近20年来,卷扬系统的发展经历了从低级到高级再到人性化、数字化的过程,给施工现代化带来了很大方便。一些大型建设项目,出现了为其工程吊装专门研制的特殊起重机。卷扬系统的发展概况见表1。卷扬系统是轮胎式、履带式起重机的升降机构,通过绕卷钢丝绳将旋转运动变为直线运动,完成重物的上升、停止、下降等一系列起吊工作流程。
In the past 20 years, the development of the winch system has gone through the process from low level to high level to humanization and digitization, bringing great convenience to the construction modernization. Some large-scale construction projects have seen the emergence of special cranes specially developed for their works. Winding system development in Table 1. Winch system is the tire, crawler crane lifting mechanism, through the winding wire rope will be rotary motion into a straight line to complete the weight of the rise, stop, drop and a series of lifting work processes.
