Hook Tensioner

A hook clamp, comprising:

• a clamping hook configured to be received in an opening of a component which is to be clamped, the clamping hook having a first clamping hook arm with a hook element formed on a free end thereof, and a second clamping hook arm arranged at an angle relative to the first clamping hook arm;
• an actuator assembly configured to move the clamping hook from an open position into a closed position by movement in a first direction that is parallel to a longitudinal axis of the first clamping hook arm and also in a second direction that is perpendicular to the longitudinal axis of the first clamping hook arm, the actuator assembly including:
• an operating rod which is pivotably connected to the first clamping hook arm at the pivot point, and orientated in a direction parallel to the longitudinal axis of the first clamping hook arm;
• a lever mechanism configured to transmit a force to the operating rod in a manner which moves the clamping hook to the closed position;
• and
• an electric motor to drive the lever mechanism;
• and
• a spring element configured to pre-tension the clamping hook against the first direction at a pre-tensioning position between the pivot point and the hook element.
