Adjusting the Slack Line Detector
1.8.1
ADJUST THE POSITION of the slack line detector valve every time the
wire rope take-off angle is changed, or when improper adjustment causes
lunging or incapability of lifting.
a
ELEVATE SLACK LINE DETECTOR ARM until it is at the angle where it
will be running with a taut wire rope. This can be accomplished by having a
helper physically lift the arm into position, or by applying a small load to the
wire rope to lift the arm.
b
LOOSEN THE SCREWS on the valve mount until the valve assembly will
rotate on the pivot pin.
c
ROTATE THE VALVE ASSEMBLY on the pivot pin until the valve roller is
centered in the detent slot of the slack line arm. See Figure 9.
d
MAINTAIN THE CORRECT DISTANCE between the roller wheel and the
arm. The valve should fully extend with the roller in the detent, and the valve
should fully retract if the roller is contacting the arm surface.
e
TIGHTEN THE SCREWS on the valve mount per recommended torque
sequence. See Figure 10.
f
TEST THE SLACK LINE DETECTOR adjustment by performing a very
short lift, and verify that it will descend smoothly. As the wire rope becomes
slack at the end of the lift, the valve should trigger the motor to halt and the
slack line indicator should activate.
g
REPEAT STEPS “a” through “g” if the slack line detector is not functioning
as intended.
Important!
• Always be sure that the slack line
detector valve is tightly attached
to the winch, and verify that it
functions properly before every lift.
• If slack line detector valve is not
properly adjusted, the valve could
prematurely halt the lowering
operation of the winch.
• Beware of moving parts and
pinch points any time a person
is within the swing radius of the
slack line detector arm.
• Always help the slack line
detector arm lift into running
position if it is in a downward
resting position. Failure to help
the lift the arm, could cause
the arm to snap up quickly, or
get pinched in the downward
position.
