At present, the most accepted method for evaluating the safety and stability of trees is the pulling test. It involves applying a bending load on the trunk via a cable attached to the tree. The method can be used either to assess the uprooting stability of the tree, or to establish the risk of trunk breakage.

Remark: there are overlaps among the equipments needed for DynaRoot and Pulling test. If you order both of them at the same time you can ask for a switchable Dual Elastometer Unit and High Precision Inclination and Deformation Recorders.


Make sure you follow all the safety instructions throughout the test!

  1. Attach the cable to the trunk in the crown of the tree, as high as possible.
  2. Choose an anchor point in the appropriate direction, about 10 to 15 m from the tree.
  3. Set up the winch and ropes according to the guide.
  4. Install the load cell.
  5. Install the inclinometer sensors.
  6. Install the extensiometer sensors.
  7. Connect all sensors to the central unit.
  8. Switch on the units, and press “Tara” on the load cell.
  9. Start the Pulling Test software.
  10. Start measurement by loading the cable slowly and evenly using the winch.
