The Cobra Shock Absorber 2 T / 4 T is an EPDM shock absorber that optimises the dynamic behaviour of Cobra cabling systems. It reduces shock loads on branches, cuts the so‑called “karate effect” by around 20%, and increases the break resistance of cabled trees. Designed for professional tree care and tree safety, with controlled activation starting at low loads.
Enhanced dynamics for Cobra cabling systems
The shock absorber improves the dynamic response of Cobra cables by progressively slowing down branch movements. Catching shocks at maximum deflection are reduced by approximately 20%, limiting sudden peak loads on anchor points and branch unions.
Protection and physiological tree movement
In addition to protection against branch failure, the device allows controlled, small-amplitude movement under light wind (low-load oscillation width approx. 20 cm). This promotes diameter growth and wood growth, supporting the natural development and future break resistance of the tree.
