FOUR CABLE OPERATED SCISSORS GRAB
A four cable operated scissors grab (1), comprising a pair of scissor levers (2a, 2b) that are pivotably connected via a pivot joint (3), which scissor levers each include a grab shell (5a, 5b) and a hoist cable connection situated on a first side of the lever with respect to the pivot joint, and a closing cable connection (8a, 8b) situated on a second side of the lever that is opposite with respect to the pivot joint, so that in use a dedicated hoisting cable is fastened to each lever on the first side of the lever, and a dedicated closing cable is fastened to each lever at the second side of the lever, in which the scissor the levers are arranged to pivot about the pivot axis (4) between a closed position of the grab in which side and bottom edges of the shells are adjacent each other and the shells cooperate to form a bucket that can hold material to be handled, and a fully opened position of the grab in which the side and bottom edges are spaced apart and define a maximum opening there between through which material to be handled can pass, wherein when the grab moves from the closed position to the fully opened open position, a plane through the pivot axis and the side and bottom edges of each grab shell has an angular displacement about the pivot axis that is included in the range of 50 - 70 degrees.
