Installation, documentation, inspection
and maintenance
There is no absolute break prevention solution or 100 % guarantee that
crown parts of trees will not fall down even using tree cabling/crown
cutting measures.
Note
INSTALLATION
Tree cabling systems must be installed by profes-
sional installers as a thorough understanding of
tree stability and dynamic wind loads is required for
installation.
DOCUMENTATION
The installation of a crown tree cabling must be
documented by specifying the location, installation
date and reason as well as the type of system used
and its tensile strength and durability.
INSPECTION
To guarantee the long-term efficiency of tree cabling
systems, regular visual checks as well as regulatory
control in the form of a visual inspection by qualified
individuals are essential.
The inspection interval depends on the condition of
the tree and the safety standards that can reasona-
bly be expected for the affected traffic and is usually
2 years.
MAINTENANCE
Defects discovered during inspection must be
corrected promptly. This is usually done together
with other tree maintenance work, e.g. cutting and
trimming. Serious defects, insufficient splice length
or chafing problems must be fixed immediately.
YEARLY COLOUR-CODED END CAPS
There is a different colour for every year. This colour together with
the actual year printed on the end caps is used to indicate the
installation year.
