Abstract

See full text

There is described a hoisting system and method of lifting that make use of a particular fibre rope. The fibre rope includes a plurality of magnets that are embedded within the fibre rope and spaced apart along the rope with a known axial distance between the magnets. The system may include a fibre rope hoisting speed sensor, and

    a magnetic field sensor that can sense the presence of the magnetic field of the embedded magnets. Using the sensors, the hoisting speed of the rope may be determined by: measuring the time between the passing of consecutive magnets by using the magnetic field sensor; calculating the distance between consecutive magnets using the hoisting speed sensor and the measured time between the passing of the consecutive magnets; and comparing the calculated distance between the magnets with an original, predefined distance between the magnets.
