Device for locking an object suspended on a cable

A locking device for locking an object suspended from a cable, the device comprising a cable and a clamp, the cable passing through the clamp and extending along a substantially vertical axis, the clamp comprising:

• a fixed part connected to the object, at least two moving jaws, a first actuator and a second actuator, the two jaws being capable of translational movement relative to one another in a direction perpendicular to the axis of the cable, the two jaws coming into contact with the cable to immobilize the cable by clamping in a closed position and moving away from the cable in an open position, the fixed part having as many inclined surfaces as there are jaws, the inclined surfaces being inclined with respect to the axis of the cable so as to move closer to the axis of the cable toward the top, each of the jaws being configured to slide along one of the inclined surfaces allowing the jaws to pass from the open position to the closed position, the clamp further comprising elastic elements configured to move the jaws away from the cable, the first actuator being configured to move the jaws upward, to slide each of the jaws along one of the inclined surfaces and allow the clamp to close, the second actuator being configured to pull downward on the cable with respect to the fixed part and allow the clamp to open.
