High performance Log Loader with Komatsu designed forestry attachments


Komatsu Fully Certified Forestry Cab

The ROPS/OPS/FOPS/TOPS/FOG/WCB/Oregon OSHA certified Komatsu Forestry cab provides a comfortable and quiet work environment so operators can maximize their productivity. The OPS certifed cab is specifically designed for forestry applicatiaons and gains strength from a reinforced framework. The operator platform is mounted on viscous damper mounts to isolate vibrations from cab floor.

Komatsu Live Heel Boom

Komatsu designed and built 38' reach live heel logging boom has Komatsu built boom, arm, heel and hydraulic cylinders.

Komatsu Forestry Undercarriage

Large PC290 class track component and final drives provide 56,244 lbf drawbar pull for excellent slope climbing performance and maneuverability.  Forestry high and wide car body with 28" ground clearance has a heavy duty swivel guard, full length bottom roller support rock guards and reinforced idler with large recoil spring.  Wide 9'7" gauge improves over the side life capacity.

Komatsu SAA6D107E-2 Engine

Powerful Komatsu SAA6D107E-2 engine provides a net output of 177kW (132 kW) is EPA Tier 4 interim and EU stage 3B emissions certified. Forestry modifications include insulation with heat shields for the diesel particulate filter and debris screens on engine compartment air flow openings.
