System Compatibility; Making Connections - Honeywell Miller 8172 Manuel D'utilisation

2.0 System Compatibility

Miller rope grabs and vertical lifelines are designed for use with Miller approved components.
Substitution or replacement with non-approved component combinations or subsystems 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.
6,000 lbs. (27kN).

3.0 Making Connections

Connecting to the Anchorage
The vertical lifeline must be attached to an anchor point capable of supporting 5,000 lbs. (22.2kN)
per worker or meet OSHA 1926.502 requirements for a safety factor of two.
Anchorage requirements based on ANSI are as follows:
strengths must be multiplied by the number of personal fall arrest systems attached to the anchorage.
Make sure connections are compatible in regards to size, strength, and shape. Never use an
anchor point which will not allow snap hook or carabiner keeper to close and lock, or which is
capable of causing a load to be applied to the keeper. Rope grabs are connected to the vertical
lifeline as per section 4.0, Installation.
Connecting to the Body Wear
Rope grabs should be connected to either the back D-ring on the full-body harness (see Fig. 1)
using an approved lanyard, or to the front chest D-ring on the full-body harness (see Fig. 2) using a
connector, such as a locking carabiner.
(According to ANSI standards, a front
D-ring attachment element may be used
for fall arrest only in applications where
the personal fall arrest system limits the
maximum free fall distance to
2 ft. (0.6m) and limits the maximum
arrest force to 900 lbs. (4.0kN).)
is 3 ft. (.9m) for use with trailing rope
grabs (8172, 8173, and 8175 models).
(1.8m) for use with manual rope grabs
(8174 model).
