3.0 INSTALLATION
3.1 PLANNING: Plan your Fall Protection system prior to installation of the Davit Fall Arrest System (FAS). Account for
all factors that may affect your safety before, during and after a fall. Consider all requirements defined in Table 1 to
determine the correct fasteners and placement for mounting the System on the anchorage structure.
3.2 INSTALLATION:
Step 1: To set up the hoist base, lay out all parts on the ground. See Figure 9.
Step 2: Remove leg pins (D) and rotate leg tubes (E) in leg sleeves (F) from transport/storage position (G) to operating
position (H). See Figure 9.
;
Leg assemblies must be in operating position (H) at all times when using the hoist.
Step 3: Insert leg sleeves (F) into base center section (I). The width of the base may be adjusted by selecting different
holes (J) in the leg sleeve to install pin (K). See Figure 9.
;
Base must be pinned into position through the hole in both the center section and the leg sleeve (K) at all times
when using the hoist. See Figure 10.
Step 4: Tighten the tri-screws (L) after the desired width is obtained to remove play from the base. See Figure 10.
Step 5: Move the base into position over the opening. Adjust the base height and level using adjuster screw (M) and level
indicator (N). See Figure 10.
;
Base must be level at all times when using the hoist
Step 6: To set up the hoist mast assembly, insert the lower mast (O) into base sleeve (P). See Figure 9.
Step 7: Ensure the stop bolt (Q) faces the front of the sleeve (P), and that the lower mast (O) rotates freely throughout its
range of rotation. See Figure 11.
Step 8: Lock the lower mast (O) into position by tightening the tri-screw (L). Do not over tighten, as this may interfere with
mast rotation in a rescue situation. See Figure 11.
Step 9: Install the upper mast assembly (R). Ensure the locating key (S) on the lower mast (O) completely engages the key
way slot (T) of the upper mast (R). See Figure 11.
Step 10: To avoid tipping the base when swinging the mast side to side, adjust the base according to the following:
•
Determine the maximum operating offset of the Variable Offset Mast. See Figure 12. Pin Positions (PP) 1-4 regulate
the Top Pulley (A4) and Bottom Pulley (A3) offsets. The table in Figure 12 shows the maximum offset (MAX) and
minimum offset (MIN) for each pulley in all 4 pin positions. Maximum offset is determined when the adjustable gusset
(V) is fully collapsed (no visible threads). Minimum offset is determined when the adjustable gusset is fully extended.
Note: In Figure 12, the Variable Offset Mast is in Pin Position 4 with the gusset fully collapsed.
•
Adjust the base according to the positions diagram shown for the base (W) and match the Base Pin Position (BPP)
setting with the setting of the Variable Offset Mast Pin Position (PP) (e.g. Mast Pin Position 4 must use Base Pin
Position 4). See table in Figure 13.
•
Level the base by adjusting the screw legs (M) to center the bubble in the level indicator (N). See Figure 10.
4.0 USE
4.1 BEFORE EACH USE: Verify that your work area and Fall Protection system meet all criteria defined in these instructions.
Verify that a formal Rescue Plan is in place. Inspect the system per the 'User' inspection points defined in the "Inspection
and Maintenance Log" (Table 2). If inspection reveals an unsafe or defective condition, or if there is any doubt about its
condition for safe use, remove the system from service immediately. Clearly tag the system "DO NOT USE". See Section 5
for more information.
5.0 INSPECTION
;
After product has been removed from service, it may not be returned to service until a Competent Person confirms
in writing that it is acceptable to do so.
5.1 INSPECTION FREQUENCY: The system must be inspected at the intervals defined in Section 1. Inspection procedures
are described in the "Inspection and Maintenance Log". Inspect all other components of the Fall Protection System per the
frequencies and procedures defined in the manufacturer's instructions.
5.2 DEFECTS: If the system cannot be returned to service because of an existing defect or unsafe condition, then either
destroy the system or contact 3M or a 3M-authorized service center about possible repair.
5.3 PRODUCT LIFE: The functional life of the Fall Arrest system is determined by work conditions and maintenance. As long
as the product passes inspection criteria, it may remain in service.
6.0 MAINTENANCE, SERVICING, STORAGE
6.1 CLEANING: Periodically clean the metal components of the System with a soft brush, warm water, and a mild soap
solution. Ensure parts are thoroughly rinsed with clean water.
6.2 SERVICE: Only 3M or parties authorized in writing by 3M may make repairs to this equipment. If the System has been
subject to fall force or inspection reveals an unsafe or defective conditions, remove the system from service and contact
3M regarding replacement or repair.
