Adjusting/mounting hook operated hoist limit switch with weight ball
Adjust the geared limit switch, see
Adjusting the geared limit switch
section.
Press the UP button in the control pendant carefully.
Observe the hoisting movement until the operational hoist limit switch switches off in
the top hook position (B
).
If the hook operated hoist limit switch with weight ball is already mounted:
Keep the connecting rope taut.
Actuate the override button “S260” in the control box and the UP button on the control
pendant at the same time, until the emergency hoist limit switch switches off (A
).
Actuate the override button
“S261” in the control box and the DOWN button on the
control pendant at the same time to lower the hook by the dimension “x1” (see table
above) into position (C
).
If the ball has not yet been mounted:
Open the bolted connections (6).
Fit the ball (5) on the rope.
Tighten the bolted connections (6) to the prescribed tightening torque, see the
Tightening torques for screws
section.
If the ball has already been mounted:
Loosen the rope clamp on the connecting rope (4) to adjust.
Draw the connecting rope (4) through the ball (5) until the switch (1) is actuated.
Secure the connecting rope (4) with the rope clamp such that dimension “n” is
maintained.
Check whether dimension “m”
is maintained. If this is not the case, shorten the rope
at the wedge clamp (7).
If this is not possible:
Increase dimension “x1” and then check the switch
-off position, see Checking the
geared limit switch section
If necessary, adjust the geared limit switch, see Adjusting the geared limit switch
section.
If necessary, shorten the con
necting rope (4) such that dimension “n” is achieved.
