  • Page 6: Intended Application

    PiCUS TreeQinetic Handbuch 3.2 Intended application The PiCUS TreeQinetic System is intended for use as measurement technology in tree static pull tests. In a pull test, the tree under examination is subjected to a controlled load using a measured force, while the reaction of the trunk and roots to this load is recorded. The tree's response to the known load is compared to the expected wind load during a storm, and this ratio expresses its stability or break safety.

    PiCUS TreeQinetic Handbuch 4.1.5 Overload-Indicator 4.1.5.1 Safety first! The static tree pulling test is an established method for assessing the stability and break safety of trees. However, conducting such a test requires a high level of expertise, experience, and care. When applying large forces to the tree, extreme caution must be exercised because sudden and unexpected structural failure of the tree could result in it falling, in whole or in part, onto nearby individuals or infrastructure (vehicles, buildings, etc.).
