tune adjustment for infinite settings and sloped cross-members provide lateral strength and superior visibility to the rear of the blade. Its raised position allows back-dragging. 309.765.1859, johndeere.com
The ability to swing 360 degrees allows the PL3005 pipelayer to handle large, heavy pipes with ease and place them anywhere around the machine. The patented excavator-based design of the PL3005 allows the machine to swap booms and convert into a standard excavator if needed. The high ground clearance of the undercarriage allows for operation in rugged conditions and visibility has been improved through standard fit rear and side view cameras. 828.650.2000, volvo.com
Pipeline Machinery Int’l.
The PL61 Pipelayer provides 40,000 pounds of lift-capacity. The PL61 features a Cat C6.6 ACERT engine, closed-loop hydrostatic drive system, oval-track SystemOne undercarriage and an electronically enhanced operator station. The pipelayer also maintains hydrostatic draw-works, two-speed load line and extendible counterweight. The 18-foot boom is constructed of high-tensile-strength steel, allowing a robust box-section design that is durable, yet lightweight to optimize payload capacity. The hook and cable-controlled boom are raised and lowered by independent hydraulic winches designed for smooth operation and infinite speed adjustment through their working range. Two-speed operation of the load-line winch provides high speeds for overall productivity, but lower speeds for precise positioning. plmcat.com
