Abstract

PROBLEM TO BE SOLVED: To uniformize the use frequency of control contactors and prevent abnormal abrasion and inferior contact of the control contactors by reversing the action of a plurality of contactors having reverse role in control. SOLUTION: When upward driving is performed in general, an upward driving key switch 4 is closed, a circuit of a power source P, a normally open contact 4a1, an upward driving command 1, and a power source N is closed, the upward driving command 1 is energized, and a motor rotates upward. Where a control contactor changeover switch 3 is closed, a normally open contact Aa2 is closed by an energization of the control contactor changeover relay A and where the upward driving key switch 4 is closed, a circuit of the power source P, the normally open contact 4a1, the normally open contact Aa2, a downward driving command 2, and the power supply N is closed, and the downward driving command 2 is energized. The motor rotates upward. When a constant- direction driving is performed by the operation of a control contactor changeover switch 3, the upward driving command 1 and the downward driving command 2 are selectively used.
