ABSTRACT:
Apparatus for damping the swing of a loading device, said apparatus comprising a trolley provided with a hoisting machine having a hoisting rope on which a loading device is suspended, and downward-pointing brackets attached to the bottom of the trolley. A retaining lever provided with a joint, is mounted on each bracket enabling the lever to turn relative to the bracket. The loading device is so constructed that, when lifted up between the brackets, it will turn the retaining levers into a substantially vertical position. An anti-friction means is provided between the retaining lever and the loading device.
