RESTRICTIONS
1. The Tether Track® Free Standing Cantilevered Monorail System shall be used as part of a complete active
fall arrest system. Neither Gorbel nor its distributor takes responsibility for the system as a whole. The Tether
Track® Free Standing Cantilevered Monorail System is designed and tested by Gorbel in accordance with
OSHA and ANSI Z359.1 & Z359.6 requirements using a minimum design factor of two. All components are
designed in accordance with AISC guidelines.
2. The end user shall be responsible to make sure that the complete Fall Arrest System shall be designed,
installed and used under the supervision of a qualified person in accordance with applicable OSHA regulations
and ANSI Z359 Fall Protection Code voluntary consensus standard. State and local jurisdictions may have
additional requirements.
3. It is the responsibility of the user to determine the sustainability of equipment and any attachments prior to each
use and to have certification inspection on a periodic basis with recurrence not to exceed once per year by a
qualified person.
4. Lanyards or self retracting lifelines (SRL) to be used with the Tether Track® Free Standing Cantilevered
Monorail System shall have a maximum arresting force (MAF) equal to or less than 900 lbs or they shall have
a maximum arresting force (MAF) equal to or less than the MAF rating of the Tether Track® Free Standing
Cantilevered Monorail System.
5. Customer chosen lanyards or SRL shall minimize freefall distance.
6. It is the responsibility of the end user to verify that the mounting height of this Tether Track® Free Standing
Cantilevered Monorail System will provide adequate fall clearance when used with the customer chosen lanyard
or SRL and harness.
7. Each trolley shall have no more than one person attached.
8. Trolleys are designed to freely move. To prevent a swing fall and the lengthening of the free fall distance, the
user shall verify the trolley maintains the closest possible distance to the user whenever he or she changes
position.
9. The Fall Clearance Zone shall be free of dangerous obstructions and electrical hazards.
10. The Tether Track® Free Standing Cantilevered Monorail System shall be installed per the general arrangement
drawing without deviation or modification.
11. This system is not designed to be used as a crane.
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.
LEADING EDGE
- The edge of the working surface that a person could fall off. This edge, if located parallel with the
Tether Track® Monorail, may restrict the lifeline from reaching a vertical orientation and cause off-vertical
(horizontal) loading of the anchorage system. Avoid sharp leading edges or use lifelines designed to withstand a
sharp leading edge 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...”
