ABSTRACT:
The invention relates to a device for clamping and unclamping of components with the aid of a clamping flange, at least one of said components being clamped by the hook of said device, the clamping force being transferred via a bolt linked with the hook and a nut that can be operated from the external side. The invention provides for a device clamped and unclamped by means of a tool such as an impact wrench, the head of which need not be tilted, lifted or lowered.
The aim of the invention is achieved by means of nut (5) that is arranged in a fixture and that can be turned but yet remains in a defined position, and by means of hook (10) that is linked with bolt (6) and guided with the aid of element (12) in groove (11) of fixture (5), the hook thus performing upward and downward motions and being swivelled by at least 45.degree. around its longitudinal axis for unclamping the flange.
