! CAUTION
Never use a lever or a wrench to tighten the auxiliary brake. Damage to the mechanism will
occur.
NOTE
A force of about 25 lbs on the handwheel is usually sufficient to provide enough friction on the
band to hold the drum.
7.
Tighten the auxiliary brake (figure 7, item 3) by turning the auxiliary brake handwheel (figure 7, item 4).
8.
Perform the desired Towing Machine Operation HEAVE or PAYOUT MODE procedure in this work package.
TOWING MACHINE OPERATION SPOOLING DEVICE ALIGNMENT
NOTE
For tight spooling, the rollers should have a slight lead on the previous wrap. This is more
important during respooling than paying out.
1.
During all heave and payout operations, observe the spooling device alignment to make sure the wire rope is passing
through the rollers more or less perpendicular to the drum and in line with the previous wrap.
WARNING
Do not disengage the clutch if there is heavy quartering load on the towline as the towline
may drive the handwheel at rapid speed until spooling rollers align themselves with wire
rope. Always make sure there is a light line pull or small misalignment before disengaging
the clutch. Rapidly turning the handwheel could cause personal injury.
2.
If the spooling device is not properly aligned to the towline, realign the spooling device by pulling OUT on the spooling
device handwheel (figure 12, item 1) and turning it in the desired direction.
3.
After realigning the spooling device, push IN on the spooling device handwheel (figure 12, item 1) to engage it in the
drive.
