Crane hoisting connection device

The utility model discloses a hoisting connecting device of a crane, which belongs to the technical field of constructional engineering machinery and comprises a hoisting frame, one side of the hoisting frame is fixedly connected with a connecting chain, and one end of the connecting chain is provided with a lifting hook. When the crane starts to work and the lifting hook is controlled by the connecting chain to start to work, the connecting chain shakes to drive the lifting hook to shake so as to influence the working efficiency, when the connecting chain shakes, the connecting chain collides with the buffer device to slow down shaking, and a baffle drives a connecting rod through a rotating shaft a and a rotating shaft b to push a fixing block to move towards the two sides; when a fixing block moves, a damping spring a is compressed, and a damping spring b is stretched to slow down shaking of a connecting chain, during long-time work, the connecting chain makes contact with a baffle too many times, damage c
