Testing device for wire rope tension of hoisting steel wire rope

The invention relates to a testing device for the wire rope tension of a hoisting steel wire rope. The testing device comprises a supporting frame. A head sheave which allows a hoisting steel wire rope to be tested to roll and pass is arranged on the top of the supporting frame. A locating seat connected with the first end of the hoisting steel wire rope to be tested is arranged on the supporting frame. A rolling cylinder for applying traction acting force on the second end of the hoisting steel wire rope to be tested is further arranged on the supporting frame. The actual using working condition of the hoisting steel wire rope is simulated by using the rolling cylinder, the supporting frame, the head sheave and the locating seat of the test device, when in testing, a corresponding optical grating type fiber optic sensor is equipped to test the corresponding wire rope tension, key technical parameters such as the tension variable quantity of the wire ropes, total tension and the friction moment of the hoistin
