INSTALLATION
;
Installation of the 3M SALALIFT Winches must be supervised by a Qualified Person
certified by a Competent Person
the potential forces that could be encountered during a fall.
3.1
PLANNING: Plan fall protection systems prior to installation of the Winch. Account for all factors that may affect safety
before, during and after a fall. Consider all requirements, limitations and specifications defined in Section 2 and Table 1.
1.
Secondary Or Back-Up Fall Arrest System: When using the Salalift winch (8101000 series) as a support for work
positioning, a secondary or back-up fall arrest system is required. See OSHA 29 CFR 1910.28 and 1926.451. The
DBI-SALA tripod and davit arm has provisions for connection of a secondary or back-up PFAS. See sections 3.3 and
3.5 (A).
2.
Rescue: A means of dealing with an accident or emergency must be planned in advance. Response time can play an
important role in the survival of an injured worker. Users of this equipment must be trained in emergency procedures.
3.3
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.
B.
LOAD REQUIREMENTS: Figure 8 illustrates mounting the winch to the support structure and the load requirements.
The mounting bracket must support the loads shown in Figure 8.
•
Wire rope directional sheaves must have a minimum diameter of 2.5 inches (63.5 mm).
•
Mounting bracket connection to mounting surface must support a minimum load of 3,100 lb. (1,406 kg) in the
direction of pull, and 8,184 in*lb.. (925 N*m) moment load.
•
Attach mounting bracket to structure which will support specified loads.
•
Align cable drum and pulley as shown for proper winding on cable drum.
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 8. 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.
;
IMPORTANT: Position the winch and support structure in a location which allows the operator to safely use the
winch.
D.
QUICK-MOUNT INSTALLATION: See Figure 7. Mount the winch using the quick-mount bracket as follows:
1.
Pull out the locking detent pin (A) by depressing the button on end of the pin. Lift the winch into place and
position the slot in the bracket over the fixed pin on the support structure bracket.
2.
Push the top of winch in toward the support structure while the bottom rotates on the fixed pin. Align the holes
and push the detent pin (B) through until it stops. Ensure the pin locks in place.
3.
Slowly pull out the winch line. Route the line over the support structure pulley system. See the support structure
manufacturer's instructions for details.
E.
WELDED INSTALLATIONS: If welding the mounting bracket to a support structure it is recommended that the
welding be done by a certified welder. Portions of the mounting bracket that have been exposed due to welding
should be painted or otherwise protected from corrosion.

USE
4.1
BEFORE EACH USE: Verify that the work area and Personal Fall Arrest System (PFAS) meet all criteria defined in Section
2 and a formal Rescue Plan is in place. Inspect the Winch per the 'User' inspection points defined on the "Inspection and
Maintenance Log" (Table 2). If inspection reveals an unsafe or defective condition, do not use the system. Remove the
system from service and destroy, or contact 3M regarding replacement or repair.
4.2
OPERATION OF WINCH:
A.
CONNECTING WINCH LINE TO LOAD: See Figure 9. For applications that do not require a secondary PFAS, the
winch line (A) should be connected to the worker's harness back D-ring (E). For applications requiring a secondary
PFAS, the winch line should be connected to a Y-type lanyard (B) and this lanyard should be attached to the worker's
harness shoulder D-rings (D). The secondary lifeline (C) should be connected to the worker's harness back D-ring
(E). For material (G) handling applications, connect the winch line (A) to the load using a tie-off adapter (F) or other
anchoring device.
B.
SALALIFT WINCH (8101000 SERIES): Attach the winch to the support structure as described in section 3.3 (D).
Install the winch crank handle onto the high or low speed shaft by aligning the handle with the shaft and pushing
firmly inward until the handle snaps in place. To release the handle from the shaft, depress the handle release and
1 Qualified Person:
An individual with a recognized degree or professional certificate, and extensive experience in Fall Protection. This individual must be capable
of design, analysis, evaluation, and specification in Fall Protection.
2 Competent Person:
One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazard-
ous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.
