New England Tree-Line             

PRODUCT DESCRIPTION:

Tree-Line is a unique twelve strand construction, for each strand is composed of polyester wrapped around a polyolefin core. This provides for a firm, round, torque-free rope, that is lower stretch than a similar three strand rope. Tree-line is available in 5/8", 3/4", & 7/8" diameter.

FEATURES:

• Low stretch
• Torque-free, non-rotating, non-hockling
• Round construction
• Easy to coil and belay

APPLICATIONS:

• Bull Rope
• Arborist Climbing Rope

TECHNICAL SPECIFICATIONS:

Compliance to the above specifications is based upon testing according to the Cordage Institute Standard Testing Methods for Fiber Rope and/or ASTM D-4268 Standard Methods of Testing Fiber Ropes.
Weights - Are average and may vary +/- 5%
Tensile strengths - Are approximate average for new, unused ropes. To estimate the minimum tensile strength of a new rope, reduce the approximate average by 15% (Cordage Institute defines minimum tensile strength as two standard deviations below the average tensile strength of the rope).

SUNLIGHT/UV:

Very little degradation from UV. Can be used outside over long term if inspected regularly.

CHEMICALS:

Good resistance to most minerals / organics, acids, weak alkalis, bleaches and other oxidizing agents and most solvents.

HEAT:

Melting point of Polyester 480°F, progressive strength loss above 300°F.
Melting point of Polyolefin core 330°F, progressive strength loss above 200°F

DIELECTRICS:

Good resistance to the passage of electrical current. However in rope form, dirt, surface contaminants, water entrapment and the like can significantly affect dielectric properties. Extreme caution should be exercise any time a rope is in the proximity of live circuits.

SHEAVES:

Recommended D/d ratio is 8:1

WORKING LOADS:

No blanket working load recommendation can be made because it depends on the application and conditions of use, especially potential danger to personnel. It is recommended that the user establish working loads and safety factors based on professional and experienced assessments of risks. The working load is a guideline for the use of a rope in good condition for non-critical applications and should be reduced where life, limb, or valuable property is involved. Or exceptional service such as shock, sustained loading, severe vibration, etc. The Cordage Institute specifies that the Safe Working Load of a rope shall be determined by dividing the Minimum Tensile Strength by the Safety Factor. Safety factors range from 5 to 12 for non-critical uses, 15 for life lines.

SLK= Minimum Break Strength / Safety Factor

COATING:

Provided with an arborist performance coating for enhanced abrasion resistance.

COLOR:

White, Orange fleck

STANDARD LENGTH:

Available in standard 120, 150, 600, & 1200 ft lengths
