Category: Arborist Rope

Arborist ropes are specifically engineered for the unique demands of tree work, prioritizing safety, performance, and durability in challenging environments. These ropes are essential tools for tree climbers and ground crews, used in a variety of applications including climbing, rigging, and tree support. Constructed from high-strength synthetic fibers like nylon and polyester, arborist ropes are designed to withstand the rigors of repeated use, exposure to the elements, and the dynamic loads encountered during tree care operations.

• Climbing Ropes: These ropes, typically conforming to CE EN 1891 standards, are low-stretch kernmantle ropes used for ascending and descending trees. They offer a balance of flexibility for knot tying and low elongation for efficient climbing. Common diameters range from 11mm to 13mm.
• Rigging Ropes: Used for controlled lowering of branches and logs, rigging ropes prioritize strength and abrasion resistance. Polyester is a common material choice due to its excellent UV resistance and low stretch characteristics. Diameters can range significantly based on the load requirements.
• Construction: Arborist ropes often feature a kernmantle construction, with a strong core (kern) providing the majority of the rope’s strength and a braided outer sheath (mantle) protecting the core from abrasion and wear. The number of strands in the sheath can vary (e.g., 16, 24, or 32-strand), influencing the rope’s handling characteristics and abrasion resistance.
• Materials: Core materials commonly include nylon (polyamide) for its strength and elasticity, while sheath materials often utilize polyester for its abrasion resistance, UV resistance, and low stretch. Some ropes employ a combination of both materials to optimize performance.

Key Specifications: When selecting an arborist rope, consider the following specifications:

• Diameter: Impacts handling and compatibility with climbing and rigging hardware.
• Minimum Breaking Strength (MBS): Represents the minimum force the rope can withstand before breaking.
• Elongation: Lower elongation is generally preferred for climbing ropes to minimize bounce, while some elongation can be beneficial in rigging ropes to absorb shock loads.
• Sheath Slippage: Measures the amount the sheath moves relative to the core under load; lower slippage is preferred for safety and performance.
• Weight per Meter: Affects the overall weight of the rope, which is a consideration for climbers.
• Certification: Look for ropes certified to relevant standards such as EN 1891, ANSI Z133, or other applicable safety standards.
