The invention discloses a multifunctional lifting device for an unmanned crane. The multifunctional lifting device comprises a base and a rotary disc; the position, close to the center position, of the top surface of the base is provided with the rotary disc, and the top of the rotary disc is fixedly provided with a supporting frame; the top of the supporting frame is provided with a supporting arm; when the height of an object does not reach the moving condition, a second hydraulic rod in a second hydraulic cylinder is controlled to move towards the outer side, thus, the clamping height of the object is further increased, the object moving height is reached, the object is avoided making contact with an object on the ground, and movable transferring work of the object in different directions is facilitated; the top of an installation seat is provided with a clamping plate, the clamping plate is provided with a through hole, and an insert rod penetrates through the interior of the through hole; the appearance outline of the clamping plate and the interior outline of a clamping groove are the same, so that when the clamping plate at the top of the installation seat is inserted into the clamping groove, the insert rod is inserted into the through hole formed in the clamping plate conveniently, installing work of the installation seat is facilitated, and a special gripper is convenient to replace; and the working efficiency is improved, and the time for maintaining and replacing a traditional gripper is greatly shortened.
