GRIPPING DEVICE Russian patent published in 2017 - IPC B63C7/00 

FIELD: transportation.

SUBSTANCE: gripping device includes the bearing element adapted to be hung on the ship lifting devices, with symmetrical grips and their hydraulic drives, the receptacle to accommodate the equipment operating from external energy sources. The bearing element is made in the form of at least one volume U-shaped housing, in the upper horizontal portion of which strong buoyancy tanks and an equipment tank are mounted symmetrically. At least two symmetrical grips are rigidly fixed on the rotary axes mounted on the lower ends of the vertical parts of the U-shaped housing, and are pivotally connected by their outer surfaces by means of hinged-lever links to the drive hydrocylinders mounted on the lateral outer surfaces of the U-shaped housing. Said housing and grips are in the form of volume rib structures of U-shaped frames and flat arched rib elements with cutouts and rigid lintels, rigidly fixed at intervals of 400-600 mm respectively. The U-shaped housing is made with the possibility of the hinge joint of the rigid bond to its two surfaces.

EFFECT: design simplification, increasing the lifting capacity and improving the reliability of the device.
