Core Flip Line Instructions
Usage:
Unreeling:
Remove rope properly from reels to prevent kinking. The rope should be
removed by pulling it off the top while the reel is free to rotate. To
proceed in any other manner may cause kinks or strand distortion.
Handling: Never stand in line with rope under tension. If a rope
fails it can recoil with lethal force. Synthetic rope has higher recoil
tendencies than natural fiber rope. Reverse rope ends regularly. This
permits even wearing and assures a longer, useful life. When using tackle
or slings, apply a steady, even pull to get full strength from rope.
Caution: Overloading and Use of Working Loads:
Because of the wide range of rope use, exposure to the several factors
affecting rope behavior, and the degree of risk to life and property involved,
it is impossible to make blanket recommendations as to working loads.
However, to provide guidelines, working loads are tabulated for rope in
good condition with appropriate splices, in non-critical applications
and under normal service conditions.
A higher working load may be selected only with expert knowledge of conditions
and professional estimate of risk and if the rope has not been subject
to dynamic loading or other excessive use, has been inspected and found
to be in good condition and is to be used in the recommended manner and
the applications does not involve elevated temperatures, extended periods
under load or obvious dynamic loading (see explanation below) such as
sudden drops, snubs, or pickups. For all such applications and for applications
involving more serious exposure conditions, or for recommendations on
special applications, consult the manufacturer. Many uses of rope involve
serious risk of injury to personnel or damage to valuable property. This
danger is often obvious, as when a heavy load is supported above one or
more workers. An equally dangerous situation occurs if personnel are in
line with a rope under tension. Should the rope fail, it may recoil with
lethal force. Persons should be warned against the serious danger or standing
in line with any rope under tension.
In all cases where such risks are present, or there is any question
about the loads involved or the conditions of use, the working load should
be substantially reduced and the rope properly inspected.
Dynamic Loading Voids Normal Working Load:
Normal working loads are not applicable when rope is subject to significant
dynamic loading. Instantaneous changes in load, up or down, in excess
of 10% of the lines rated working load constitutes hazardous shock
load and would void normal working loads. Whenever a load is picked up,
stopped, or swung there is an increased force due to dynamic loading.
The more rapidly or suddenly such actions occur, the greater the increase
will be. In extreme cases, the force put on the rope may be two, three
or even more times the normal load involved. Examples could be picking
up a tow on a slack line or using a rope to stop a falling object. Therefore,
in all such applications such as towing lines, lifelines, safety lines,
climbing ropes, etc., working loads as given DO NOT APPLY.
Users should be aware that dynamic effects are greater on a low elongation
rope such as polyester than on a high elongation rope such as nylon, and
greater on a shorter rope than on a longer one. The working load ratings
listed contain provision for very modest dynamic loads. This means, however,
that when the working load has been used to select a rope, the load must
be handled slowly and smoothly to minimize effect and avoid exceeding
provision for them.
Example: A load of 3500 lbs. is being lowered using 5/8 diameter
Double Esterlon, which has a maximum recommended working load of 4000
lbs., with 15 feet of line payed out the line is accidentally slipped
- dropping the load one foot before arresting the fall.
Question: How much energy did the rope have to absorb, what was
the maximum load on the rope, and has the rope been overloaded or damaged?
work done (Ft. Lbs.) - (weight)(length of fall) = 3500 Ft. Lbs.
rated maximum working energy absorption
capacity = (weight of the rope in use)(working energy absorption capacity
for the type of line being used)
From the data page Double Esterlon has a working energy absorption capacity
of 544 ft. lbs. per pound of rope and a weight of 13.7 lbs. per 100 ft.
or .137 lbs./ft.
rated maximum working energy absorption capacity of 16 ft. of 5/8 Double
Esterlon =(16 ft.)(544 ft. lbs./lb.) = 1192 ft. lbs.
In this example, 2.19 lbs. of rope (16 ft. x .137 lbs./ft.) in use must
absorb 3500 ft. lobs., or 3500 ÷ 2.19 lbs. equals 1596 ft. lbs./lb.
of rope. The right column indicates ft. lbs. of energy absorbed
in capacity per pound of rope. Corresponding to 1596 ft. lbs./lb., you
will find that the rope was loaded to approximately 48% of rated BS. From
the data table, 48% of the 5/8" diameter Double Esterlons strength
(16,000 lbs.) is 7680 lbs.
