Apparatus for cutting and/or handling material to be cut

A device for cutting and/or handling trees, comprising:

• a pivotable boom arm to which a gripping or cutting head is attached, wherein the boom arm comprises:
• a rotatable crane pillar,
• a first boom which is pivotably mounted on the rotatable crane pillar about a first pivot axis,
• a second boom having a first end region pivotably mounted on the first boom about a second pivot axis,
• wherein the first and second pivot axes are arranged parallel to one another and perpendicular to longitudinal axes of the first and second booms, and, at a second end region of the second boom remote from the first end region, the gripping or cutting head is pivotably mounted on the second boom about a third pivot axis, and
• wherein the second boom comprises a first boom part having the first end region, and a second boom part having the second end region, which is a telescopic boom which can be extended in a longitudinal direction of the second boom part, wherein the second boom part is fastened or integrally formed on the first boom part to the side of the first boom part, as seen in a longitudinal axial direction of the first boom part, and
• a controllable pivoting device is provided, by means of which the gripping or cutting head can be pivoted about the third pivot axis from a folded-out working position, in which the gripping or cutting head, as seen in a longitudinal axial direction of the second boom, is positioned in front of the second end region, into a folded-in storage position, in which the gripping or cutting head is arranged to a side of the second boom.
