The present invention relates to a tong key apparatus for a tongs crane. The tong key apparatus for the tongs crane of the present invention has an improved structure in which a contact portion between a head of a tong key and a locking case is formed into first and second inclined surfaces corresponding to each other, so that when the crane is lifted, a force moment with respect to the contact portion between the head and the locking case is stably distributed, thereby reducing a risk of damage, and the center of the locking case and the center of the head can be easily matched, so that movement of the crane during lifting operation can be suppressed and the strength of the contact portion can be enhanced. The tong key apparatus for the tongs crane comprises left and right grippers (42, 44), and a tong key assembly (100).

    본 발명은 통키의 헤드 부위와 록킹 케이스의 접촉 부위를 각각 대응되는 제1,2경사면으로 형성시켜 크레인의 상승동작시 헤드 부위와 록킹 케이스의 접촉부위에 대한 힘모멘트를 안정적으로 분산시켜 파손 위험을 줄일 수 있도록 함과 아울러, 록킹 케이스와 헤드의 중심을 용이하게 일치시킬 수 있게 되어 크레인의 승강동작시 유동을 억제시킬 수 있으며, 접촉 부위에 대한 강도를 향상시킬 수 있도록 그 구조가 개선된 통스크레인용 통키장치에 관한 것이다.
