Dynamische Beanspruchungen: Wechselnd, Stroßbelastung, Vibrationen, Temperatur Dynamiske belastninger: Vekslende eller sjokkbelastninger, vibrasjon, temperatur
Normen empfehlen oder schreiben Sicherungsmaßnahmen vor Standarder anbefaler eller foreskriver låseelementer
Vorspannung allein ist kein Garant für ausreichende Sicherung Forspenning alene er ingen garanti for tilstrekkelig låsefunksjon
Andere Sicherungsmethoden sind wirkungslos (z.B. Kontern, Körnen, Palmutter, etc.) Andre sikringsmetoder er ineffektive (f.eks. dobbeltmutter, gjengestansing, palmutter osv.).
Erhält die Vorspannung (Konstruktionsprinzip einer Schraube) Opprettholder forspenningen (konstruksjonsprinsipp for en bolt)
Verhindert das Auseinanderfallen der Komponenten Forhindrer at boltekomponentene faller fra hverandre.
Konformes Sicherungselement (ETA, abZ, EBA) Samsvarende sikringselement (ETA, abZ, EBA)
Reduktion von Instandhaltungsmaßnahmen /-kosten Reduserer vedlikeholdsaktiviteter og kostnader
