Tipping Stability
Estimates of lower inclination at stem base
Verified prognosis of required tipping load
To estimate tipping stability, the quality of the root-soil anchorage is analyzed. Damage in the root or soil area becomes apparent from the progression of the measured inclination of the soil-root matrix under a defined load, using high-precisioninclinometersand dynamometers (load cells).
Tipping curve with little inclinations
The load-inclination values are quite similar with trees at different locations at the beginning of the tipping process. The inclination in the pulling test is compared to the typical curve and is the basis of the estimation.
Estimating the tipping load
Arbostat suggests the failure load from a defined limit value on the basis of known correlations. As the inclination behavior disperses considerably more beyond this point, a conservative approach is applied.
Graphic display of safety reserves
Based on the expected wind load and the forecasted overturning load, a safety assessment is generated in graphical form. The progression of the inclination values immediately reveals whether the behavior during the pulling test aligns with the assumptions used for the extrapolation.
