Operating The Warping Drum Independently - Maxwell 6000 Series Manual

disengage it. If there is too much slack in the
chain, it might be necessary to remove the domed
nut from the end of lead screw and release the
screw completely. If doing that, make sure the
band brake and clutch is still engaged, for safety
reasons.
• Fully disengage the clutch by turning the clutch
nut anticlockwise until it comes to a stop.
• Slowly release the band brake in a controlled
manner. The chain should now release, the
weight of self-launching anchor being sufficient to
draw out the chain. Regulate the chain speed by
gradually engaging/disengaging the band brake.
• When the required amount of chain is out, tighten
the band brake and engage the chain stopper.
• If the band brake is not fitted, the speed of chain
can be controlled by the clutch. In that case, after
disengaging the chain stopper, slowly release the
clutch by inserting the lever into the clutch nut
and turning it anti-clockwise. Regulate the chain
speed by gradually engaging/disengaging the
clutch.

OPERATING THE WARPING DRUM INDEPENDENTLY

3.5
This is applicable to VW and VWC models only.
The drum can be operated independently of the
chainwheel and can be used to manage docking
lines or a second anchor. To use in this way, proceed
as follows:
• Engage the chain stopper, the pawl or the band
brake (whichever is fitted).
• Fully disengage the clutch as described in
Section 3.4.
The drum may now be operated independently of
the chainwheel. Maxwell recommends all warping
operations be controlled by the footswitch. This
makes it a one-person operation and offers better
control of the capstan in case of emergency.
Take several turns of the warping line around the
drum and pull on the rope tail with sufficient manual
force to provide good grip of the line to the drum,
whilst operating the footswitch. Make sure the drum is
operated in the same direction as the line is wrapped
around it.
Do not engage more turns on the drum than are
necessary to accomplish the task. Whilst docking,
wind and tide can impose sudden and excessive line
tension. It is recommended to allow slipping to occur
at the drum. This will protect the capstan, docking
lines and vessel from damage.

It is considered potentially dangerous to allow
the chain to free fall in an unrestricted manner
- always control the chain speed.
Picture 3.2
Chain Roller-Stopper-Tensioner
The chain slack between the tensioner and
the windlass should be kept to less than the
end travel of the tensioner. This allows for safe
disengagement of the tensioner and transfer of
load to the chainwheel.
While handling docking lines with the capstan,
ensure everyone stays well clear of the lines
and the capstan.
Take care not to allow "riding turns". This is
caused by the loaded line climbing on top of
lower loaded coils on the drum. A riding turn
can only be removed by paying the line out to
the point where the riding turn is created.
