US Patent 9849982 Rescue hoist end-effector

An end-effector for a hoist includes a drive and an articulating arm. The articulating arm includes support disks, control cables extending through the support disks, and a hoist cable extending through the support disks. The drive includes an actuator connected to one of the control cables. The actuator deploys and retracts the control cables, thereby displacing the articulating arm from an end-effector axis. The drive also includes a stabilizer mounted on a drive housing, the stabilizer generates a stabilizing moment in response to the articulating arm displacing from the end-effector axis.
