Gantry crane rope kink

Gantry crane rope in the local distortions resulting from the permanent deformation is called rope kinks.overhead bridge crane Twisted rope rotation direction consistent with the known positive kink, otherwise known as negative kinks. General Steel with rotation resistance, if the end of the strand tension is applied without tying it, then pour the strands twist to the direction of rotation, which is caused by internal factors rope kink.overhead gantry crane Wire rope kink, after repeatedly lifting under load, and only partially exposed cord, generally do not have the phenomenon of broken wires. However, tests showed that the strength after injury wire rope kink will be significantly reduced. Being kinked strength is only 60% of the original strength 80% less than the intensity of the negative twist to 50% of original strength.hoist gantry crane Severe intensity will be reduced to only the original 10% to 20%.
