Die bekannten Schienengreifern weisen folgende Nachteile auf:

  • eine den Anforderungen des Arbeitsschutzes entsprechende nachhaltige Sicherung des Schienengreifers gegen ungewolltes Öffnen ist nicht ausreichend vorhanden
  • die bekannten Sicherungen sind entweder anfällig gegen ein Verklemmen der Kipp- oder Klappmechanismen oder weisen aufwendige Hydraulikkolben-Konstruktionen mit entsprechenden Zu- und Ableitungen auf
  • die Konstruktionen der bekannten Greifer sind schwer, unhandlich und wuchtig
  • nebeneinander liegende Schienen können ohne Verschiebetätigkeit nicht aufgenommen werden (zu geringer Abstand der Schienenköpfe)
  • es besteht keine Möglichkeit der Verladung in Randbereichen der Ladeflächen bei LKW's und Waggons
  • die Entriegelung der bekannten Zangen ist aufwändig und gefährlich
  • die Entriegelungsgriffe sind sehr reparaturanfällig
The known rail grippers have the following disadvantages:
  • A sustainable protection of the rail grab against unintentional opening, which meets the requirements of occupational safety, is not sufficiently available
  • the known fuses are either prone to jamming the tilting or folding mechanisms or have elaborate hydraulic piston constructions with corresponding inlets and outlets
