Cable, cable manufacturing method, monitoring system and crane

The invention discloses a cable, a cable manufacturing method, a monitoring system and a crane. The cable comprises a shielding layer and a plurality of first conductors arranged in the shielding layer. The first conductors are used for power supply and signal transmission; the first conductor comprises a plurality of metal wires and an inner insulating sheath arranged at the peripheries of all the metal wires; wherein a plurality of metal wires are twisted to form a wire bundle, and each metal wire is provided with at least three twisting points within the length range of 2.5 mm-3. 5mm of the wire bundle. According to the utility model, the intertwisting and weaving density of the metal wires is increased, the tensile strength of the wire bundle is improved on the premise of ensuring that the wire bundle has certain bending flexibility, and each bundle of first conductors can better share the load when being stressed, so that the overall mechanical property and durability of the cable are improved; and meanw
