Publication number: 20160251863Abstract: A system and a method for automatically regulating the tensions of the guide ropes of a flexible cable suspension platform. The system includes a guide rope regulator mounted on a flexible cable suspension platform, a hydraulic pump station arranged on the flexible cable suspension platform, and a hydraulic system associated to the hydraulic pump station. The guide rope regulator automatically regulates the tensions of the guide ropes to enable the tensions of all the guide ropes to be consistent, so as to further ensure that the flexible cable suspension platform is in a level condition. The guide rope regulator also can measure the tension states of the guide ropes conveniently so as to ensure that the guide ropes have enough tensions to efficiently limit the swing amplitude of a lilting container. The system is simple and convenient to operate, and has a good automatic regulating effect.Type: ApplicationFiled: January 27, 2014Publication date: September 1, 2016Inventors: Guohua Cao, Yandong Wang, Zhencai Zhu, Weihong Peng, Jinjie Wang, Zhi Liu, Shangzeng Liu, Gang Shen, Jishan Xia, Lei Zhang
