千(qian)斤(jin)頂(ding)(ding)大(da)(da)小選(xuan)用(yong)(yong)(yong)要與張(zhang)拉(la)錨(mao)具型(xing)號相匹配，具體選(xuan)擇簡便辦法：用(yong)(yong)(yong)錨(mao)具孔數乘以20噸(dun)得到即(ji)為最小匹配千(qian)斤(jin)頂(ding)(ding)噸(dun)位(wei)。例如：錨(mao)具15-5，即(ji)5x20t=100t，因此(ci)張(zhang)拉(la)時所選(xuan)用(yong)(yong)(yong)的最小千(qian)斤(jin)頂(ding)(ding)型(xing)號為100t，通常實際操作(zuo)選(xuan)用(yong)(yong)(yong)比最小型(xing)號大(da)(da)一型(xing)號的千(qian)斤(jin)頂(ding)(ding)為宜(yi)。
