Abstract

Described herein is an axial-drive felling head for restraining, cutting and manipulating trees.
The felling head comprises a holder connected to a manipulator arm, or crane, of a logging vehicle.
At least partially housed in either a frame or the holder is a motor for rotating the frame coaxially about the axis of rotation of a drive shaft of the motor. The frame is preferably disposed with arms for gripping and a saw for cutting. Advantageously, the felling head further comprises a transmission, preferably a gearbox, for augmenting the torque produced by the motor. The gearbox, which is preferably of planetary type, is at least partially housed in either the frame or the holder.
Since the drive shaft is coaxial with the axis of rotation of the frame, the size and complexity of the transmission is thus minimized.
