Abstract
A safety locking device for a lifting hook comprising a lifting part and a hook part having a first and a second shank arranged in the same plane, the first shank being attached to the lifting part. The safety-locking device is pivotably attached to either of the shanks or the lifting part and comprises a spring means formed integrally with the safety locking device, one end of which is attached to the safety locking device diametrically opposed its fastening point to either shank or the lifting part and the other end is arranged to bear on the opposite shank or the lifting part, to which the safety locking device is pivotably attached to automatically bring the safety locking device to bear on the lifting part or the opposite shank so as to prevent unhooking of a hoisting cable or similar means introduced into the hook part.
