Abstract: The invention relates to a cutting device (1) of a mobile working machine, for cutting elongated objects (2), in particular piles (2), and for being connected to a mobile working machine, comprising a first gripping member (101) and a second gripping member (102), which gripping members (101,102) are pivotal around the same pivot axis (X), said gripping members (101,102) having gripping faces (101a,102a) delimiting from opposite sides a gripping gap (G) as viewed in direction of said pivot axis (X); and moving means (103) actuatable to move the gripping members (101,102) towards and away from each other; and cutting means (104) including a cutting unit (1040) for cutting an elongated object (2) placed in the gripping gap (G); wherein the gripping face (101a,102a) of each gripping member (101,102) is shaped to have a gripping recess (R) for receiving a side of the elongated object (2) placed in the gripping gap (G), the gripping recess (R) comprising: a bottom point (C0) via which a circle (Y1) passes, which c

Abstract: The invention relates to a device for cutting concrete piles. The device having a frame, gripping means connected to the frame and including at least two opposing gripping parts, which are movable at least closer to each other to form a closing grip around a pile and further away from each other to release the pile from the closing grip, and sawing means, which are arranged to perform a back and forth sawing movement on the two opposite sides of the pile moving along a horizontal guide rail attached to the frame and which is further arranged to turn towards the pile to be sawed and back around their rotational axis. The invention further relates to computer program means suitable for controlling a device according to the invention to perform a desired sawing profile in the concrete pile.

Abstract: A cutting device is disclosed for performing work actions to a pile, the cutting device having a body part for connecting the cutting device to a working machine. The cutting device can grip the pile using at least two opposite gripping parts to obtain a grip from different sides of the pile. A sawing device can perform a sawing action. The cutting device includes joint points of the opposite gripping parts, a distance between joint points, being alterable, and the gripping parts are moved by altering the distance between the joint points of the gripping parts to obtain desired contact areas between the gripping parts and the pile.

Abstract: A cutting device for cutting a pile, including a body part, for connecting the cutting device to a working machine and a gripper attached to the body part to drive the cutting device around the pile to be cut, the gripping means having at least two opposite gripping parts to obtain a grip from the pile and to release the gripper from the grips. The cutting device includes at least two sawing parts arranged to move to a sawing position and to a secure position, and the cutting device having a saw connected to the sawing parts to perform sawing operation when at least one sawing part is in the sawing position, and the cutting device includes elastic means to adapt to forces, which arises during sawing movement of the a saw. The saw is arranged to move during the sawing movement substantially horizontally to the pile being cut.
