目前,建筑工地上,由于塔式起重机弯道作业困难,普遍存在多立塔式起重机的现象。采用塔式起重机直角弯道的快速施工——快速倒链弯轨法,有利于改善这种状况,为国内外塔吊行业提供了一种弯轨成型的新技术,可较大幅度地提高塔吊效能,降低机械化施工成本。1988年3月,“快速倒链弯轨法”被评为北京市科技进步三等奖。1989年10月,在亚运会工程“首体速滑馆”环状塔道上安立两台
At present, on the construction site, due to the difficult operation of tower cranes, there is a common phenomenon of multiple tower cranes. The rapid construction of the right angle bend of the tower crane, the fast chain-turning and bending track method, is beneficial to the improvement of this situation. It provides a new technology for forming the curved rail for the crane industry at home and abroad, and can greatly improve the tower crane performance. , Reduce mechanized construction costs. In March 1988, the “rapid chain-turning track method” was awarded the third prize of Beijing Science and Technology Progress Award. In October 1989, two of the two were erected on the Asian Games Project“the first speed skating museum” ring tower.
