ArboStApp™

Tree safety evaluation software

Mobile tree stability evaluation – even without diagnostic devices

Software for determination and comparative evaluation of:

  • Tree wind load and the safety effect of reduction pruning
  • Stability reduction by deteriorations in trunk/branch cross-sections
  • Tipping-stability reduction by root decay and/or trenching
  • Available in different languages (German, English, French, Russian)
  • Combines ArWiLo™ and ArboMech™ with comparative safety-balancing based on cross-section condition and wind-load (reduction).

ArboStApp provides arborists and experts with a tool allowing the determination of strength loss due to structural defects in the cross sections of stems and branches and anchorage plate losses in relation to canopy size and expected wind-loads. In addition, the application enables evaluation of load reduction by crown reduction pruning to further achieve higher safety in damaged trees. The inputs are based on the users visual observations rather than diagnostic instruments but enable accurate (if not as precise) estimations of safety which are sufficient for many tree assessment purposes. However, the precision of the evaluation can be increased by putting in results from proper sonic tomography or resistance drilling with density-calibrated devices.

Typical working Steps

Take/Load picture

Mark crown border

Set stem base point x

Put in tree height

Note tree ID / data

Calculate wind load

Adapt (wind/site) parameters

Draw cross section (intact and deteriorated parts)

Draw root plate (intact and deteriorated parts)

Define safety levels

If required draw crown reduction pruning cuts until sufficient safety is achieved

Save data record.

The Word Resistograph

The U.S. Trademark Trial and Appeal Board (TTAB), in late October 2019, dismissed the petition of IML Instrument Mechanic Labor, Inc. for cancellation of the RESISTOGRAPH® trademark in the USA “with prejudice”. This means that the RESISTOGRAPH® trademark continues to be an exclusive trademark belonging to Frank Rinn, the inventor of the term (“RESISTOGRAPH”) for his inventive high resolution resistance drilling devices. Frank Rinn has been developing these high quality machines in Germany since 1986 and his RESISTOGRAPH® trademark is registered in approximately 40 countries. Only machines made by Rinntech are the original Resistograph® devices and entitled to use the Resistograph® trademark. Only data collected with a machine made by Rinntech provide Resistograph® data.