In this example the maximum working energy absorption capacity has been
exceeded by nearly 3 times. The actual load on the rope reached 7680 lbs.
or 3680 lbs. in excess of the maximum working load of 4000 lbs. Although
difficult to quantify, some degree of the ropes integrity has been
compromised and prudent safety practice would call for downgrading or
discarding the line. If in our example the load had fallen 7 feet instead
of 1 foot, the rope would have broken.
Abrasion: Avoid all abrasive conditions. All rope will be severely
damaged if subjected to rough surfaces or sharp edges. Chocks, bits, winches,
drums and other surfaces must be kept in good condition and free of burrs
and rust. Pulley must be free to rotate and should be of proper size to
avoid excessive wear. Clamps and similar devices will damage and weaken
the rope and should be used with extreme caution. Do not drag rope over
rough ground. Dirt and grit picked up by rope can work into the strands,
cutting the inside fibers.
Chemicals: Avoid chemical exposure. Rope is subject to damage by
chemicals. Consult the manufacturer for specific chemical exposure, such
as solvents, acids, and alkalies. This is particularly true for natural
fiber rope. Consult the manufacturer for recommendations when a rope will
be used where chemical exposure (either fumes or actual contact) can occur.
Temperature: Effect on tensile strength. The tensile strength charts
apply to ropes tested at normal room temperature (70°F). Ropes have
lower tensile strengths at higher temperatures 30% (or more) lower at
the boiling point of water (212°F) and continuing on down to zero
strengths for nylon and polyester at 480°F and 300°F for polypropylene.
Also continued exposure at elevated temperatures can melt and part synthetic
ropes or cause permanent damage.
Splicing: Join rope by splicing. Knots can decrease rope strength
by as much as 60%. Use the manufacturers
recommended splices for maximum efficiency. Other terminations can be
used but their strength loss with a particular type of rope and construction
should be determined and not assumed.
Top
Storage And Care:
All
rope should be stored clean, dry, out of direct sunlight, and away from
extreme heat. Some synthetic rope (Particularly polypropylene, polyethylene,
and aramid) may be severely weakened by prolonged exposure to ultraviolet
(UV) rays unless specifically stabilized and/or pigmented to increase
its UV resistance. UV degradation is indicated by discoloration and the
presence of splinters and slivers on the surface of the rope.

Inspection:
Avoid using rope that shows signs
of aging and wear. If in doubt, destroy the used rope. If there is any question,
destroy the used rope. No type of visual inspection can be gurarnteed to
accurately and precisely determine actual residual strength. When the fibers
show wear in any given area the rope should be respliced, eliminating the
damaged area, downgraded or replaced.
Check the line regularly for frayed strands and broken yarns. Pulled strands
should be rethreaded into the rope if possible. A pulled strand can snag
during a rope operation.
Both outer and inner rope fibers contribute the strength of the rope. When
either is worn, the rope is compacted or hard which indicates reduced strength.
The dielectric strength of rope in this condition is also reduced.

Use
& Instructions:
Instructions:
The
information contained herein is not exhaustive and specifications are
subject to change in accordance with the CE regulations. Individuals using
these products should be trained or under the direct supervision of a
trained expert in the use of these ropes.
USE:
Yales static Arborist climbing lines are designed for use as
general-purpose Arborist climbing lines and tree surgery rope. They are
not for use in a personal fall arrest system and should always be used
in conjunction with ascending, descending and safety hardware and devices
for positioning work.
STORAGE and CARE:
To ensure safety and performance, the inspection and maintenance of
climbing and lifting lines should be among every arborists primary concern.
- Inspect
all ropes for breaks, cuts, abrasion and melted or fused fiber prior
to each use.
- Wash
ropes periodically to remove dirt and grit. Simply rinse lines with
a garden hose, and allow them to air dry. DO NOT use solvents, bleach,
or harsh detergents when washing lines, and never apply a heat source
when drying. Improper handling and care can dramatically alter the properties
of a rope.
