1.0 APPLICATIONS
1.1 PURPOSE:
DBI-SALA Digital Series Winches are to be used for
work positioning, personnel riding, material handling, climbing
protection, or rescue and evacuation. These winch models are
to be used with a DBI-SALA tripod, davit arm, or other support
structure, and may be used in situations where personnel or
materials need to be raised or lowered up to 300 feet (91.4 m).
1.2 WINCH APPLICATION TYPES:
A. WORK POSITIONING:
The Digital Winch is used to suspend
the worker in a work position, acting as the primary means of
support. Applications include suspending a worker in a work
seat or harness. A back-up personal fall arrest system (PFAS)
must be attached to the suspended employee.
NOTE:
OSHA requires that manual or powered winches be
independently evaluated and classi
fi
ed for use as a single point
suspension system. See OSHA regulation 29 CFR 1926.451, and 29
CFR 1910.28.
B. PERSONNEL RIDING:
The Digital Winch is used to raise or
lower a worker to a work level. At the work level the worker
is no longer supported by the winch. A back-up PFAS must be
attached to the employee while riding the winch.
C. RESCUE AND EVACUATION:
The Digital Winch is used to
raise or lower an endangered or injured worker, or rescue
personnel. Applications include permit and non-permit confined
space entry work. When possible, in emergency rescue or
evacuation situations, use a back-up PFAS.
D. CLIMBING PROTECTION:
The Digital Winch is used to
protect a worker ascending or descending a fixed ladder or
similar structure. It is recommended that this use of the winch
be restricted to structures where other means of climbing
protection; such as permanently installed ladder safety
systems or personal fall arrest systems are infeasible. For this
application, the following conditions must be met:
•
Ladder or steps are in good condition and allow for a
straight, continuous climb.
