FIELD: mechanical engineering.
SUBSTANCE: invention relates to load-gripping devices operating with load-lifting cranes. Proposed device contains frame with support platform for mounting and fastening on load and equipped with rigging units for connection to crane crossmember. Device is furnished with two guide rods for preliminarily directing the frame at its mounting on load, guides rods being turned into threaded holes in load. Support platforms arranged symmetrically n frame are equipped with nondetachable spring-loaded bolts for fastening frame on load, moved off by springs after turning out. One of platforms is furnished with round pin taking up loads in all directions when mounting rigging device on load and fitted in mating hole of load. Other platform is provided in pin having two parallel planes and made for turning around longitudinal axle to provided complete fitting to mating parallel planes of corresponding hole in load. Each support platform, free from pins, is provided with hole for corresponding stop mounted on load for contact with screw after fastening of support platform by said bolts, and with hole for arrangement of corresponding said rod.
EFFECT: improved safety at lifting and tipping.