- Coil
rope loosely, for storage, being sure to remove any excess twists or
kinks. To maximize rope life, always store each line in a dark dry place.
ROPE
WEAR and OBSOLESCENCE:
Upon examination of the rope, if damage is found, remove the rope
from service, retire it immediately, cut it into small pieces and discard
it, then replace it with an undamaged line.
Excessive
wear may be indicated by broken or cut strands that reduce the ropes
strength throughout the length and not just the area of damage. As a general
rule, retire the rope when more than 3 broken or cut strands are visible,
or if two adjacent strands are compromised.
Excessive
wear can also be indicated by melted or fused fibers, which is generally
the result of an abused rope. The melted or fused polyester fibers result
from surface temperatures over 480 degrees F, caused by excessive load
weights, rapid descents or a hot exhaust heat source. The damaged fibers
will compromise the rope strength and it should be retired immediately.
Normal
wear is indicated by the appearance of small fuzzy fiber breaks on
the rope, that creates a fuzzy texture known as "mild abrasion".
This is considered good wear and will not effect the performance of the
rope. The nubby surface actually protects the underlying fiber from further
wear.
Chemical
attack or contamination of the rope may produce localized discolorations
caused by anything from gear and chain oil to gasoline and battery acid.
If any doubt exists whether or not the rope has been contaminated it should
be retired.
Abrasion
of the rope should always be avoided. All ropes will be severely damaged
if subjected to rough surfaces or sharp edges. Chocks, bits, winches,
drums and other surfaces should be kept clean and free of rust and burrs.
Ensure proper functioning, size and condition of pulleys used. Clamps
and locks will damage and weaken rope and should be used with extreme
caution.
TEMPERATURE:
The tensile strengths of the ropes tested were done at room temperature
(70 F). Higher temperatures lower the tensile strengths of the rope. At
the boiling point of water (212 F) a decrease in strength of 30% or higher
can result.
TERMINATION:
Splicing of the Arborist lines should be done by qualified individuals
only.
PERFORMANCE:
The Arborist ropes mentioned in this information package have been CE
marked in accordance with the clauses indicated in EC directive 89/686/EEC
Annex II and the paragraphs of EN1891: (1998) as detailed in Technical
File 001, Rev 3. These ropes are intended for static climbing and lowering
applications only. Working loads and ultimate strengths apply only to
new or like new ropes in good condition used under normal service, which
have not been subjected to excessive wear or used in critical applications.
Overloading of the rope is never recommended and can dramatically reduce
a ropes capabilities and life.
Dynamic
loading or shock loading the rope constitutes excessive wear and voids
normal working loads, the rope should be retired. Instantaneous changes
in load, up or down, in excess of 10% of the lines rated working load
constitutes a hazardous shock load. Whenever a load is picked up, stopped
or swung there is an increase in the force on the rope due to dynamic
loading. The more sudden the change in load is, the greater the force
put on the line is.
MARKING:
The CE accreditation is awarded after meeting the applicable technical
standards described in the performance section. And having exhibited robust
production processing and the Quality Assurance procedures necessary to
ensure a reproducible process that includes traceabilty and in house testing.

SHIPPING:
No special packaging is necessary for transportation. Hanks should
be bagged or boxed to prevent snags and maintain cleanliness and reels
should receive standard wraps, covers or boxed as necessary.
WARNING:
If in doubt of the ropes condition or previous usage retire the rope immediately.
Not all damage to a rope is visible. A single shock load or a load over
its rated working load can greatly reduce a ropes performance and result
in damage, serious injury or death. Tree surgery is inherently dangerous
and the improper use or selection of your equipment can be fatal. Only
trained experts or users under the direction of an expert should be using
these products. These ropes do conduct electricity especially when damp
or wet. Avoid contact with all overhead cables and consult the local electrical
authority for information.

Core Flip Line Instructions
INSTRUCTIONS:
The information contained herein is not exhaustive and specifications
are subject to change in accordance with the CE regulations. Individuals
using these products should be trained or under the direct supervision
of a trained expert in the use of these lines.
