3-3.2 Deployment of discharge hose (hose out)
WARNING
Make sure that nobody stands in front of or behind hose reel.
a.
Make sure steel chute surface is smooth and free of any irregularities that could damage hose.
NOTE
If hydraulic power unit Is shut down or no electric power Is available, deploy discharge hose
manually as given in paragraph 3-3.3.
b.
Release band brake on winch as follows:
(1)
Close valve SD3 (Figure 3-8).
(2)
Obtain band brake pump handle from stowed position and insert in pump extension.
WARNING
While pumping, do not exceed 4,000 psi as shown on band brake pressure gauge.
(3)
Pump until band brake piston comes out of cylinder and there is a slight clearance between band brake
material and brake drum.
(4)
Remove pump handle and return to stowed position.
c.
Screw on hose end cap.
d.
Deploy hose as follows:
(1)
On Barge 1 (Figure 3-1):
WARNING
During deployment on Barge 1, levelwind control lever must be operated.
Use care to regulate speed of levelwind movement with hose movement.
(a)
Use winch control lever to deploy hose end cap while using levelwind control lever to control
movement of levelwind.
(b)
Make sure hose end cap is pulled away from barge anchor lines to prevent entanglement.
(2)
On Barges 2 and 3 (Figure 3-2):
WARNING
During deployment on Barges 2 and 3, levelwind control lever must not be operated. Make sure
valve SD5 (Figure 3-9) on levelwind hydraulic drive motor Is OFF and levelwind moves freely.
(a)
Push winch disc brake lever (Figure 3-2) to OFF to release disc brake.
(b)
Use winch hose control lever to deploy pulling head assembly.
(c)
Make sure hose end cap assembly is launched away from barge anchor lines to prevent
entanglement.
WARNING
Barge winch deployment speeds and shore winch takeup speed must be the same but no faster
than 30 feet per minute. Deploying 2000 feet of hose normally takes 70-90 minutes.
(d)
Deploy hose at same speed that shore winch takes it in, but no faster than 30 feet per minute
Operate shore winch according to TM 55-1930-209-14&P-21. If a winch runaway situation start, to
develop, perform procedures in 3-3.3. Otherwise, go to step e.
