Abstract
A compact capstan includes a drum, a coupled hub, a passage extending through the drum and hub, and a shaft extending through the drum and hub. The shaft engages the passage such that the shaft can transmit a torsional force to the drum and the hub which are free to move along the length of the shaft. The drum includes a spiral groove to receive a cable loop wound around the drum. The hub has a thread with substantially the same pitch as the spiral groove to engage a threaded support such that the hub and the drum move laterally along their length relative to the threaded support as the hub and the drum are rotated. The shaft has a length that is substantially greater than the passage such that the shaft extends beyond both ends of the passage.
