INTRODUCTION
Thank you for choosing a Tether Track® Free Standing Cantilevered Monorail by Gorbel to solve your fall
protection needs. Extensive testing, years of component history and quality manufacturing are leveraged to provide
the ultimate value and safety in your Tether Track® Rigid Rail Anchor System. The Free Standing Cantilevered
Monorail Systems are optimally designed to require a small support footprint while protecting a large fall zone. Up to
50 foot support centers are standard. These systems are also optimized for outdoor use by including ice and wind
loads, designing for wind buffeting per AASHTO guidelines, lining the enclosed track with a durable coating, utilizing
leveling nuts for the groutless column bases, and using corrosion resistant hardware.
The engineered systems comply with OSHA’s required safety factor of 2 and are designed in accordance with ANSI
Z359.6. Furthermore, Tether Track® Free Standing Cantilevered Monorail Systems are designed to be statically
proof tested up to 110% of the maximum arresting force (MAF) without incurring any visual permanent deformation.
Following a fall event, this allows the system to be readily returned to service after performing the inspection
procedures detailed in this manual.
When properly applied, configured and installed under the supervision of a qualified person, Tether Track® Free
Standing Cantilevered Monorail Systems will allow unsurpassed user mobility through the use of self-retracting
lanyards (SRLs) attached to Tether Trolleys™, freely rolling on clean, rigid, enclosed track. Superior safety is
achieved through minimizing fall distance, reducing swing falls, and eliminating secondary falls by keeping the
anchor point overhead on the Tether Track® Rigid Rail Anchor System. 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.
APPLICATION
Tether Track® Free Standing Cantilevered Monorail Systems are the best choice for providing coverage to a
rectangular fall zone where there is no existing support structure. 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:
Standard design is for a maximum arresting force of 900 lbs. and a maximum worker weight (with tools) of
310 lbs. If your SRL has a higher rating, it must be specified at the time of quote.
Foundation quantity may be minimized by using 1 or 2 person monorails with 50 foot support centers. For these
long spans, track plate style splices are used to keep the longest component to a 40 foot length for easier
shipping and handling. Systems with smaller support centers and shorter cantilevers may be able to be installed on
existing reinforced concrete floors. Alternatively, Free Standing Monorails (goal post style supports) may be used
to reduce foundation requirements. Foundation requirements provided on the General Arrangement Drawings are
based on 3000 psi concrete strength and 2500 psf allowable soil bearing strength.
This product meets all applicable OSHA and ANSI standards for fall 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 additional safety precautions, see pages 13 and 14.
