Komatsu America Corp. Forestry Division announces the new high capacity C144 Harvesting Head, the second model in its new C-series family of “carry-style” heads (the C93 was the first). It is available installed on Komatsu 931.1 and 941.1 Harvesters, and can be installed on other carriers as a loose head.
The C144 features a new robust frame design for improved durability and reliability, and a new swing damping system for more responsive head control. The 40º rearward tilt angle provides fast feeding performance and reduces head frame stress when harvesting and/or reaching on downhill slopes. The feed system is completely new utilizing four hydraulic motors and four driven rollers. The standard single belly roller is now supplemented by an additional feed roller located in the feed path.
The C144 is equipped with two upper and two lower hydraulically controlled delimbing knives, and a fixed vertical top knife. The upper knives are specially designed to handle trees with tough limbs, such as lodgepole pine. The leading right upper knife has a ramped cutting edge to assist in cutting larger branches.
The new Constant Cut™ saw control system features a 32.5” (825 mm) saw bar that includes a new 19cc saw motor with an integrated valve to deliver precise control of saw hydraulic flow and pressure. This continuous management of flow and pressure allows the chain speed to be maintained at a constant 130 ft/sec (40 m/sec) throughout the entire cutting cycle. Along with automatic chain tensioning and automatic EcoOiler™ chain oiling this system results in faster cutting performance and reduced fuel consumption.
