The invention relates to the field of crane hoisting, in particular to an adjustable lifting hook group. The top frame and the adjusting table are connected in series through a lifting rope, the lifting hook assembly is detachably connected with the lifting rope, and the top frame and the adjusting table form an adjustable two-section type structure. The top frame is connected with a hoisting end of a crane; a winding piece for controlling the length of the lifting rope is arranged on the top frame; the adjusting table is connected below the top frame and comprises an adjusting cylinder connected with the top frame; the chassis is positioned at the bottom of the adjusting cylinder; a plurality of groups of adjusting pieces are arranged along the periphery of the chassis for the lifting ropes to penetrate through in one-to-one correspondence; the lifting hook assemblies are detachably connected to the bottoms of the lifting ropes in a one-to-one correspondence mode. The two groups of hoisting pieces I rotate reversely; the second hoisting pieces synchronously ascend and descend between the two first hoisting pieces. According to the invention, through the combination of the lifting hooks in various forms, the lifting mode, position and height are adjusted, so that the lifting requirements of transportation pieces in different forms are met, and the lifting convenience, flexibility and practicability of the crane are improved.
