Condux Winch Line Blower System - Manual (Page 13)

CONDUX WINCH LINE BLOWER 11
Note: One person should be in charge of the control valve assembly and, if positioned properly,
should be able to view the winch line feeding off the winch drum, view the cable feeding down
into the utility service access vault around the sheave, blocks, etc., and monitor the condition of
the winch while it is being propelled. A second person should assist in monitoring the winch line
and keep in contract with the exit utility service access vault. Two-way radios are recommended
so the personnel at each end of the conduit run can be aware of the situation status immediately.
Figure 11: SLOWLY OPEN CONTROL VALVE
3. Open the outlet valve on the air compressor See Figure 11.
4. Slowly open the winch line blower control valve assembly. The control valve
assembly can be slowly opened by turning the valve handle in line with the air flow.
The missile will begin to move forward towards the exit utility service access vault,
pulling the winch line with it. Allow all slack to come out of the winch line before
opening the valve fully. Continue opening the control valve while constantly
monitoring the status of the winch line.
