INTRODUCTION
Thank you for choosing a Tether Track® Swing Arm by Gorbel to solve your fall protection needs. Tether Track®
Swing Arms have been optimally designed to provide maximum protection for workers exposed to a fall hazard.
When properly applied, configured and installed under the supervision of a qualified person, Tether Track® Swing
Arms will allow the ultimate in user mobility by providing a mobile rigid anchorage for the attachment of a lanyard or
self-retracting lanyard (SRL). Using a SRL combined with the engineered cantilever anchorage, provides the
superior safety of a rigid system by minimizing fall distance while maximizing energy absorption of the fall arrest
force. This reliable performance combined with an ANSI approved Managed Fall Protection Program gives the user
the utmost safety assurance and encourages further safe work practices.
Tether Track® Swing Arms are designed using the most current ANSI guidelines and comply with all OSHA
requirements for a fall arrest anchorage system. The use of ANSI’s Maximum Average Arresting Force (MAAF) has
been incorporated into the design standards for the Tether Track® Swing Arm. Tether Track® Swing Arm systems
are designed to be statically proof tested up to 125% of the MAAF. If using lanyards or SRLs that are just rated for
Maximum Arresting Force (MAF), this MAF rating shall not exceed the MAAF rating of the Tether Track® Swing
Arm. When loaded through proof testing or during a fall event, the Tether Track® Swing Arm will not incur any
visual permanent deformation and may be placed back into service after performing the inspection requirements
detailed in this manual. Tether Track® Swing Arms have additionally been designed and tested to not sustain any
visible deformation under the maximum OSHA allowed 1800 lb. dynamic arresting force. All engineered Tether
Track® Swing Arm systems comply with OSHA’s required safety factor of 2 and are designed in accordance with
ANSI Z359.6.
The W-shape jib design provides the best economic flexibility to fit your specific fall zone requirements and
provides the best design to allow for the greatest fall clearance height. This combined with a mobile trolley within
our enclosed track all mounted on a freely pivoting hinge allows for the maximum ease of movement. These proven
designs have been utilized in Gorbel’s crane products for many years. Refer to the Introduction to Jib Cranes and
Introduction to Work Station Cranes for more details and additional definition of terms.
APPLICATION
Tether Track® Swing Arms are the best choice for providing coverage to a semi-circular fall zone. The rigid
anchorage, maintaining the anchorage trolley overhead and the use of a “Class A” Self Retracting Lanyard provides
the best solution to minimize fall distance when fall clearance height is restrictive. Note: specify Class A requirement
at time of quote, standard design is for “Class B” SRLs. The pivoting arm can be swung out of the way of overhead
cranes or equipment when the system is not in use. Thrust and pull forces are provided to determine the adequacy
of the available support structure. These forces are calculated using proof loading requirements of 1.25 * MAAF and
dead weight. When an existing support structure is unavailable or inadequate, Free Standing Tether Track® Swing
Arms can be provided. Foundation requirements are provided based on 3000 psi concrete strength and 2500 psi
allowable soil bearing strength.
When using a Tether Track® Swing Arm for more than one worker, either the motorized or friction brake option is
required. Both of these options, when properly adjusted, prevent excessive movement of the Swing Arm during a fall
event while limiting high lateral impact stresses in the swing arm and supporting structure.
This product meets all applicable OSHA and ANSI standard for all protection.
Dimensions contained in this installation manual are for reference only and may differ for your particular
application. Please refer to the enclosed General Arrangement Drawing for actual dimensions.
Normal safety precautions: These include, but are not limited to:
• Checking for obstructions in the fall clearance zone
• Coordinating fall hazard activities with assigned rescue personnel
• Making sure that end stops are in place
• Making sure that trolley freely moves
• For Motorized Swing Arms, verifying that lock out is in place
• When used by more than one worker at the same time, verifying friction brake or motorized clutch restricts
Swing Arm rotation
For additional safety precautions, see page 21.

