15-12.1.3 Controlling a runaway discharge hose. If a winch runaway situation develops, control runaway as follows:
a.
Barge 1 - Position winch control lever in NEUTRAL.
b.
Barges 2 and 3 - Push disc brake lever to ON.
c.
If this fails to stop runaway, apply band brake as follows:
(1)
Open valve SD3.
(2)
Obtain BAND BRAKE PUMP HANDLE from stowed position and insert in pump extension.
CAUTION
While pumping, do not exceed 4,000 psi as shown on BAND BRAKE PRESSURE
gauge.
(3)
Pump until band brake piston enters cylinder, band is tight on the brake drum and stops rotation.
(4)
Position valve to neutral position (midway between OPEN and CLOSE position) to lock the
cylinder in the set position.
(5)
If band brake begins to smoke, spray it with salt or fresh water to cool brake.
(6)
After band brake cools, close valve SD3.
(7)
Pump until band brake piston comes out of the cylinder and there is a slight clearance between
the band brake material and brake drum.
(8)
Remove pump handle and return to stowed position.
