PRODUCT DESCRIPTION:
Figure 1 illustrates 3M™ DBI-SALA™ Digital Series Winch. Digital Series Winches are used for work positioning, personnel riding,
material handling, climbing protection, or rescue and evacuation. These Winch models are to be used with a 3M Fall Protection
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 290 ft. (88 m). Figure 2 illustrates the components of the Digital Winch and Continuous Feed Winch.
A. Work Positioning: Applications include suspending a worker in a work seat or harness. A back-up fall arrest system must be
attached to the suspended employee.
B. Personnel Riding: At the work level, the worker is no longer supported by the Winch. A back-up fall arrest system must be
attached to the employee while riding the Winch.
C. Rescue and Evacuation: Used to raise or lower an endangered or injured worker or rescue personnel. Applications include
permit and non-permit confined space entry work. In rescue or evacuation situations, use back-up fall arrest system.
D. Climbing Protection: Used to protect a worker ascending or descending a fixed ladder or similar structure. The use of this
Winch should 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 straight, continuous climb.
•
The worker climbing the ladder is wearing a full body harness and the Winch line is connected to the dorsal (back) D-ring of
the harness.
•
The winch operator is trained and competent in the operation of the Winch.
•
No slack line is allowed to develop when the worker moves up or down the ladder.
•
Energy-absorbing lanyards be should be connected between the harness dorsal D-ring and the winch line.
