Pipeline Machinery Intl.

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. 713.939.0007,
