ABSTRACT:
A delimber having a standard carriage and a delimbing boom, the delimbing boom slidably mounted through the carriage. A drive module is detachably connected to the carriage for use in moving the boom relative to the carriage. Two different types of booms and up to three different drive modules, each with a different drive, can be provided. The boom and module selected to give the operating characteristics desired by the operator are connected to the carriage. Drive transfer members, in the form of cable or chain drives, are connected between the selected drive module and the selected boom. The module carries a variable displacement hydraulic motor. The motor is connected by a gear box to the drive transfer member. The variable displacement motor can be used on a delimber that does not employ a detachable drive module. On delimbers using cable drives, at least one end of each cable is connected to the delimber with a hydraulic tensioner.
