Re-defining “in the woods” Chipping
BRUKS 805.2 STC
Labor costs to operate
Fuel costs
Maintenance costs to upkeep several machines
Transportation Cost to move several machines
To get a product that still needs more processing
Capital Investment to buy several machines
Current in woods Systems
A more economical process
Fewer machines = Lower costs
Producing a quality energy chip
A New Era in Harvesting Forest Residue
• A “one machine chipping system” to recover wood fiber left in forest
• A forwarder mounted chipper, flexible and mobile with integrated dumpable 27 cubic yard chip bin
• Great for production of uniform quality energy chips • The most economical way to harvest woody biomass
with lower labor costs, lower fuel consumption, less equipment, less maintenance.
Solving Chip Handling Issues
