Tackling thick forests can be a challenging task for logging companies. Komatsu’s C144 harvesting head makes it possible to work efficiently and productively in even the most demanding harvesting environments.
C144 Key Features  C144 Quick Specs
The four-wheel-drive (4WD) feed system features an extra roller that provides greater feed force with a rate of up to 5 m/s and Constant Cut technology to ensure chain speeds deliver high harvesting capacity. These elements allow operators to fell, limb and cut trees simultaneously, boosting performance output. The 1,410-kg harvesting head can also be outfitted with multi-tree-handling capabilities.

The C144 is equipped with an 82.5 cm saw bar, and production can be further enhanced with the addition of an optional 90 cm saw bar for increased productivity and broader application areas. The C144 has a theoretical maximum fell/cut diameter of 750 mm and a delimbing diameter maximum of 510 mm.
“Customers who work with this head are very surprised at the precision, high productivity and low repair costs,”
said Patrice Ouimet, Manager, Forestry Division at SMS Equipment. “The first time I saw this harvesting head working, I was impressed with its performance.”

Operators can cut with confidence thanks to patented length-measuring technology that ensures accuracy via a non-contact signal transmission.

The C144 is recommended for tree diameters between 200 and 500 mm, and its overall possible work range is between 50 and 550 mm.

Delimbing is performed with four hydraulic knives. A pair of forward knives are positioned to more efficiently process challenging trees.  The front knives have an opening maximum of 660 mm, with the rear knives boasting a maximum opening of 800 mm.
