ABSTRACT:
An actuation mechanism for a tarping system includes a double coil spring mountable on a pivot shaft of the mechanism. A bushing is mounted on the pivot shaft and within the double coil spring. The bushing includes an eccentric external periphery that limits the deflection of the spring, particularly at the transition points between the center portion and each of the coil portions of the spring. As the spring winds or coils, the coil portions progressively contact the eccentric periphery of the bushing to not only limit further movement of the coil portions, but also to provide support for those portions under load.
