shock-absorber cobra 8t
Hardness: 60° shore
Dimensions: d = 45 mm, l = 500 mm
Low-load oscillation width: ca. 200 mm
Range of action: as from a load of 10 daN
The cobra 8t shock-absorber improves the dynamic properties of cobra 8t hollow cable. With its help, branches swinging in opposite directions in the wind are softly slowed down and the catching shock at the end of the braking process is reduced by 20 % - the so called "Karate effect" does not occur anymore. That way, the cobra 8t shock-absorber provides effective protection from branch breakage.
Beyond this, it allows the cobra-cabled tree to oscillate in gentle summer breezes, which supports the diameter growth and thus the future resistance to breakage of the tree. That low-load oscillation width is about 20 cm and is provided irrespective of the cabling length - a clear advantage over dynamic systems that work with cable expansion only. The length release of the shock-absorber begins under a load of 10 daN - 10 kg already.
This makes a cobra cabling a hardly perceptible but highly effective breaking protection for the tree.
