The invention discloses a steel wire rope pressing sleeve slippage test detection method and device. The device consists of a hydraulic pump, a digital display dynamometer, a power supply, an oil pressure pipeline, a steel wire rope pressing sleeve, a steel wire rope, a hollow jack load carrying ring and a hollow jack. The hollow jack is used for detection, the hollow jack must be placed between the hollow jack load carrying ring and the steel wire rope pressing sleeve before testing, digital display dynamometer parameters are set, pressure is continuously and slowly applied until the pressingsleeve generates slipping movement or pre-designed technical indexes, maximum pressurization force applied by the jack is immediately recorded, and the maximum pressurization force is a limit force value for the steel wire rope pressing sleeve to generate slippage; and pressurization stops until the steel wire rope pressing sleeve slides, and the maximum applied pressure value is recorded so as to detect a maximum force value for the steel wire rope pressing sleeve to move. The detection method is simple and easy in operation, can quickly and accurately measure the maximum slippage force which can be borne by the steel wire rope pressing sleeve, and avoids potential safety hazards when the steel wire rope pressing sleeve is used for the installation and use process of rigging, hangers andthe like.
