The Deep Logging Winch is a marine winch that has been modified for polar field use. The winch is capable of logging boreholes 4000 meters deep and can operate at temperatures as low as -45 degrees C. The winch allows full-range speed control down to a complete stop, and can maintain a uniform speed from 1cm/s to 60cm/s. The winch includes a digital depth measuring system with a precision of 1 cm or better, and a cable-tension measuring system. The winch allows for automatic re-spooling of the cable via a level-wind system. The cable is a standard four-conductor logging cable headed with a standard 1-inch outer-diameter Gearhart-Owen variant. The winch has a broadband slip-ring connector enabling it to transmit both analog and high speed digital signals from DC to ~10 MHz.
A casing-mounted logging tower is available for use with the Deep Logging Winch.
