System Compatibility
Vi-Go Vertical Cable Lifeline Systems are designed for
use with Miller approved components. Substitution or
replacement with non-approved component combina-
tions, sub-systems, or both, may affect or interfere
with the safe function of each other and endanger the
compatibility within the system. This incompatibility
may affect the reliability and safety of the total system.
Vi-Go Systems must be used in conjunction with a
Vi-Go Cable Sleeve with auto-locking carabiner (or
other Miller approved connector) and a Miller full-body
harness equipped with a front attachment point desig-
nated for ladder climbing.
[NOTE: All instructions and warnings provided with
the cable sleeve, connector and harness must be read
and understood before using the equipment.]
System Capacity
A maximum of four users may simultaneously be
connected to a Vi-Go Vertical Cable Lifeline System so
long as the load-bearing capacity of the base structure
is adequate. For Vi-Go Systems using the 10 ft. (3m)
top bracket assembly, the number of users is limited to
two.
The distance between users must not be less than
5-1/4 ft. (1.6m) to ensure that, in the event of a fall,
the person falling will not strike a user below. (Note:
According to ANSI A14.3, only one worker may be on
the system between cable guides.)
Fall Clearance
Ensure that adequate clearance exists in the fall path
to avoid striking a lower level, some other object, or
another user.
2.2 System Warnings and Limitations

3.0 System Requirements
Before installation of a Vi-Go System, the structure or ladder on which the system is to be afxed must be certied
to be capable of withstanding the potential loads that may be applied in the event of a fall arrest and must meet
the specied ladder requirements.
Ladder Requirements
A ladder must be a xed ladder with rungs having outer diameters between 3/4 inch and 1-1/8 inches. According
to ANSI A14.3, the minimum width of the ladder should be 18 inches from inside rail to inside rail.
A system may be attached to square, diamond or L-shaped (angle iron) rungs so long as the rungs meet the mini-
mum 3/4 inch and maximum 1-1/8 inches outer diameter requirements. A spacer may be required for angle iron
installations. Please contact Miller Technical Services at 800-873-5242 for additional information and installation
assistance.
Top Bracket
Connection loads include system pretension and forces generated by arresting a fall. The load requirements vary
due to number of users on the system and installation to the structure (i.e., number of rung clamp assemblies
used).
For calculation purposes in determining the load each ladder rung must be able to withstand, assume the maxi-
mum load on each bracket is distributed evenly throughout the number of top bracket rung clamp assemblies.
[Example: Based on a single-user system with the top bracket installed with three rung connections, the assumed
load for each rung would be 1,100 lbs. (3,300/3).] An additional top bracket rung clamp assembly can be pur-
chased separately and used to spread the load requirements over four (4) rungs rather than three (3). [Example:
For a system with two (2) users the loads transmitted to each rung is reduced from 1,267 lbs. (3,800/3) to 950 lbs.
(3,800/4).]
Number of Simultaneous Users Maximum Load (lbs.)*
For Vi-Go AUTOMATIC and MANUAL Systems:
1 3,300 lbs.
2 3,800 lbs.
3 4,300 lbs.
4 4,800 lbs.
*The maximum load calculations provide a 2:1 safety factor.
Bottom Bracket
The bottom bracket connection must be capable of supporting a system load of 750 lbs. in the direction of loading.

This installation configuration ►
is only permitted with the 5 ft.
(1.5m) top bracket assembly
and limits the number of users
on the system to one (1).
The top bracket assembly may be installed to
extend above the ladder to allow workers to
step safety onto the platform without disconnect-
ing from the lifeline. It is recommended to be
mounted at the center of the ladder for ease of
use and access, but can be installed toward the
side of the ladder if required.
For typical installation of the 5 ft.
(1.5m) top bracket assembly, refer to
Figure 1a. This installation congura-
tion will accommodate up to four (4)
users simultaneously. The 7 ft. (2m)
and 10 ft. (3m) top bracket assemblies
are installed as shown in Figure 1b.
[Note: All systems using the 10 ft.
(3m) top bracket assembly are lim-
ited to two (2) users.]
An extra rung clamp assembly may
be used in the installation of the top
bracket to lower the loads transmitted
to each ladder rung (see Fig. 1c).
For systems limited to one (1) user,
the 5 ft. (1.5m) top bracket may be
installed with two rung clamp assem-
blies (see Fig. 1d). Ensure the
ladder will withstand the loads be-
tween the two rungs.
1. Place the top bracket against the
rungs of the ladder at the desired
height (see either Fig. 1a or 1b). In-
stall bottom rung clamp assembly rst.
For 5 ft. (1.5m) bracket: Place U-bolt around the
rung of the ladder and through the holes provided at
the bottom of the bracket.
For 7 ft. (2m) or 10 ft. (3m) bracket: Place bolts
through the holes provided at the bottom of the
bracket and through mounting plate on opposite side
of ladder rung as shown.
Install washers and torque fasteners to 20 plus or
minus 2 ft. lbs.
WARNING: The bottom U-clamp must be installed
correctly or the bracket may slip under load.
2. Continue to hold bracket against the rungs of the

2. Then connect quick link with cable to the shackle
on the underside of the inline shock absorber.
Tighten quick link until snug. Do not use if quick
link does not close and tighten.
NOTE: Ensure the cotter pin is through the
shackle bolt and bent over so that it will not back
out. DO NOT USE SYSTEM IF COTTER PIN IS
MISSING.
5.3 Installation of Intermediate Cable Guides
Intermediate Cable Guides are designed to keep the climber from
excessively deecting the cable and to protect the cable from chaf-
ing against the ladder or structure. Cable guides should be placed
at 25 ft. (7.6m) minimum to 40 ft. (12.2m) maximum intervals along
the cable from the top bracket to the bottom bracket. Cable guides
may be placed at any point along the cable that may come in con-
tact with the ladder or structure. For installations in situations of
vibration or high wind, consideration should be given to placing the
intermediates closer together.
