![]() ![]() ![]() Grasp the cable at a distance – (the length of the expansion insert, plus around 16 inches) and feed the insert towards the cable end.Select the correct length of expansion insert – this should be at least two thirds of the branch diameter.THE ASSEMBLY PROCESS – a step by step guide – The process of installation is easy for any arborist: The rope and anchor point should be sufficiently strong for the weight of the branch. The only acceleration will be from the rope extension so there will be little or no shock loading. The bracing should be installed as vertically as possible so that, should the branch fall, it will hang in the rope. Load/Support Cabling – If there is a threat of a broken branch falling to the ground with a potential of endangering life or causing damage to property, it can be secured by installing a static load/support cabling cobra system without a shock absorber. Static Braking Cabling – non-shock absorbing installations more intently restrict independent movement of involved branch parts to prevent a weak crotch from opening or re-opening. The Cobra model chosen is dependent on the base diameter of the branch to be cabled (see the table above). The non-shock absorbing method is Intended to minimize strain to limits and to prevent a weak crotch from opening or re-opening.ĭynamic Breaking/Cabling, Static Breaking/Cabling and Load/Support Cablingĭynamic Installations are the standard type used for cobra – they restrict excessive swinging motion and disrupt wind loads between branches to help support the crotch below. This method is assembled in the two third region of the crown to make optimal use of the leverage effect. Cobra bracing is fully recyclable and offers four different systems, depending on the branch size of the tree:Ĭobra Bracing can make the use of a shock absorber which is designed to prevent a ‘crotch’ (the meeting point of two branches) from splitting. Finally, the anti-abrasion hose allows the rope to slide freely around the connection point.Įasy installation – Quick and easy to install, the material is incredibly strong yet comfortable to handle, with its soft mesh braiding and does not require the use of specific tools scissors are required to cut the rope and hose and a lighter or heat torch are required to shrink the end cap.Īdditional features The Cobra bracing system features ‘end caps’ – coloured identification of the installation year. Another key feature is the ‘expansion insert’, which flattens the contactĪrea, reducing pressure that may contribute to girdling. One of the system’s unique features is it’s use of shock absorbency through an integrated shock absorber component. It is not aesthetically displeasing.ĭurability and longevity – Cobra Bracing retains 12 years of rated tensile strength thanks to UV materials. Safety – Cobra Bracing meets the technical requirements of the German ZTV standards and the American ANSI A300.Īppearance – This system is almost invisible from the ground even when the trees are not in leaf. It is installed to offer a great elasticity it grows with and protects the tree. Cobra bracing has been a successful technological advancement and is the ‘go-to’ solution for arborists worldwide with its proven track record since 1993.īenefits to trees – Cobra Bracing is not harmful to trees and can be comfortably adapted to a variety of tree structures. Cobra Bracing provides added structural support by effectively limiting the movement of branches, thus reducing the risk of damage, and extending the tree’s lifespan. Nowadays, ‘Cobra Bracing’ is the most effective type of tree support system. However, since then, technology and innovation has improved enormously. This involved the invasive use of steel cables and rods, which was subsequently harmful to trees. The original method used to stabilise and protect trees was known as ‘steel bracing’ – a system used 20 plus years ago. Some of the factors that can weaken a tree are: Splitting of the trunk or at branch junctions. Common indications that trees might be in a less-than-optimal condition are: ![]() Any arborist understands that damaged or ageing trees can cause a risk of harm to life and property, due to broken or fallen branches. ![]()
