(16kN) when certification exists (see ANSI Z359.1 for certification
definition), or (B) 5,000 lbs. (22kN) in the absence of certification.
When more than one PFAS is attached to an anchorage, the
anchorage strengths set forth in (A) and (B) must be multiplied by the
number of PFAS attached to the anchorage. Per OSHA 1926.500 and
1910.66: Anchorages used for attachment of a PFAS shall be
independent of any anchorage being used to support or suspend
platforms, and must support at least 5,000 lbs. (22kN) per user
attached, or be designed, installed, and used as part of a complete
PFAS which maintains a safety factor of at least two, and is
supervised by a qualified person.
WARNING: Read and follow manufacturer's instructions for the personal fall
arrest equipment selected for use with the winch and support structure.
IMPORTANT: Body belts are not allowed for free fall situations. Body belts
increase the risk of injury during fall arrest in comparison to a full body
harness. Limited suspension time and the potential for improperly wearing a
body belt may result in added danger to the user’s health.
3.4 INSTALLATION OF WINCH TO SUPPORT STRUCTURE:
A. MOUNTING BRACKET: These winches incorporate a “quick-mount”
style bracket for attachment to the support structure. DBI/SALA
tripods, davit arms, and other support structures supplied by
DBI/SALA, include a bracket that mates with the winch quick-mount
bracket. All DBI/SALA winches include the quick-mount bracket.
When using the 8102001 series winch with the 8004176 Wall Mount
Bracket, a mounting adapter kit is required. Contact DBI/SALA for
more information.
B. LOAD REQUIREMENTS: Figure 5 illustrates mounting the winch to
the support structure and the load requirements. The mounting
bracket must support the loads shown in Figure 5.
C. GEOMETRIC REQUIREMENTS: Refer to the support structure
manufacturer's instructions for geometric requirements. Installations
of the winch to support structures other than those provided by
DBI/SALA must meet the geometric requirements shown in
Figure 5. Position the support structure so the load and the lifeline of
the winch can be directed over the work area when installed. For
personnel use, do not position the support structure where the
worker will have to swing under the support structure to reach the
work area. Avoid positioning the support structure where the working
line may abrade against sharp edges.