WARNINGS
1. Do not throw away these instructions.
2. Only competent erection personnel familiar with standard fabrication practices should be employed to assemble
these anchor systems. Gorbel is not responsible for the quality of workmanship employed in the installation of an
anchor system according to these instructions. Contact Gorbel Inc. at 600 Fishers Run, P.O. Box 593, Fishers,
New York 14453-0593, 800-821-0086, for additional information if necessary.
3. Consult a qualified structural engineer to determine if your support structure is adequate to support the loads
generated by thrust and pull (wall/column mounted) or anchor bolt force, overturning moment, or axial load (free
standing) of your anchor system. Gorbel Inc. assumes no responsibility for the adequacy or integrity of mounting
surface.
4. Read and understand this manual before using equipment.
5. This manual should be read and understood in its entirety, and used as part of a training program as required by
OSHA or any state and local regulatory agency.
6. This and any other included instructions shall be provided to the users of this equipment. The user shall
understand the proper equipment use and limitations.
7. The Tether Track® Swing Arm Anchor System is only to be used as part of a complete fall protection system.
The buyer or user is responsible for the safety and compatibility of the complete system.
8. Any component replacement, addition or change to the anchor system or the complete system requires
evaluation by a qualified person.
9. Any fall event can result in injuries. The proper use of this equipment can substantially reduce an injury. For
maximum safety, the worker shall be trained in the proper use of this equipment and all of the components of
the fall arrest system.
10. Before each use, the equipment shall be inspected as outlined in the inspection section of this manual.
11. The rated capacity, the rated maximum average arresting force, and the rated maximum arresting force of the
Tether Track® Swing Arm Anchor System shall not be exceeded. If the lanyard or SRL connected to the Tether
Track® Swing Arm does not list a maximum average arresting force, the maximum average arresting force
rating listed shall not exceed the rated maximum average arresting force of the Tether Track® Swing Arm
Anchor System.
12. A managed fall protection program which includes a rescue plan is required for the safe use of this equipment.
A worker suspended from this system can lose vital blood flow to the brain as blood pools in the legs. This is
referred to as suspension trauma.
13. Reference the American Institute of Steel Construction (AISC) Manual of Steel Construction, Specification for
Structural Joints using ASTM A325 or A490 Bolts (section 8.d.2) for the proper procedures to follow when using
any torque tightening method.
14. Do not field modify the Tether Track® Swing Arm Anchor System in any way. Any modifications without the

DEFINITION OF TERMS
AUTHORIZED PERSON - ANSI defines an authorized person as a “person assigned by the employer to perform
duties at a location where the person will be exposed to a fall hazard”.
COMPLETE FALL ARREST SYSTEM - A complete fall arrest system consists of three main components:
A) Engineered Anchor System - Gorbel’s Tether Track® has been engineered to provide the maximum safety
possible. This system allows for the greatest worker mobility through Gorbel’s ergonomic enclosed track
design. It provides minimal fall distance by keeping the anchor point overhead and rigid.
B) Body Support - Only a full body harness is allowed for fall arrest systems. Proper fitting and wearing of the
harness is critical so that it can evenly dissipate the fall arrest forces to the strongest body parts.
C) Connecting Means - This is the link between the anchor and body support. A self-retracting lifeline is
recommended. This provides maximum mobility and minimum fall distance. An energy absorbing lanyard
may also be used. These components have a maximum arresting force rating. Gorbel’s standard Tether
Track® design is based on a maximum arresting force of 900 lbs. or less.
FALL CLEARANCE ZONE - The space below the person where there is a potential to fall. This space must remain
clear of obstructions to prevent injury from contact with any objects during a fall event.
QUALIFIED PERSON - ANSI defines a qualified person as “A person with a recognized degree or professional
certificate and with extensive knowledge, training and experience in the fall protection and rescue field who is
capable of designing, analyzing, evaluating and specifying fall protection and rescue systems...”

STEP 2 - WALL/COLUMN MOUNTED SWING ARM INSTALLATION
2.1 Determine position of upper-formed channel bracket on support structure. Drill
bolt holes (see chart 1A and diagram 1A, page 4, for bolt diameter and bolt to
support structure.
2.2 Determine position of lower formed channel bracket by measuring distance
between bracket centers; clamp bracket to support structure. Align brackets by
dropping plumb bob (by others) through pivot holes and making sure string is
centered in pivot holes (diagram 2A). Shim, if necessary, between mounting
surface and formed channel brackets (shims by others).
2.3 Drill bolt holes for lower bracket (see chart 1A and diagram 1A, page 4,
for bolt diameter) and bolt to support structure. Do not torque bolts until
Swing Arm has been checked for drift (Step 2.5).
2.4 Attach Swing Arm assembly to formed channel using hardware provided (diagram 2B). Be sure that thrust
washers are in position. Tighten nuts on pivot bolt until lockwashers are compressed, being sure boom
freely rotates.
2.5 Carefully swing arm through entire travel to ensure boom is clear of obstructions and does not drift.
If Swing Arm drifts, support structure may be inadequate and/or shims may be required between mounting
surface and channel brackets (refer to Step 2.2 for pivot mounting assembly alignment).
2.6 Torque mounting bolts (grade 5 or better, by others) to manufacturer’s specifications.
2.7 Proceed to Step 5 on page 10.
TIP: Upper and lower formed channel (brackets) are identical unless a rotation stop is welded to the bracket. In
this case, the rotation stop bracket is the upper bracket (refer to Step 10, page 16).
STOP!
Do not proceed if your support structure does not meet the loading requirements determined in Step 1.4.

