【Abstract】 This paper points out the problems existing the con trolling system of electric pulling formerly in dual interlock. In the course of teaching, the original way has its disadvantages, such as, the complicated proc ess, the unreasonable structure, the inaccurate length of wire, etc. It is prove d that this new control circuit is excellent in function, convenient in utilizat ion, and easier for students to grasp. Especially, good teaching effect is achie ved.更多还原
