Studi kasus singkat oleh Tibor Horvath dengan Uji Tarik Fakopp
Pohon itu berdiri di taman pinggiran kota. Kondisi menunjukkan bahwa pohon itu harus ditebang. Penebangan tersebut diubah menjadi serangkaian 6 percobaan tentang bagaimana pohon kehilangan stabilitasnya karena “kehilangan” akar utamanya. Faktor keamanan untuk 33 m/s (cc. 120 km/jam) dihitung.

Our most popular product among arborists
Detects the size and location of decayed or hollow regions
Works fast: a measurement can be completed in 5-10 minutes
Creates a 3D model of the trunk with multiple layers of measurement
Customizable wind load modeling is included in the software
Utilizes non-destructive technique using sound waves (no radiation)
For trees with thick bark, 12 cm long nails are also available
Usage Instructions
- Drive the transducers through the bark using a rubber hammer with even spacing around the trunk.
- Measure the distances between the transducers with a caliper and enter the measured data to the computer.
- Tap each transducer with a steel hammer to generate sound waves. ArborSonic 3D measures the travel times with microsecond precision to each transducer and transmits the data to the computer.
- The software calculates and displays the internal sound-velocity distribution of the tree.
- Measurements taken at various heights can be assembled into a 3D model.
