国内塔机的回转机构一般来说可靠性较差 ,容易发生故障 ,主要表现在塔机吊重慢就位困难 ,影响施工速度和安全 ,而且使塔机经常承受回转冲击扭矩 ,易造成钢结构疲劳 ,连接件松动 ,产生事故隐患 ,影响塔机使用寿命。针对此类问题 ,我们进行深入研究 ,并经多次试验 ,设计制造了一?
Domestic tower crane rotary mechanism generally less reliable, prone to failure, mainly in the tower crane slow place in place, affecting the construction speed and safety, but also to bear the tower crane rotary impact torque, easy to cause steel structure Fatigue, loose connectors, resulting in hidden dangers of accidents, affecting tower crane life. In response to such problems, we conducted in-depth study, and after many trials, design and manufacture of a?
