The invention provides a rope system for changing amplitude, which comprises a steel wire rope, two amplitude-variable winches, two amplitude-variable pulley blocks and a steel wire rope connecting device, the steel wire rope connecting device is arranged between the two amplitude-variable pulley blocks, the amplitude-variable winches are arranged on a revolving platform, and the steel wire rope connecting device is arranged on the revolving platform. The variable-amplitude pulley block comprises a first variable-amplitude pulley yoke and a second variable-amplitude pulley yoke, the first variable-amplitude pulley yoke is arranged at the head of the suspension arm, the second variable-amplitude pulley yoke is arranged on the tripod, one end of the steel wire rope is connected to the variable-amplitude winch, and the other end of the steel wire rope bypasses the variable-amplitude pulley yoke to be fixedly connected with the steel wire rope connecting device; the range of the changeable amplitude is large, and the influence on the cargo boom structure can be reduced.

    本发明提供一种改变幅度用绳索系统,包括钢丝绳、两个变幅绞车、两个变幅滑轮组以及钢丝绳连接装置,所述钢丝绳连接装置设置在所述两个变幅滑轮组之间,所述变幅绞车设置在回转平台上,所述变幅滑轮组包括第一变幅滑轮架和第二变幅滑轮架,所述第一变幅滑轮架设置在吊臂头部,所述第二变幅滑轮架设置在三脚架上,所述钢丝绳的一端连接在变幅绞车上,钢丝绳的另一端绕过变幅滑轮架与钢丝绳连接装置固定连接,本发明能够改变幅度的范围大,且能够减少对起重臂结构的影响。
