Fatigue life determination method for elevator wire rope
To determine fatigue life, a special wire rope fatigue testing machine is required, in accordance with the national standard GB/T12347-2008 wire rope bending fatigue test method, or YB/T4288-2012 elevator wire rope bending fatigue test method. The quality of elevator wire ropes from different manufacturers can be compared, and the comprehensive quality of elevator wire ropes with different production processes can also be compared.
The manganese phosphating coated elevator wire rope and the smooth elevator wire rope of the same diameter, structure and performance are tested on a fatigue testing machine until the first broken strand appears, the fatigue life is recorded, and then the test data is compared. Generally speaking, the longer the fatigue life, the longer the service life, and they are in direct proportion. The longer the fatigue life, the higher the overall quality of the elevator wire rope.
