| Abstract: | The leader of the walking pile frame was analyzed in a simplified mechanical model when it was appended on a long screwing driller. According to the equation of the stability analysis, we studied the stability of the leader, and the effects of different supporting positions on the stability were discussed. The stability checking method and calculated examples of specific problems were also presented. |
