DESCRIPTION
- The conversion kit contains all the parts required to convert a CW 800 E cap-stan winch purchased before October 2025 to the technical standard of the CW 800 E – Model 2025, thereby benefiting from the improved functions. The conversion takes around 20 minutes, and detailed instructions are included. Both capstan heads have been widened in the new CW 800 E model 2025. The rope wrapping area on the Ø 55 capstan head has been increased from 8.5 cm to 10.5 cm, and on the Ø 110 capstan head from 6.5 cm to 8.5 cm. In addition, a knurled surface has been integrated at the end of the caps-tans, which increases friction and reduces the pulling force required by the operator. The maximum pulling load remains unchanged at 400 kg and 800 k,g respectively.
- The rope guide jaws have also been redesigned. They now surround threspectiveve capstan head, ensuring better rope guidance and significantly less rope wear.
- Due to the redesign, the rope entry and rope exit also had to be renewed. The corresponding parts are included.
