ANCHOR WINDLASS POWERED WILDCAT OPERATION
GENERAL
1.
Wildcats can be operated together or separately as dictated by the torque limitations and the load. Each wildcat is
equipped with a dog clutch and a hand brake. Engaging the dog clutch and releasing the brake allows the wildcat to be
driven in a direction and at a speed set by the appropriate controls.
2.
For normal speeds and loads, the two-speed lever will be in the HIGH SPEED position. The chain can be lowered or
raised at a variable speed from creep to approximately 25 ft/min (7.9 m/min). For heavy loads, the two-speed lever
should be in the LOW SPEED position. The LOW SPEED mode doubles the torque and allows the chain to be lowered
or raised at variable speeds, from creep to approximately 12 ft/min (3.8 m/min).
OPERATION
1.
Perform the Anchor Windlass Pre-Operation procedure in this work package.
2.
Engage the dog clutch (figure 1, item 6) by performing the following steps:
a.
Remove the dog clutch tool from the frame-mounted bracket.
b.
Loosen both wing nuts (figure 1, item 7) on the face of the shifter ring (figure 1, item 8).
! CAUTION
Maneuvering the main shaft may be necessary (with the brake set) to engage the dogs with the
clutch jaws on the wildcat. Attempting to engage dogs and clutch jaws when not properly aligned
could damage the windlass.
c.
Verify that the anchor windlass brake (figure 1, item 4) is set by rotating the anchor windlass brake handwheel
(figure 1, item 5) fully clockwise.
d.
Verify that the pelican hooks (figure 1, item 1) are secured to the anchor chain (figure 1, item 2) and that the pelican
hook turnbuckles (figure 1, item 3) are tight.
e.
Set the two-speed control lever (figure 2, item 1) to LOW SPEED.
f.
Operate the RAISE-LOWER control (figure 2, item 2) until the slots in the dog clutch (figure 1, item 6) are aligned
with the slots in the shifter ring (figure 1, item 8).
g.
Insert the dog clutch tool in the nearest slot that is aligned with the dog clutch (figure 1, item 6) and the shifter ring
(figure 1, item 8).
NOTE
A 50-degree movement of the clutch shifter ring is required to fully engage or disengage the dog
clutch.
h.
Push the dog clutch tool forward to engage the dog clutch (figure 1, item 6).
i.
Tighten both wing nuts (figure 1, item 7) on the face of the shifter ring (figure 1, item 8).
3.
Select the desired speed by setting the two-speed control lever (figure 2, item 1) to the desired speed.
