  • Patent number: 5735728
    Abstract: A device for lifting and moving beehive boxes has two legs hinged at their upper ends to form a triangular structure having a suspension joint at its apex. A chain is hooked to the apex of the triangular structure, and a gripper is suspended to the chain. Lower ends of the two legs are connected by a rope which prevents them from moving apart and facilitates in adjusting the distance between them. To move an upper box of the beehive, the two legs are spread apart and pressed against the ground, the structure is tilted toward the beehive so that the gripper engages the hand recesses on two opposite side walls of the upper box, and then the structure is tilted away from the beehive, such that the box is initially slightly lifted above the lower box of the beehive and then is moved towards the desired position away from the beehive.