STEP 3 - FREE STANDING MAST INSTALLATION
3.1 INSTALLING ANCHOR BOLTS
3.1.1 Refer to diagram 3A or 3B and chart 3A for bolt hole size and pattern for base plate thickness.
3.1.2 Cast-in Anchor Bolts with Poured Foundations
(6 or 12 bolt pattern):
A) Anchor bolts (by others) must:
• be 1” diameter for 1-1/4” diameter base plate holes and
1-1/4” diameter for 1-1/2” diameter base plate holes.
• be embedded 3/4 of footer depth (L).
• have minimum of two threads above nut after installation.
B) Create steel-reinforced concrete foundation using
recommendations shown in diagram 3C.
Refer to chart 1B, page 5, or chart 1C, page 6, for footer depth (L)
and footer width (M) in diagram 3C.
Note: 7/16” thick, wafer board, bolt hole templates are available to
facilitate anchor bolt alignment. Foundation requirements are based
on soil pressure of 2500# per square foot. Concrete
pressure recommended for foundation is 3000# per square
inch of compressive force.
Note: Foundation/concrete must cure seven (7) days prior to mast
installation. Foundation/concrete must cure 28 days prior to
using Swing Arm.
C) Proceed to Step 3.2, page 9, for mast installation and
plumbing.
STOP!
Do not proceed if your foundation does not meet the size and loading requirements identified in Step 1.4.

STEP 3 - FREE STANDING MAST INSTALLATION (CONTINUED)
3.1 INSTALLING ANCHOR BOLTS (CONTINUED)
3.1.3 Post-Installed Anchor Bolts with Shallow Foundations (6 bolt pattern):
In addition to the requirements identified in Step 1.4, a minimum 6” thick reinforced concrete floor that is
free of cracks, seams, expansion joints, and walls is required. Foundation requirements are based on a
concrete compressive strength of 3000# per square inch, a soil bearing pressure of 2500# per square foot,
and a modulus of subgrade reaction of 150# per square inch per inch.
A) Anchor bolts (by others) must:
• have an ICC-ES listing demonstrating suitability for the application.
• be installed in accordance with the manufacturer’s instructions and requirements.
B) Base plate may be used as a template to drill holes in concrete floor. Follow anchor bolt manufacturer’s
recommendations for drill bit size, depth, and special inspection requirements.
Note: Base plates are designed for poured foundations. Hole size may exceed anchor bolt manufacturer’s
recommendations. Contact Gorbel® Customer Service if a custom base plate is required. Drill
bushings or equivalent may also be used to reduce hole clearance. Bushings must not protrude above
base plate. If base plate hole diameter is greater than
bolt diameter plus 1/4”, refer to AISC Design Guide 1 for
minimum washer size and thickness recommendations.
C) Install anchor bolts and hardware according to
manufacturer’s installation instructions. Diagram 3D shows
a typical installation.
Note: Before tightening hardware, follow instructions in Step
3.2 for applying and curing grout.
3.2 Installing and Plumbing Mast
A) Cover entire base plate area with one inch of non-shrink precision grout.
B) Set mast into place and make sure that the base plate is completely
seated in the grout.
C) Thread a plumb line through Swing Arm mounting bracket holes and
hole in tapered plug (by others) as shown in diagram 3E.
D) Adjust mast as required until plumb line is centered in all the mounting
hole brackets.
E) Once mast is plumb and grout has cured, fully
tighten anchor bolt hardware.
F) Verify mast is still plumb.
DO NOT USE A LEVEL

