  • Patent number: 9739026
    Abstract: Systems and methods for cutting piles wherein, for example, a pile cutting device is attached to the end of an articulated arm of an excavator, the pile cutting device having a set of grasping arms that hold the pile and a set of saw blades that are linearly advanced to cut the pile in a single stroke. The saw blades are offset so that the cutting paths of the blades overlap. The saw blades may be positioned at the ends of telescoping arms that are coupled to a linearly movable frame. A single hydraulic unit moves the frame along a central rail. The frame is coupled to one or more cables and pulleys so that the travel of the telescopic arms is twice that of the frame.
