Abstract
A winch constructed with a fairlead frame providing a mounting base for the winch and providing a rotational support for a cable drum. Loads exerted on a cable and through the fairlead rollers and cable drum are transferred to the unitary fairlead frame members, and thus to the base to which the winch is mounted.

A winch, comprising:
- a cable drum rotatable for winding and unwinding a cable therefrom;
- a fairlead frame including spaced-apart frame members, each said fairlead frame member being a unitary piece of material and adapted for journaled rotation of said cable drum therein, wherein cable loads exerted on said cable drum are transferred to said fairlead frame members;
- and
- said fairlead frame members each having a first edge with a flange for mounting the winch to another anchor structure and a second different edge of each fairlead frame member for supporting a cable guide with an opening therein for routing the cable onto said cable drum.