STEP 8 - DRIVE INSTALLATION (WALL MOUNTED) (OPTIONAL)
Holes must be drilled in wall column to mount
reducer assembly (refer to General Arrangement
Drawing for hole pattern, bolt size, and pattern
location). Spacer plates (when required) are
shipped loose.
8.1 The clutch is pre-tightened by Gorbel.
If any additional clutch adjustment is
required, refer to the friction clutch
instructions below. If the clutch is not
tightened properly, the lever arm may
slip and the Swing Arm may not rotate
properly.
8.2 Layout reducer mounting location on
support structure. Ensure that mounting
surface of support structure is plumb
along the plane comprising upper and
lower pivot mounts and drive mount.
Locate and drill holes.
8.3 Install swing arm according to instructions in Step 2 on page 7 or Step 4 on page 10.
Hardware by others (grade 5 or better).
8.4 Lower drive assembly into place with lever arm engaged on pivot block and install
mounting hardware (grade 5 or better, by others) but do not tighten. Verify that the
drive is aligned with the axis of rotation of the swing arm and that there is
approximately a 1” gap between the bottom of the lever arm and the top plate of the
Swing Arm (diagram 8B). Torque drive mounting bolts (refer to chart 8A for proper
torque rating).
Friction Clutch Installation
During normal operation, adjustment to compensate for friction lining wear may
be necessary. The frequency of these adjustments will be dependent on the
frequency of overloads occurring.
8.5 CLUTCH TORQUE ADJUSTMENT - SYSTEMS USED INDOORS
Loosen the locking screw on the adjusting nut. Using the hook wrench
provided, turn the adjusting nut counterclockwise until the drive
sprocket can turn freely in the clutch. The clutch can now be
retightened to the proper torque setting. Turn the adjusting nut
clockwise until it is hand tight. Using the hook wrench provided,
tighten the adjusting nut an additional two full revolutions. After the
adjustment is made, tighten the locking screw to ensure that the
adjusting nut doesn’t loosen. The proper torque setting is achieved when
the drive sprocket will not slip under normal operating conditions
(diagram 8C).

TIP: The friction clutch is shipped pretightened by Gorbel. If the clutch begins to slip during initial use,
allow the clutch to slip several times then retighten the clutch per the instructions below. The purpose
for allowing the clutch to slip several times is to establish a uniform surface on the friction linings.

STEP 9 - ELECTRIFICATION INSTALLATION (OPTIONAL)
9.1 When ordered with a motorized Fall
Arrest system, an electrical control
enclosure with pendant, junction
box, wire and conduit will be
included (shipped loose). Hardware
to mount these components is
supplied by others.
9.2 Enclosure must be mounted on a
rigid structure away from all
moving components and within
reach of user to allow access to
pendant and electrical disconnect.
Typically it will be mounted on same
wall/structure that the Swing Arm is
located on.
9.3 Level enclosure and mount to structure (hardware by others).
For hole pattern, reference diagram 9A. Mount junction box
(hardware by others) below vertical member of Swing Arm,
diagram 9A.
9.4 If not already connected, wire limit switches into top of junction
box (diagram 9B).
9.5 Connect power cable from motor to terminal in junction box.
Ensure that conduit is located such that it will not be crushed by
rotating Swing Arm.
9.6 Connect conduit and wire from junction box to main enclosure
and make motor and limit switch connections.
9.7 Customer is responsible for providing incoming power to match
required voltage of motor.
9.8 Reference drawing E and E-1 for pendant and enclosure schematics
when required.
9.9 Attach limit switch tab to bottom of vertical member of Swing Arm
(diagram 9C) so that is does not interfere with the limit switch mount
plate. Adjust limit switch lever arms to make contact with limit switch
tab (diagram 9D). Position limit switches such that the Swing
Arm is prevented from making contact with any object and the
fall zone is away from dangerous machinery or conditions.
Ensure that limit switch mounting hardware is tightened.
Note: Limit switch should be adjusted with power supply due
to deceleration once the switch has been activated.

