Environmental Hazards
Use of this equipment in areas where environmental
hazards exist may require additional precautions to limit the
possibility of injury to the user or damage to the equipment.
Hazards may include, but are not limited to, extreme
temperatures, caustic chemicals, corrosive environments,
high voltage power lines, explosive or toxic gases, moving
machinery, and sharp edges. Do not expose the equipment
to any hazard which it is not designed to withstand. Consult
the manufacturer in cases of doubt.
• Guide rail must be kept clean--free of dirt, residual mortar,
and other substances.
• Use of this system is not suitable when the user is
positioned on an unstable surface, fine-grain material,
or particulate.or entities authorized, in writing, by the
manufacturer.
3.0 System Requirements
Before installation of a GlideLoc Kit, the structure and
ladder on which the system is to be affixed must be certified
to be capable of withstanding the potential loads that may
be applied in the event of a fall arrest and must meet the
specified ladder requirements.
Ladder Requirements
For the kits, a ladder must be a fixed ladder with rungs
having outer diameters between 3/4 inch (19.1mm) and
1-1/4 inches (31.8mm). For ladder rungs with larger
diameters, rung clamps with longer hardware are available
which will accommodate rungs up to 1-3/4 inches (44.5mm).
According to ANSI A14.3, the minimum width of the ladder
must be 16 inches (406.4mm) from inside rail to inside rail.
For non-standard ladder rungs, please contact Miller
Technical Services at 800-873-5242 for additional
information and installation assistance.
The integrated shock absorber of the Body Control I,
Comfort, Comfort
2
and Universal II fall arresters limits fall
arrest forces to 1350 lbf. (6kN). This is the maximum force
on a ladder system for a single user.
To calculate the maximum working load rating on a ladder
system with more than one user, the following formula can
be used as a guide:
Ladder Working Load Rating = (Fall Arrest Force + (Maximum
# of Users – 1 x Weight of Worker))
Example: Ladder rated for 4 users at 250 lbf. each:
Ladder Working Load Rating = (1350 lbf. + (3 x 250 lbf.))
= 2100 lbf. Ladder Working Load
To calculate the maximum working load rating on an indi-
vidual ladder rung for more than one user, the following
formula can be used as a guide:
Ladder Rung Working Load Rating =
(Fall Arrest Force + (Maximum # of Users – 1 x Weight of Worker))
# of Ladder Clamps
Example: Ladder rated for 4 users at 250 lbf. each on a
GS0040 system:
Ladder Rung Working Load Rating = (1350 lbf. + (3 x 250 lbf.))
7
= 300 lbf. per Ladder Rung
Important notes:
1. Working load rating DOES NOT INCLUDE A SAFETY
FACTOR.
2. Specific ladder compliance standards may vary
and must be used when required to determine
rung force requirements and safety factors.
3. The fall arrester limits the maximum fall arrest
force to under 1350 lbf. (6kN). This is the maximum
force on a ladder system for a single user.
4.0 description of System Components
4.1 GlideLoc System Kit
1) 12kN End Stops
• For use at top and bottom of rail system.
•
Prevents incorrect insertion of the fall arrester and
unintended disengagement of the fall arrester from the rail.
2) Guide Rail w/Rail Connector
• Installs easily to vertical fixed ladders with varying
rung diameters and spacing.
• Markings identify the upper end of the rail to prevent
incorrect installation.
• Rail connector connects two guide rails sections.
• Rail available in 10 ft.-1 in. (3.08m) increments in
galvanized steel, stainless steel and aluminum.
3) Body Control I, Comfort or Comfort2
Fall Arrester
•
Fall arrester purchased separately.
• Durable stainless steel & aluminum construction (Body
Control I/Comfort) or complete stainless steel construction
for maximum corrosion-resistance (Comfort
2
).
• Quick and easy to install with single-hand operation.
• The safety pin protruding from the side of the fall
arrester, together with the end stop, prevents the fall
arrester from being inserted incorrectly in the rail.
• Allows smooth, hands-free climbing with or without
leaning back.
• Locks quickly in the event of a fall.
• Integrated shock absorber/fall indicator limits fall
arrest forces to 1350 lbf. (6kN) and provides for ease
of inspection.
OR
Universal II Fall Arrester
•
Fall arrester purchased separately.
• Complete stainless steel construction for maximum
corrosion-resistance.
• May be inserted or removed at any point along the
guide rail.
• Quick and easy to install with single-hand operation.
• Failsafe design ensures correct usage.
• Allows smooth, hands-free climbing.
• Locks quickly in the event of a fall.
• Integrated shock absorber/fall indicator limits fall
arrest forces to
1350 lbf. (6kN) and provides for
ease of inspection.
4) Rung Clamp
• Secures guide rail to ladder rungs.
• Available in galvanized steel, stainless steel & aluminum.
