ABSTRACT:
An apparatus is provided for use at an airport for drawing in and paying out an electric cable, which reliably grips the cable even when it is covered with a slippery anti-freeze fluid used at airports. The apparatus includes a motor-driven traction wheel against which the cable is pressed, with the periphery of the wheel being concave and having a radius of curvature about the same as the cable so the cable can closely nest in it. The wheel has closely spaced treads that press through fluid on the cable to grip it, and has a circumferentially extending groove through which fluid can drain. The cable is pressed against the wheel by rollers that have concave peripheries to also closely surround the cable.
