ABSTRACT:
An open-topped vehicle body, such as a dump body, includes a tarping system that is deployed over the body by a pivoting bail member. An actuation mechanism applies a torque to the bail member to automatically pivot the member and deploy the tarp cover. The actuation mechanism includes a number of double coil spiral torsion springs anchored on a shaft attached to the dump body. The springs each include a right and a left coil portion concentrically wound about an integral center anchor portion. The shaft includes an elongated slot to receive and support the center anchor portion of each spring within the mechanism. The actuation mechanism includes a housing attached to the bail member. The housing contains the double coil springs and supports a pair of reaction posts extending therethrough. The coil portions of each spring include a left and right reaction end configured to contact and provide a torsional force against a corresponding reaction post within the housing.
