Abstract

A system to monitor and analyze a multi-strand rope includes a rope data sensor to collect data regarding the physical state of the rope; one or more usage sensors to collect data regarding the usage of the rope; a position measurement device to measure the position of the rope; and a computer system connected to the rope data sensor, the one or more usage sensors and the position measurement device to correlate the collected data and position measurement to give real-time data on the status of the rope at one or more sections.

First claim

The invention claimed is:

1. A system to monitor and analyze a multi-strand rope, the system comprising:
a rope data sensor to collect data regarding the physical state of the rope;
one or more usage sensors to collect data regarding the usage of the rope;
a position measurement device to measure the position of the rope; and

a computer system connected to the rope data sensor, the one or more usage sensors and the position measurement device to correlate the collected data and position measurement to give real-time data on the status of the rope at one or more sections.

2. The system of claim 1 , wherein the computer system comprises
one or more processors and/or databases for storing and/or processing data.

3. The system of claim 1 , wherein the rope data sensor senses one or more of the cross-sectional area of the rope and the volume of the rope.

4. The system of claim 1 , wherein the data regarding the usage of the rope includes one or more of the following: bending of the rope, tension in the rope, temperature of the rope, diameter of the rope, shape of the rope, elongation and creep of the rope.

5. The system of claim 1 , wherein the position measurement device is a measuring wheel or a contactless measuring system.

6. The system of claim 1 , wherein the computer system uses the data and the status to predict a failure of at least a section of the rope.

7. The system of claim 1 , wherein the computer system uses the data and the status to plan maintenance for at least a section of the rope.

8. The system of claim 1 , wherein the one or more usage sensors comprises a temperature sensor, a load sensor, a bending sensor, a speed sensor, a position sensor and/or a diameter sensor.

9. The system of claim 2 , wherein the database includes information regarding the historic usage, the historic state and/or the current state for one or more sections of the rope.

10. The system of claim 1 , wherein the rope is a wire rope.

11. The system of claim 1 , wherein the rope is a fiber rope.

12. The system of claim 1 , wherein the computer system comprises a user interface.

13. The system of claim 1 , wherein the computer system comprises a data input for inputting data into system.

14. A method for real-time monitoring and analysis of a rope, the method comprising:
measuring and collecting physical property data for the rope;
measuring and collecting usage data for the rope;
measuring the position of the rope; and
correlating the physical property data, the usage data and the position to give a real-time measurement of the status and event history of the rope at one or more sections of the rope.

15. The method of claim 14 , wherein the step of measuring and collecting physical property data for the rope comprises:
measuring and collecting cross-sectional area data for the rope.

16. The method of claim 14 , wherein the step of measuring and collecting usage data for the rope comprises:
using one or more sensors to measure and collect data related to one or more of the following:
bending of the rope, tension in the rope, temperature of the rope, speed of the rope, elongation or creep of the rope, diameter of the rope and shape of the rope.

17. The method of any of claim 14 , and further comprising:
storing and/or processing the data in a computer system.

18. The method of any of claim 14 , and further comprising:
predicting when at least a section of the rope will fail based on the physical property data, the usage data and position.

19. The method of claim 18 , wherein the step of predicting when at least a section of the rope will fail based on the physical property data, the usage data and position comprises:
comparing the physical property data for the rope with a predetermined failure threshold; and
predicting when this threshold will be reached based on collected usage data and physical property data.

20. The method of claim 14 , and further comprising:
using the data collected, stored and/or input to form an algorithm which integrates and plots the collected, stored and/or input data as a single value for one or more rope sections.
