Motion-stabilized crane systems and associated methods

A motion-stabilized crane system for lifting a load, the crane system comprising:

• a crane base extending from a first end to a second end opposite the first end;
• a crane boom having a first end pivotably coupled to the second end of the crane base and a second end opposite the first end;
• a hoisting cable supported by the crane boom;
• a hook suspended from the hoisting cable of the crane system;
• a motion stabilizer pivotably coupled to the second end of the crane boom, the motion stabilizer comprising:
• a hook housing in which at least one of the hoisting cable and the hook is received;
• a linear actuator coupled to the hook housing and configured to rotate the hook housing about a first axis in response to the activation of the linear actuator;
• an optical sensor coupled to the hook housing and configured to capture as a sensor output associated with the position of at least one of the hook and the hoisting cable in the hook housing;
• and
• a stabilizer control module configured to activate the linear actuator to counteract an uncontrolled motion of at least one of the hook and the hoisting cable based on the senor output produced by the optical sensor.

A motion stabilizer for a crane system, the motion stabilizer comprising:

• a hook housing configured to receive at least one of a hoisting cable and a hook of the crane system;
• a linear actuator coupled to the hook housing and configured to rotate the hook housing about a first axis in response to the activation of the linear actuator;
• a sensor coupled to the hook housing and configured to capture as a sensor output associated with the position of at least one of the hook and the hoisting cable of the crane system in the hook housing when the motion stabilizer is coupled to a crane boom of the crane system;
• and
• a stabilizer control module configured to activate the linear actuator to reduce an angle formed between at least one of the hook and the hoisting cable and a vertical axis based on the senor output produced by the sensor.
