FIELD: mechanical engineering; load-gripping devices.

SUBSTANCE: invention relates to device used for demounting (releasing) of sling from load. Proposed device has base 16 with part 27 for catching by crane made for engaging hook of crane by upper part. Each of first shafts 11 attached to base at level which is lower than part designed for catching by crane is provided with level holder 17 hinge connected in its middle part. Each of second shafts 12 attached to base at level which is lower than that of first shafts has first end of connecting lever 18 connected for turning and arranged at base. Second end of connecting lever is interlocked with first end of lever holder with possibility of disengagement. One end of sling 13 is attached to crane hook and it can catch heavy article, and other end is secured around connecting lever for disconnection. Moreover, release device 19 disconnects corresponding end of connecting lever from corresponding end of lever holder.