STEP 10 - ROTATION STOP INSTALLATION (OPTIONAL)
10.1 When ordered with a rotation stop,
one bracket will have a plate welded
to it with slots to accept rotation stop
bolts. This bracket must be installed
as the upper bracket. Additionally, an
angle with mounting hardware is
included to be installed on the vertical
member of the Swing Arm. Refer to
diagram 10A for the following steps.
10.2 Follow Swing Arm installation
instructions in Step 2 on page 7 or
Step 4 on page 10. When tightening
the top pivot bolt, use the included
insert as a socket to hold the nut while
tightening the bolt (a deep socket or
other method may be used at the
installer’s discretion). Once the bolt is
tight, the insert may be removed but
should be kept in the event the bolt ever needs to be removed.
10.3 Install the rotation stop studs and nuts in the stop plate but do not fully tighten yet. Install the stop angle with
included hardware and adjust vertically so the bottom of the angle is even with the top of the flange on the
stop nut (diagram 10A). Torque hardware per chart 8A, page 14.
10.4 Locate rotation stop hardware in the stop plate such that when the nut hits the stop angle, the Swing Arm is
prevented from hitting any obstruction and that the fall zone is away from any dangerous machinery or
conditions. Orient the nuts so the flat of the hex contacts the flat of the stop angle. Torque stop hardware
per chart 8A, page 14.
STEP 11 - FINAL STEPS
11.1 Check to make sure all bolts are tight and lockwashers are compressed.
11.2 Grease all fittings (use Lubriplate #630-AA or equivalent).
11.3 If necessary, touch up system with paint provided.
11.4 Install yellow rubber tracdoms on open ends of steel track.
11.5 Verify capacity labels are legible from the ground or egress location.
11.6 For more than a one worker system, verify that the required brake or drive is installed and verify that only a
SRL with sufficient extra payout is being used. Additional line is required to allow the Swing Arm to move
during a fall event without the SRL reaching its maximum length which may cause the second worker to lose
his or her balance.
11.7 Proof testing may be performed if required by state or local jurisdictions. The qualified person responsible
for this fall arrest system may also request a proof load test. The Swing Arm Anchorage System has been
designed to withstand a static proof load test not to exceed 125% of the rated MAAF with no visible
permanent deformation. The trolley shall be slowly loaded to avoid additional dynamic loads. The proof load
should be applied for a minimum of one minute. After this test is complete, the Swing Arm Anchorage
System shall be inspected as if a fall event had occurred.
11.8 Keep Packing List, Installation Manual, General Arrangement Drawing, and any other inserts filed together
in a safe place.

FALL ARREST SYSTEM REQUIREMENTS
Vertical Fall Clearance: The Tether Track® trolley will follow a worker along the length of the Swing Arm and remain overhead
as long as the worker remains directly under the Swing Arm. However, as the worker moves
horizontally away from the Swing Arm, the arm will likely remain until the worker gently moves it or a fall event occurs and the
arm moves to the leading edge. If a SRL is being used, the extra payout of the lifeline must be accounted for in the fall clearance
calculation. The worker must never exceed a 30 degree vertical offset angle with the trolley. The extra fall clearance distanced
required is provided in the following calculation:
ODH = (TS - WS - DR) * (1/cosӨ- 1) (diagram 1)
Where: ODH = the offset distance height required to be included in the fall
clearance calculation
TS = the trolley saddle height
WS = the working surface height
DR = the lowest height of worker’s harness dorsal D-ring from
working surface
Ө= the vertical offset angle the worker is allowed (30 degrees
maximum)
Here’s a typical example:
• Worker Height (WH) = 6 ft.
• Minimum SRL Length including connectors (SL) = 2 ft.
• ANSI Z359.14 Class B SRL, Maximum Activation and Deceleration
Distance (Arrest Distance, AD) = 4.5 ft.
• Safety Factor used in this example (SF) = 1.5 ft.
• Working Surface Height above nearest obstruction, ground or floor in this
case (WS) = 10 ft.
• Worker may be required to kneel or crouch.
• Worker is allowed to work with a vertical offset angle of 20 degrees of his
or her SRL line.
What is the lowest Trolley Saddle the Swing Arm may have? SRL’s typically
require that there be no slack in the line (see manufacturer’s specific usage requirements). To achieve this, the trolley
saddle must be the minimum SRL length above the workers dorsal ring.
Minimum TS = WS + WH - 1 ft + SL = 10 + 6 - 1 + 2 = 17 ft.
• Here 1 ft is taken as the distance from the dorsal ring to the worker’s full height.
The trolley saddle may also be calculated to limit the worker’s horizontal travel away from being directly under the Swing
Arm. Additional information is SRL has a maximum length (SML) = 8 ft.
TS = WS + DR + SML * cosӨ= 10 + 3 + 8 * cos (20 degrees) = 20.5 ft.
• Here 3 ft is used as the minimum height of the dorsal ring above the working surface for a worker that
is crouching or kneeling (DR = 3).
Is there sufficient clearance below the working surface to arrest a fall?
ODH = (TS - WS - DR) * (1/cosӨ- 1) = (20.5 - 10 - 3) * (1/cos (20 degrees) - 1) = .5 ft.
Required Clearance below working surface (RC)
RC = ODH + AD + SF + 1 + .33 + 2
• Here 1 ft is allowed for harness stretch, .33 ft or 4” is maximum allowed deflection for a rigid system,
and 2 ft is allowed for additional leg clearance for a crouching person.
RC = .5 + 4.5 + 1.5 + 1 + .33 + 2 = 9.83 ft
• 9.83 feet is less than 10 ft, therefore there is sufficient clearance for this application.
This example shows the importance of including the additional clearance requirements for allowing work horizontally away from
the Tether Track® trolley. If the maximum allowed offset from vertical angle of 30 degrees was used, the required clearance
would have exceeded the available clearance.
It is recommended to work directly below the anchorage trolley. However for some applications this may be difficult to achieve.
The above calculation is identical to a swing fall calculation. However, in this case the Swing Arm will move to keep the lifeline
vertical instead of the worker swinging. Note: even with the drive or friction brake option, the Swing Arm may move to the vertical
lifeline position during a fall event.

