Abstract (en)
[origin: WO2010149847A1] In a method, a lifting claw is connected to the lifting arm of a lifting device to be turnable around a first rotation axis. The lifting device comprises at least one lifting arm (18a, 18b) with a turnable lifting claw (20) for supporting a piece to be lifted. The lifting claw is connected to the lifting arm by means of a first rotation axis (30) which is supported to the lifting arm to be movable in the longitudinal direction of the lifting arm. Furthermore, the lifting claw comprises a second rotation axis (34) which is supported to the lifting arm to be movable in the direction transverse to the lifting arm. When the lifting claw is withdrawn or exposed, it turns around the first and second rotation axes. At the same time with the rotation, the first rotation axis moves in the longitudinal direction of the lifting arm and the second rotation axis moves in a direction transverse to the lifting arm. At the end of the lifting arm, there is a recess (22), in which the lifting claw is placed. At the vertical side walls (24, 25) of the recess there are elongated axis slots (28, 29), in which the ends of the first rotation axis are fitted. The second rotation axis is connected to the lifting arm by means of rocker levers (36). Advantageously, the lifting device is a coil lifter with two lifting arms.
