FIELD: adapters.
SUBSTANCE: invention relates to adapters intended for equipping top-grip spreaders of gantry cranes and reachstackers of container terminals when performing loading and unloading operations with cargo. The lifting adapter for moving the means of fastening the semi-trailer contains longitudinal and transverse beams and suspensions forming a frame, fittings are placed on the transverse beams. On the longitudinal there are brackets for placing suspensions. The fittings are rigidly fixed on the plates installed on the upper flanges of the transverse beams, the brackets are located on the lower flanges of the longitudinal beams and are made with the possibility of attaching hangers to them, at both ends of each of which rigging brackets are placed. The hangers are made of chains and contain connecting links at the end of each chain, which, on the side where the hanger is attached to the frame, are connected to an omega-shaped rigging bracket; and longitudinal beams are connected by braces isolated from fittings.
EFFECT: increased strength, rigidity, structural reliability and increased service life.
