HOW IT WORKS
speed of sound through wood provides a direct measure of stiffness
Extract structural logs from non-structural stands
Cut logs to right length knowing stiffness, streamline operation, OSH
Log segregation within stand can provide significant financial benefit
Stiffness of green wood in logs and stems is variable dependent on species, site, genetics and silviculture. Acoustic velocity measurement is used because it is a direct measure of wood stiffness.
The biggest destruction of value after 30 years of forest nurture is at the point of log making when quality decisions are made without measuring the wood strength.
HITMAN HM200 is applied on the end of the log, and is used by many logging crews around the world to measure wood stiffness in motor-manual logging operations - a much larger, automated version of this technology the HITMAN LG640 is installed in saw mills.
The HITMAN ST300, is used to measure wood stiffness in standing trees for pre-harvest assessment. Effectively, the HITMAN PH330 processor head device takes the technology of the award winning HITMAN ST300 and integrates it into a harvester head to automate the wood quality measure into mechanical log making operations.
