3.0 INSTALLATION
3.1 PLANNING: Plan your fall protection system prior to use and installation of the Confined Space HC Davit Assembly.
Account for all factors that may affect your safety before, during and after a fall.
;
Plan your work program before starting. Have the required people, equipment and procedures available to do the job.
;
Always work in teams. One person being raised or lowered and another person to pay out and reel in the line.
;
Wear appropriate protective gear such as a hard hat, safety glasses, protective shoes with slip resistant soles,
heavy gloves, protective clothing and a face mask.
;
Confined Space HC Davit Assembly mast extensions cannot be stacked. A maximum of one mast extension may be
used per davit base.
;
All winch and SRL mounting parts and hardware must be supplied or approved by 3M Fall Protection.
;
Securely anchor the winch before using.
;
System users must use an approved full body harness.
;
Use only retractable devices or energy absorbers with a maximum arrest force equal to or lower than the lowest
rated component of your system.
;
Retractable devices or energy absorbers must be installed and used in accordance with the manufacturer's
instructions.
;
Modular components are labeled with the capacities and rating to which they were designed, tested, and
manufactured. The rating of any system is considered to be the rating of the lowest rated component in the system. Do
not use equipment if rating labels are damaged or illegible. New labels are available from 3M Fall Protection.
;
The Confined Space HC Davit Assembly should be removed from the job site when no longer needed.
3.2 INSTALL THE CONFINED SPACE HC DAVIT ASSEMBLY:
1. (Figure 3) Insert the Confined Space HC Davit Assembly mast extension into an installed 3M HC davit base. (See Table
1 for 3M Base descriptions.) Follow davit base installation instructions for securing the davit base to the anchorage
structure.
2. Attach the davit head assembly to the universal assembly:
a. (Figure 4a) insert the davit head gusset tube (A) into the universal assembly gusset weldment (B). Use detent
pin (C) to secure the gusset tube in the gusset weldment.
b. (Figure 4b) Use the hitch pin (D) to attach the davit head arm tube between the side plates (E) of the universal
assembly. Secure the hitch pin with the lynch pin that is connected to the opposite side of the universal assembly.
3. (Figure 5) Place the assembled davit arm/universal on the mast extension. The bottom edge of the davit arm tube
must contact the ridge of the mast extension. Center the notch at the bottom of the davit arm tube on the screw
located on the ridge of the mast extension.
4. (Figure 6) The davit arm extension length can be adjusted to one of four positions. Remove detent pin (A) and slide
the davit arm extension out or in to reach the desired length. The davit arm must be secured at that extension
position with the detent pin (A). Fully insert the detent pin.
5. (Figure 7) The davit arm angle can be adjusted to one of three positions. Remove detent pin (C) and slide the gusset
tube (A) in or out of the gusset weldment (B). The gusset tube must be secured with the detent pin (C). Fully insert
the detent pin.
6. (Figure 8) Install the winch according to the manufacturer's instructions. The winch is mounted with the winch
bracket that is included with the universal assembly. The winch cable is typically routed over the rear pulley (A) on
the universal assembly and the top front pulley (B) on the Davit Arm. An alternate and/or additional front mounted
configuration is possible. See Section 3.3.
3.3 WINCH BRACKET 8000117:
1. (Figure 9) A front mounted winch or SRL can be added to the Confined Space HC Davit Assembly mast extension
by installing a second winch bracket 8000117 (purchased separately). Secure the winch bracket (A) to the mast
extension with the two winch bracket detent pins (B). The winch or SRL cable uses the front pulley (C) on the
universal assembly and the bottom front pulley (D) on the davit arm.
3.4 U-BRACKET ATTACHMENT POINTS:
(Figure 10) The two U-bracket attachment points (A and B) can be used for fall arrest, rescue, or material handling.
When using U-bracket attachment point A, do not exceed horizontal distance 38 cm (15 in) from the davit base.
4.0 USE
4.1 BEFORE EACH USE: Verify that your 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 Confined Space HC Davit Assembly per the 'User' inspection
points defined on the "Inspection and Maintenance Log" in this manual. 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.
5.0 INSPECTION
5.1 INSPECTION FREQUENCY: The Confined Space HC Davit Assembly 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.
