摘要： In the present arrangement, a forest machine is controlled, which forest machine includes a body (2), a boom (3) in connection with the body (2) and a tool (4) at the end of the boom (3). A sensor (9) arrangement determines in advance the size of utilisable free space (11A, 11B) starting from the end of the boom (3). This determination consists of determining a direction and a length of the free space (11B). The operation of the tool (4) is allowed into the direction and for the length of the utilisable free space (11A, 11B) determined in advance.

摘要： A curved blade for a delimbing head operable to cut branches from a felled tree is disclosed. The curved blade comprises a cutting rim, at least one portion of which comprises a continuous flange defining a continuous cutting edge, as well as at least one row of ribs that are straight and parallel to each other, extending in the direction of at least one face of the cutting rim from the continuous flange. The continuous cutting edge of the blade having these straight parallel ribs reduces the lateral load of the continuous cutting edge during the operation of cutting branches from a felled tree.

摘要： The present invention relates generally to an improved tree processing system enabling efficient, reliable and accurate processing of harvested trees. The system includes a grabbing head having first grabbing arms and a delimbing head having second grabbing arms. The first and second grabbing arms are mounted on a boom system and can be activated to grab the tree stem of a harvested tree. When grabbed, the boom system can be selectively extended or retracted to effect delimbining of a felled tree. Each of the delimbing head and grabbing head includes saws allowing an operator to selectively activate one or both saws to cut a length of timber.

摘要： A cutting device includes a generally planar guide bar having a peripheral groove. An endless saw chain is disposed around the guide bar and includes links and connector elements joining the links to each other to form an endless chain loop. The links include drive links and consecutive tooth links connected to a same one of the drive links. Each tooth link includes a cutting tooth protruding from one side of the saw chain. Consecutive cutting teeth of the tooth links are arranged to alternate to right and left sides relative to a plane defined by the guide bar. The saw chain is operably circulated around the guide bar groove for cutting.

摘要： Embodiments described herein provide methods, apparatuses, and systems for moving, loading, and/or sorting logs. A log grapple may include opposing arm assemblies and independently positionable drive wheels disposed between the arms. The log grapple may be operable in a grapple mode, in which the arms are in a closed position and the drive wheels are in an open position, and a feed mode, in which the arms and the drive wheels are in closed positions. In feed mode, the first and second drive wheels may be rotated to drive the log through the arms. The log grapple may be further configured to delimb, measure, and/or cut logs in the feed mode. A log grapple may also include a measuring wheel assembly. Optionally, the measuring wheel assembly may include a hydraulic actuator configured to retract the measuring wheel and a gas spring configured to extend the measuring wheel.

摘要： Disclosed is a method and apparatus for chipping a tree utilizing a helicopter suspended chipping apparatus. The chipping apparatus comprises a frame having a bottom, which is suspendable from a support vehicle and includes a chipping rotor having a length extending along a substantially horizontal axis and a chipping surface. The chipping rotor is rotatably mounted in the frame such that a lowermost portion of the chipping surface is proximate to the bottom of said frame. The chipping apparatus further includes a drive motor operably connected to the chipping rotor for rotating the chipping rotor about the substantially horizontal axis. The chipping apparatus may be lowered onto a tree to be chipped by the helicopter so as to chip the tree proximate to ground level.