USE:
Yales Wire Core Flip lines are designed for use as work positioning
lanyards. They are not for use as a personal fall arrest system and should
always be used in conjunction with an approved Arborist climbing saddle.
Never use for another purpose.
STORAGE
and CARE:
To ensure safety and performance, the inspection and maintenance of
your wire core flip lines should be among every arborists primary concern.
- Inspect
all lines for breaks, cuts, abrasion, melted or fused fiber and wire
fray, wire kinks or breaks prior to each use. Inspect all hardware for
function and damage prior to use
- Cleaning
of the wire core sleeve periodically to remove dirt and grit will ensure
a good grip on the line. Do not soak the lines in water. Simply moisten
a clean cloth and wipe down the sleeving and allow them to air dry.
DO NOT use solvents, bleach, or harsh detergents when washing lines,
and never apply a heat source when drying. Improper handling and care
can dramatically alter the properties of a line.
- Coil
the line loosely for storage, being sure to remove any excess twists
or kinks. To maximize the flip lines life, always store each line in
a dark dry place.
LINE
WEAR and OBSOLESCENCE:
Upon examination of the line, if damage is found, remove the line
from service, retire it immediately, discard it, then replace it with
an undamaged line.
Excessive
wear may be indicated by broken or cut fiber strands that reduce the
sleeves strength throughout the length and not just the area of damage.
As a general rule, retire the line when more than 3 broken or cut strands
are visible on the sleeve, or if two adjacent strands are compromised.
Any
sign of wire abrasion, broken strands or kinks in the wire are cause for
retirement.
Excessive
wear can also be indicated by melted or fused fibers, which is generally
the result of an abused rope. The melted or fused polyester fibers result
from surface temperatures over 480 degrees F., caused by excessive load
weights, rapid descents or a hot exhaust heat source.
The
damaged fibers will compromise the strength of the sleeve and it should
be retired immediately.
Normal
wear is indicated by the appearance of small fuzzy fiber breaks on
the sleeve, which creates a fuzzy texture. Known as "mild abrasion"
this is considered good wear and will not effect the performance of the
flip line. The nubby surface actually protects the underlying fiber from
further wear.
Chemical
attack or contamination of the line may produce localized discolorations
caused by anything from gear and chain oil to gasoline and battery acid.
If any doubt exists whether or not the line has been contaminated it should
be retired. A chemical attack can corrode and weaken the wire core of
the flip line and may not be visible under the sleeve.
Abrasion
of the line should always be avoided. All lines will be severely damaged
if subjected to rough surfaces or sharp edges. Adjusters and Prussic loops
need to be clean and free of burrs to prevent damage. Clamps and locks
will damage and weaken rope and should be used with extreme caution.
Small
bend radii and sharp edges can cause crimps and or kinks in the line and
should always be avoided.
All
hardware should be inspected prior to use for proper functioning, burrs,
deformation and cracks. Improper snap lock function could cause serious
injury or death! Retire any questionable line.
TEMPERATURE:
The tensile strengths of the sleeves tested were done at room temperature
(70 F). Higher temperatures lower the tensile strengths of the sleeve.
The wire core is not effected by variations in the normal temperature
range of use.
TERMINATION:
Splicing of the Wire Core Flip lines should be done by qualified individuals
only.
PERFORMANCE:
The arborist lines mentioned in this information package have been
CE marked in accordance with the clauses indicated in EC directive 89/686/EEC
Annex II and the paragraphs of EN358: (1999) as detailed in Technical
File 002, Rev 1. These lines are intended for work positioning applications
only.
Working
loads and ultimate strengths apply only to new or like new lines in good
condition used under normal service, which have not been subjected to
excessive wear or used in critical applications. Overloading of the line
is never recommended and can dramatically reduce its capabilities and
life.
Dynamic
loading or shock loading the line constitutes excessive wear and voids normal
working loads, the line should be retired. Instantaneous changes in load
in excess of 10% of the lines rated working load constitute a hazardous
shock load. Whenever a load is stopped there is an increase in the force
on the line due to dynamic loading. The more sudden the change in load is,
the greater the force put on the line is.
