A problem to be solved by the present invention is to provide a safety lifting system for a gang form. According to the present invention, since a safety cover covers a fastening bolt, dismantlement is impossible when a lifting loop is not held by the hook of a crane. Only when the lifting loop is held by the hook of the crane, the safety cover moves and enables the dismantlement of the fastening bolt, thereby completely preventing accidents caused by dismantlement of all fastening bolts while the lifting loop is not held by the hook of the crane. The solution of the present invention is obtained by a safety gang form lifting system which comprises: a lifting loop member in which the lifting loop protrudes from a vertical member of the gang form, upper and lower guide members which are installed in both lateral sides of the vertical member, a safety loop member which is inserted in the guide member and installed therein to position the safety loop unit adjacent to the lifting loop, the safety cover which is horizontally installed in the corresponding position to the fastening bolt and intersects with the vertical member, and a spring member which is installed between the safety cover and guide member. |
