Removal Instructions
1. Push inward on the capstan and rotate it counterclockwise.
2. Align the capstan’s slots with the shaft’s pins and pull off.
!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.
3. Clean the capstan and properly store it. Failure to properly store and handle the cap-
stan will result in premature wear and failure.
Capstan Calibration
The calibration of the Slip Clutch Capstan should be verified periodically to ensure proper
capstan operation (See Section 4A). Frequency of verification depends on frequency and
severity of use.
It is recommended that the Condux Slip Clutch Capstan be recalibrated and repaired at
the Condux facility in Mankato, Minnesota. See Section 10B for details on returning the
capstan to Condux International for calibration.
If it is not possible to return the capstan back to Condux International for calibration, it can
be field calibrated following the instructions in this section (See Section 4B). However, if
the capstan is field calibrated, Condux assumes no liability for incorrectly calibrated cap-
stans resulting in damaged cable. If the factory supplied safety wire has been removed,
the capstan will be considered to have been field calibrated and all warranties, implied,
written or otherwise portrayed are considered null and void.
A. vERIFY THE CAPSTAN CALIBRATION SETTING
1. Set up the capstan on a bayonet shaft as if cable were to be pulled (figure 3).
2. Place a pull line around the capstan. The pull strength of the pull line must exceed the
1,000 pound capacity of the capstan.
3. Attach the pull line to a load indicator such as a Dillon Dynamometer, Available from
Condux International (See Section 6).
4. Slowly apply pressure to the capstan to tighten the pull line. Continue to pull slowly until
the capstan begins to slip. The value shown on the dynamometer will be the force at
which the capstan is calibrated to slip. If the value shown is not the required slipping
force, the capstan will have to be recalibrated (See Section 4B).
