  • Patent number: 7374126
    Abstract: A cable guide of a cable winch, such as a cable hoisting winch, includes a cable drum having at least one cable groove and a cable guide having at least two base segments expanding into a ring. The two base segments are guided in the cable groove by at least one engaging element and are supported against the cable winch by at least one torque support. Elements for guiding and holding down a cable are arranged on the base segments. To create a simplified and optionally modular design of a cable guide, the base segments may be configured such that at least one torque support and at least one add-on element for guiding and holding down a cable can be secured in a desired arrangement on the base segments.
