ABSTRACT:
A method and apparatus for transporting loads includes a gripper pliers including a pair of pivotable gripper arms, each of which has a gripper claw. A positioning element is operatively coupled to the pair of gripper arms for pivoting the gripper arms in a pivoting plane and displacing the gripper arms in a gripping direction transversely of the pivoting plane into a position so that the gripper claws can engage connecting regions of the load. At least one of the gripper arms includes a transverse guide for fixing it against further pivoting and back-pivoting within the pivoting plane after the gripper arm has pivoted into an operating position for being displaced in the gripping direction.
