Based on the Volvo excavator design, configuration and engineering, the Volvo PL4611 Pipelayer provides a 360-degree swing with full lifting performance and functionality at all radius positions – a function unattainable with conventional side-boom pipelayers. The Volvo PL has a wide gauge, lower center of gravity, and a lifting platform where the boom is mounted inboard of the track frame and closer to the machine’s centre line for extraordinary stability and much higher lift capacities – up to 29 percent higher – than conventional equipment. Lift capacities range from 20 metric tons to 150 metric tons, originating from a patented adaptation of Volvo excavator machines combined with modern lifting technology. Volvo Pipelayers also have significantly longer booms that offer higher hook height for better work positioning – or in working further away from the trench to avoid caving in side walls. Boom lengths range from 30 feet to 38 feet, depending on model size. The machine is powered by a Volvo D12D 329-hp EPA Tier 3 compliant engine engineered with the Volvo Advanced Combustion Technology (V-ACT) system to produce low emissions, better performance and productivity, and industry-leading fuel efficiency. It has a maximum tipping capacity of 242,500 pounds, a boom length of 30 feet, an operating weight of 150,220 pounds, and a lift capacity through 360-degree rotation of 155,000 pounds.
