Komatsu C164 is a brand-new model in the range of C heads and a perfect match for the Komatsu 951 harvester. The robust head is specially designed to handle large trees, big root flares and rough limbs. Still, it has a design that makes it smooth and easy to handle. The C164 design is inspired by the features of other C models, but it is a completely new head where many parts are optimised for the size and application of the head.
Constant Cut, the saw motor control that ensures that the head has a constant and efficient saw motor speed throughout the complete cutting cycle, is further developed for C164 to handle long saw bars and broad stems. The saw bar position is designed for optimal felling performance and the position of the saw bar is new compared to other C heads. This gives a better felling cut in the direction of the head, which in turn gives the saw bar better longevity whilst also reducing the risk of log splitting. For increased durability and service life the chain tensioning of the saw bar has been improved, the saw bar mount has a more robust design, stronger saw bar clamp and increased bolt dimension to hold the saw bar.
The rotator has a stronger and more robust design as well as a new hydraulic motor and bigger slew bearings to cope with this type of demanding logging operations.
To make the head more fuel efficient, the C164 also has a new type of hydraulic control valve that can handle a high flow, which reduces energy losses.
The C164 is a “carry style” head, where the stem is carried by the feed wheels and the delimbing knives are mainly used for delimbing the stem. The head’s feed system allows good contact between head and stem, which reduces the clamping pressure and makes the feeding procedure energy efficient. Komatsu C164 comes with the option of two different feed roller motors. The bigger motor is standard and gives a high traction force which improves the productivity of the head. The smaller motor is optional and gives a more aggressive feeding start, but with less force than with the bigger motor.
