A installed cabling system is safe as long as controls and maintenance are executed correctly. Precise control intervals are often defined by municipalities or regional tree care standards! To optimize maintenance the non-invasive crown-stabilisation system tree save© has been developed. This multi-component system consists of a tree-bracing strap with a built-in overload display, a ordinary tree-bracing strap and a hollow-braided rope.

If the crown-stabilisation system is put under considerable pressure through movements in the crown or the breaking off of the secured section of the crown (load> 75 % of the system breaking load), this is displayed on a coloured indicator on the fixing strap. The functionality of the cabling system remains unaffected. The visibility of the overload indicator (15 to 20 meter) enables a rapid monitoring of the crown-stabilisation system from the ground.
