NOTE

OTH Single Point Davit Tests are conducted with independent test weights or water bag. The boat is NOT used. The Contractor shall provide water bag.

3.7 No Load Testing. Conduct an operation test of the SPD with no load. Ensure all safety features operate properly. Test the davit through the entire range of motion. Adjust the Two-Block limit switch and verify that it shuts down the equipment.

3.8 Static Testing. Test the static strength of the SPD by attaching 8,550 lbs of Contractor furnished weights (or water bag) to the hook. Ensure that the weight will not strike the cutter or damage it in any way. Hold the weight for at least 10 minutes in this condition. No visually observable creep/slip shall be allowed. The Contractor shall provide 8,550 lbs test weight.

3.8.1 Use a crane to place the weight on the davit hook. It will not bear weight during testing, but shall remain on the hook for the duration of the static weight test. Upon the completion of static test, remove all weights

3.8.2 Post Test Inspection. Following each test, an inspection shall be made in the presence of the Coast Guard Inspector to ensure that no parts have been strained and to verify that all parts are in proper condition. Typical defects to look for are:

3.9 Dynamic Testing. After successful static testing, operationally test the SPD to 125 percent of hoisting capacity (7125 lbs). Ensure that the Contractor furnished weight will not strike the cutter or damage it in any way. Check winch for rated speed at rated load and check rated hydraulic oil flow and pressure in accordance with the manufacturer recommendation.

NOTE

7125 lbs is the maximum operational test load for the 5700CT SPD.

3.9.1 Test the winch operation by raising and lowering the weight. Raise and lower the weight through at least 3 cycles. Ensure wire rope reeves fair on the winch drum and all mechanisms are set properly.

4. NOTES

The Coast Guard Availability Project Manager (APM) and cutter shall complete the following Maintenance Procedure Cards (MPC) associated with this install upon completion of this work item:

· A-C-10383, Test Davit Hook (Depot)

· A-M-50, Lubricate/Inspect Single Point Davit (Org)

· A-S-81, Check Single Point Davit Oil Levels (Org)

· A-S-87, Inspect Single Point Davit (Org)

Single Point Davit Constant Tension Testing Procedures as Presented by Technicians from Allied Systems

Step 1: Energize the davit and lower the hook to an appropriate height to be tied.

Step 2: Tie the hook to a fixed point on the deck.

· Recommend using triple braid nylon line with a taught-line hitch.

· Ensure that the line goes through the handle of the davit’s hook.

· Ensure that the wire rope is as vertical as possible.

· SHERMAN used the tying system pictured below to accomplish the requirements above.

Step 3: Using the winch controls, reel in the cable until there is sufficient tension in the line so that the tension indicator engages (pictured below).

Step 4: Press the Constant Tension (CT) button.

· At this point the indicator light should illuminate indicating that CT is on.

· Although CT has been selected it should not fully engage yet.

Step 5: Using the winch, slack the line until the tension indicator disengages.

· At this point CT should be engaged.

Step 6: Have someone physically pull down on the cable.

· When CT is properly set to its minimum tension setting, someone should be able to pull out the cable with about 50lbs of force.

· If the above does not work, then either constant tension is not working or the minimum tension is not properly set. In the consol there is a small potentiometer that can be adjusted to correct the minimum tension.

· From that point, you should be able to adjust the tension from the winch control joystick.
