The invention discloses a double-steel-wire-rope lifting device tension adjusting system comprising two steel wire ropes which are arranged side by side and used for lifting. The double-steel-wire-rope lifting device tension adjusting system is characterized by further comprising a tension sensor, an adjusting hydraulic cylinder a switching-type electromagnetic control valve, an automatic oil supply device and a PLC (programmable logic controller), the tension sensor is arranged on the steel wire ropes, the adjusting hydraulic cylinder is arranged on the steel wire rope and connected with the switching-type electromagnetic control valve which is connected with the automatic oil supply device, and the PLC is connected with the tension sensor, the switching-type electromagnetic control valve and the automatic oil supply device respectively. A control principle of mechanical-hydraulic coupling is adopted, so that tension difference between the steel wire ropes can be detected in realtime, stability in running of a lifting system is controlled better, and the double-steel-wire-rope lifting device tension adjusting system has the advantages of small size, quick response, high adjusting accuracy and high stability.
