| 摘 要： | 通过模型试验，得知撑杆式抓斗及剪式抓斗闭合力矩的增长过程不同，一个是先强后弱，另一个是先弱后强．根据试验结果推断，得出双绳抓斗合宜的闭合力矩曲线，提出实现这种曲线的抓斗．

| Abstract: | A model grab experiment results show that the curve of grab moment of bucket of thrust rod grab and scissor grab reveals quite different shape. The former has a intense initial region and a weak ending, the latter has a weaker initial region and a very strong end. Authors suppose from the results of the test a rational grab moment curve and propose grabs fulfil that curve. |
