Overview
This document provides detailed specifications and applications for various types of ropes used in arborist rigging, event rigging, and other demanding applications. It includes information on materials, dimensions, weights, and breaking loads, as well as guidelines for care and use.
Specifications
  • Draco Lines: Designed for arborist rigging with diameters ranging from 12mm to 16mm and lengths of 50m to 200m, offering high strength and durability.
  • D12 Max (SK78): Used for event rigging, available in diameters from 2.5mm to 17mm, suitable for high-load applications.
  • D12 Plus: Similar to D12 Max but available in larger diameters (18mm to 44mm) with exceptional strength and low stretch.
  • V12 and T12: High-strength, low-stretch ropes made from Vectran® and Technora® respectively, with excellent heat resistance.
  • Static LSK: Low stretch kernmantle rope for rope access and abseiling, meeting EN1891 standards.
Materials and Construction
  • Ropes are constructed using materials such as polyester, HMPE, Vectran®, and Technora®, each offering benefits like UV resistance and high strength.
  • Coatings like ArmourCoat enhance abrasion resistance and durability.
Chemical Resistance
The document includes a table showing the residual strengths of synthetic fibers after exposure to various chemicals, indicating the durability of materials like nylon, polyester, and HMPE under different conditions.
Care and Use
  • Rope strengths are tested according to international standards, and users are advised to determine appropriate safety factors and working loads.
  • Splicing is recommended for terminations to minimize strength loss, while knots can significantly reduce rope strength.
  • Regular inspection is crucial to ensure ropes remain fit for service, with attention to external and internal abrasion.
Inspection and Maintenance of Ropes
  • Internal Yarn Condition: Check for abrasion, which may indicate exposure to abrasive particles or inter-yarn abrasion.
  • Glazing: Indicates excessive heat exposure, causing yarns to melt.
  • Discoloration: May indicate dirt causing internal abrasion or chemical damage.
  • Inconsistencies: Lumps or thin sections suggest internal damage due to overloading or shock loads.
  • Rope Longevity: Ropes should be retired after an appropriate period, especially if failure poses risks.
Storage Recommendations
  • Store ropes in a clean, dry place, away from sunlight and extreme temperatures.
  • Avoid storing on dirty floors or dragging over rough ground to prevent abrasion.
  • Keep away from chemicals and rinse with fresh water for long-term storage.
  • Handle braided ropes correctly to avoid excessive twist.
Use with Sheaves, Pulleys, and Rollers
  • Using ropes around sheaves reduces strength and life. A sheave diameter 8-10 times the rope diameter is generally sufficient.
  • The groove profile should support the entire rope, ideally a semicircle 10% greater than the rope diameter.
  • Ensure sheaves rotate freely to maintain rope life.
