Abstract
A rope condition assessment system for assessing a condition of a rope is disclosed. The system comprises, a frame defining a passage for receiving a rope to be evaluated, one or more acoustic transducers supported by the frame about the passage, and a controller configured to: control the one or more acoustic transducers to generate an acoustic signal for propagation across the passage, and detect the acoustic signal following propagation of the acoustic signal across the passage, and evaluate a characteristic of the detected acoustic signal.
Claims (18)
1. A rope condition assessment system for assessing a condition of a rope, the system comprising: a frame defining a passage for receiving a rope to be evaluated, one or more acoustic transducers supported by the frame about the passage, and a controller configured to: control the one or more acoustic transducers to generate an acoustic signal for propagation across the passage, and detect the acoustic signal following propagation of the acoustic signal across the passage, and evaluate a characteristic of the detected acoustic signal.
2. A system as claimed in claim 1, wherein the controller is further configured to infer a characteristic of the rope based on the evaluated characteristic of the detected acoustic signal.
3. A system as claimed in claim 2, wherein the controller is configured to infer the characteristic of the rope by comparison of the evaluated characteristic of the detected signal to reference data stored in machine-readable memory associating the characteristic of the rope with the evaluated characteristic of the detected acoustic signal.
4. A system as claimed in any one of claims 1 to 3, wherein the controlling the one or more acoustic transducers comprises controlling the one or more acoustic transducers to detect a reflected component of the acoustic signal.
