A METHOD FOR FASTENING THE CLAW OF A LIFTING DEVICE TO A LIFTING ARM  AND A LIFTING DEVICE

摘要

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 When the lifting claw is withdrawn or exposed  it turns around the first and second rotation axes.
