6.6.12 Check that the auxiliary hoist is functioning properly
Slewing direction Check the slewing direction before laying on the hoist rope.
Ask someone to observe the slewing direction for you, or stand next to the
auxiliary hoist and use the hand-held control.
• Remove the rope end fitting (1) from the
clamp (2).
• Slowly perform the Lift and Lower move-
ments – stop the movement as soon as the
hoist drum turns.
• Check that the slewing direction is correct:
If the slewing direction is incorrect
• Check whether the hydraulic hoses have
been mistakenly connected;
à p. 6 - 61.
Slewing indicator Check the function of the slewing indicator when applying the hoist rope.
• You must feel a pulse on the slewing indicator (1) when the auxiliary hoist
is rotating.
• If no pulse is present, contact Manitowoc Crane Care.
G
Risk of accidents due to incorrect slewing direction
Check after each installation that the slewing direction is correct.
This prevents accidents caused by the hoist rope winding up unexpectedly
when it is applied.
G
Danger due to slack rope!
Only drive the auxiliary hoist briefly and at the lowest speed.
This prevents slack rope from being created, or the rope end fitting being
pulled into the hoisting gear frame.
