The object of the invention is a cable winch with automatically controlled regulation of speed of unwinding of a haulage cable. The cable winch of the invention is used as a drive unit of a device for haulage of timber on a poorly accessible terrain. The cable winch of the invention also provides for a remote control of the cable winch and based on the speed of the carriage (10) the brake force of the cable winch can be controlled by a brake (3) that acts via a braking cylinder (4) on the speed of unwinding of a drum (2) with a haulage cable (6) by means of an electronic circuit (7), in which a comparison between a desired value of speed of the carriage (10) and the actual speed measured by a sensor (1) on a pulley (11), an estimate of terrain inclination and that of load mass on the carriage (10) is made possible.
