钳式吊啃道之所以特别严重,除了一些共性问题以外,还有其特殊的矛盾。1.自重系数大吊车的自重系数G/Q+G,或者比值Q/G,直接影响满载或空载的轮压变化范围。据大起、太重及《钢铁技术》1975年第4期的资料,各种桥式类型吊车的自重系数如表4所示。根据表4,100吨以下通用桥吊自重系数为0.44～0.65,载荷引起的轮压为自重引起的轮压的 The reason why clamp type gnawing Road is particularly serious, in addition to some common problems, there are also its special contradictions. 1. Self-weight coefficient of the crane’s self-weight coefficient G / Q + G, or the ratio of Q / G, a direct impact on full load or no load fluctuation range. According to the data of large, heavy and “Steel Technology” No. 4 of 1975, the self-weight coefficients of various types of bridge-type cranes are shown in Table 4. According to Table 4, the self-weight coefficient of universal bridge crane below 100 tons is 0.44 ~ 0.65, the wheel pressure caused by load is the wheel pressure caused by self-weight
