Abstract
Actuations systems in which pulley systems may be used as redundant (back-up) mechanisms are described. The systems provide mechanical advantage, especially useful when manual input is required to deploy a back-up mechanism. A pulley may be integrated into a clevis, a cable routed about the pulley, and one end of the cable made stationary, causing the pulley to counterbalance approximately twice the input force provided.
