The invention discloses a cradle which comprises a top frame and a plurality of sub-lifting frames positioned below the top frame, wherein the outer end of the upper end of each sub-lifting frame is hinged with the top frame; and each sub-lifting frame can rotate outwards to the first working position for opening the cradle along the hinge joint between the sub-lifting frame and top frame; the upper end of each sub-lifting frame is provided with a lifting rope, and the lifting rope can pull the corresponding sub-lifting frame to rotate inwards to the second working position for closing the cradle along the hinge joint between the sub-lifting frame and top frame; and when each sub-lifting frame is in the second working position, all the sub-lifting frames can form a containing cavity capable of containing the material to be lifted. According to the cradle disclosed by the invention, under the actions of the tensile force of the lifting ropes and the self gravity of the sub-lifting frames, all the sub-lifting frames can be opened or closed automatically, so that the whole material loading, lifting and unloading process basically does not need human powder, and thus, the hand labor intensity is low, thereby greatly enhancing the work efficiency.
