the hoisting distance remaining; this
distance must be great enough to allow
the operator and the lockout system, if
installed, to prevent a two-block event. If
necessary, add chain between the sensor
and weight to increase warning distance.
If still insufficient, contact your service
representative.
2. Chain length adjustment № 2 – maximum boom
angle
a. Raise the boom to the maximum angle.
b. Hoist slowly as described in Step 1.b. Verify
that the warning distance is equal to or
greater than that determined at the
minimum boom angle.
3. Chain length adjustment № 3 – speed test:
Lower the boom until the weight height
becomes visually clear to the operator.
Repeatedly create two-block, progressively
hoisting faster, to ensure that the warning and
lockout work within acceptable amount of time
and distance. Increase the length of the chain if
needed.
