1964年冬,在江西某站需要架設高出地面12.8米的过河索。当时附近买不到預制鋼筋混凝土杆,而自浇这样高的鋼筋混凝土杆,或用自立式拉线球鉸式的鋼支架也有困难,因而在設計工作革命化的思想指导下,試制了一种拉线土鉸式鋼支架,支架净高12米, The winter of 1964, Jiangxi station need to set up 12.8 meters above the ground across the river cable. At that time, it was difficult to buy prefabricated reinforced concrete poles nearby, and self-pouring such high-strength reinforced concrete poles or steel brackets using self-supporting pull wire ball hinged steel supports. Under the guidance of revolutionizing design work, Soil hinge steel brackets, brackets net height of 12 meters,
