Abstract (en)
[origin: WO8701776A1] A lock device capable of supporting a load is given whereby a first threaded member (3) cooperating with a high lead angle second threaded member (12) is provided to control linear movement parallel to the axis of the threaded members. The high lead angle is sufficient to be backdriving or non self-locking. A first brake (14) opposing relative rotation of the threaded components is provided and a second brake (19, 22) having a surface concentric with the axis of the threaded members and contacting at least one threaded member to lock said members to preclude linear movement is also provided. The second threaded member (12) cooperates with the first threaded member (3) to carry the load when the system is locked. An actuator (20) is provided to selectively maintain the second brake in a substantially inoperative mode.
