Z obrazkov a udajov na uvedenych web strankach sa da usudit ze sa nejedna o momentovy kluc lucovy, ale ramenny alebo s ramenom. To bude na vas ako to prelozite. Beam neznamena len luc, ale aj hrada, nosnik, tram a pod. Najskor som si myslela ze to ma nieco spolocne s nosnikmy. Beam ovsem znamena aj rameno vahy ....Na web stranke www.toolking.com (type beam torque wrench )
www.cscforce.com, www.smokesign.com su obrazky ale len jeden druh momentovych klucov na rameno, s nazvom, beam torque wrench.
Opis ako tento kluc funguje: Operation:Load is applied against handle and deflects ( vychyli ) the beam ( rameno ) with attached torque scale; pointer or indicator remains stationary".
