Condux Slip Clutch Capstan - Manual (Page 3)

General Information
1.
The Condux Slip Clutch Capstan is intended to protect fiber optic or coaxial cable from
being over stressed during the pulling operation. When the preset load is reached, an
internal clutch will disengage, stopping the capstan from rotating and protecting the cable.
Care should be taken so the capstan is not run while slipping for extended periods of time.
The Condux Slip Clutch Capstan is available in 30IN (762mm), 42IN (1067mm), or 50IN
(1270mm) diameters. Calibrated loads are available from 200 LBS (890 N) to 1000 LBS
(4448 N), Consult the Condux Factory, the Condux Catalog or web site (www.condux.com)
for more information.
The capstan is designed for use with a 2 7 ⁄
16
inch (62 mm) diameter, AT&T specification
bayonet style power take-off (PTO) shaft. The Slip Clutch Capstan is meant to be used
with synthetic pulling ropes or measuring tapes. Do not use steel wire or wire rope on the
Slip Clutch Capstan.
!NOTE: Slip clutch brake pad material contains no asbestos.
It is required that the operator be properly trained to use the PTO on the truck before using
this product.
Installation Instructions
1. Attach the capstan to the drive shaft by aligning the capstan’s slots with the shaft’s
pins. Push the capstan onto the shaft until it stops, then rotate clockwise until it stops.
Pull outward to lock the capstan into
position. Make sure the shaft locking pins are visible through the holes in the
capstan hub.
!CAUTION: HEAvY OBJECT - Use Two Person Lift. The 42IN and 50IN
Slip Clutch Capstans are heavy and require two person lift and proper
techniques to avoid personal injury.
2. Move the power source with drive shaft and capstan into its final position. The pull line
will wrap best on the capstan if the capstan is angled about 10° away from the pull line
(figure 1). This will allow the line to walk down the side of the capstan and push the
previous wraps to the side.
