Abstract
Quick fastener system for fixing a tool at the end of a loading arm. The system includes a first part coupled to the loading arm. The first part includes a cradle and a first aperture. A second part is arranged on the tool. The second part includes an element having a hook-shaped extension and a shaft which is adapted to be engaged by the cradle. A locking member is adapted to engage the hook-shaped extension. The tool is movable by the loading arm when the cradle engages the shaft and when the locking member engages the hook-shaped extension.
