Gefa Tree Slings

Gefa Tree Slings are high-quality tree slings developed for safe and gentle handling of trees during guying and support. These pressure-distributing slings are made of hollow braided polyester or polyamide without a core for easy splicing, with integrated friction protection that protects the tree from damage. They meet ZTV-Baumpflege standards and are GS-tested for high safety and reliability. Available in breaking strengths of 2 t, 4 t, and 8 t with widths of 60-80 mm, perfect for dynamic tree guying depending on stem diameter.

Features

• Integrated friction protection for optimal tree protection and minimal bark damage.
• Pressure-distributing design that spreads the load over a wide area.
• GS-tested for high safety and quality.
• Low elongation (polyester) or higher elongation (polyamide) depending on the model.
• Easy installation and splicing directly in the tree without tools.
• High system breaking strength with a guarantee of at least 8 years according to ZTV-Baumpflege.
• Tree-friendly, wide edition for long-term use in arboriculture.
• Sophisticated product based on many years of field testing in tree protection.

Technical Specifications

• Breaking strength: 2 tons, 4 tons, or 8 tons (system breaking strength, initially higher for long lifespan).
• Width: 60 mm (2 t and 4 t), 80 mm (8 t).
• Lengths: Customizable within model range (see table below).
• Material: Hollow braided polyester (low elongation) or polyamide (higher elongation).
• Compatible with stem diameters up to 80 cm for the 8 t model according to ZTV recommendations.
• Max elongation: Low under normal load, up to 12-25% under extreme load.

Size Chart

Please note: Choose a model based on stem diameter – 2 t up to 40 cm, 4 t up to 60 cm, 8 t up to 80 cm. For static guying, double the breaking strength. Contact us for advice on splicing or compatible system components such as shock absorbers.