FALL ARREST SYSTEM REQUIREMENTS (CONT.)
Horizontal Fall Clearance: The Swing Arm, without the drive or friction brake, is designed to freely pivot so that a
small gently applied force will allow the Swing Arm to be slowly moved into a directly overhead position.
The freely pivoting Swing Arm will reduce impact forces on the worker through the inertial acceleration of the Swing
Arm for an offset from vertical fall. The Swing Arm may slowly rotate until an obstruction is encountered or the swing
reaches its rotation limit (Swing Arm’s full rotation is 210 degrees). If any dangerous obstructions are within the fall
clearance zone, optional rotation stops are required to limit the fall clearance zone and keep it free of dangerous
obstructions.
Multiple User Systems: If a single Swing Arm is to be used by more than one worker, the Swing Arm must have an
optional friction brake or drive. In addition to this, only SRLs with extra available line shall be used. In the event of a
fall, the Swing Arm must be restricted from movement so as to prevent a second worker from being pulled off
his/her
work surface. If the Swing Arm is equipped with the optional drive, it must be moved into the desired position and the
drive electrical enclosure properly locked out prior to anyone working at height and using this system. If the Swing
Arm is equipped with the optional friction brake, it must be moved into the desired position and the brake properly
engaged prior to anyone working at height and using the system.
The brake and drive rely on friction to hold the Swing Arm in position. In the event of a fall, the Swing Arm may
move to vertically align the activated lifeline and may rotate up to an additional 10 degrees. To reduce the potential
of a second worker from falling, extra payout line is required in the SRL.
The worst case would occur when the falling worker is located near the pivot point and is at the maximum allowable
vertical offset distance, and the second worker is located at the end of the boom and is at the maximum allowable
vertical offset distance in the opposite direction. The following calculation is provided to determine the additional line
required.
Horizontal Offset Distance (HOD) = (TS - WS -
WH + 1) * sinӨ
• Rotation of Swing Arm to align with
leading edge at 4 ft from pivot (RSA) =
arc tan (HOD/4)
• Possible Horizontal Movement at end
of Swing Arm (HM) = SPAN * tan (RSA
+ 10 degrees)
• Required SRL Length (RSL) = ((TS -
WS - WH + 1) ^2 + (HM + HOD) ^2)
^.5
Here’s an example using the values in the
previous example and the Swing Arm span is
20 ft.
HOD = (20.5 - 10 - 6 + 1) * sin 20 =
1.9 ft.
RSA = arc tan (1.9/4) = 25.4 degrees
HM = 20 * tan (25.4 + 10) = 14.2 ft.
RSL = ((20.5 - 10 - 6 + 1) ^2 + (14.2 +
1.9) ^.5 = 17 ft.
For this example, the maximum length of the SRL
should be at least 17 feet. Further restrictions (other
than a maximum offset angle of 20 degrees) may be
enforced. For example, if the workers must remain 6 feet from each other, the maximum length of the SRL should
be at least 10.5 ft. It is recommended to remain directly under the Swing Arm.

WARNING
Sudden movements or hard pulls on the lanyard or lifeline must be avoided. For Swing Arms without a friction brake
or drive, a large force applied horizontally perpendicular to the Swing Arm will create inertia forces that may be
difficult to resist and may cause a fall event.
