Abstract

Ένα συγκρότημα φθοράς για εξοπλισμό εκσκαφής περιλαμβάνει μία βάση στερεωμένη στον εξοπλισμό εκσκαφής, ένα στοιχείο φθοράς συναρμοζόμενο επί της βάσης, και ένα τεμάχιο μανδάλωσης για να συγκρατεί με δυνατότητα απελευθέρωσης το στοιχείο φθοράς στη βάση. Το στοιχείο φθοράς περιλαμβάνει πλευρική ανακούφιση για τη μείωση της οπισθέλκουσας επί του συστήματος. Το στοιχείο φθοράς και η βάση περιλαμβάνουν έκαστο ένα ημισφαιρικό πρόσθιο άκρο και ένα γενικά τραπεζοειδές οπίσθιο τμήμα. Η βάση περιλαμβάνει ένα ρύγχος και ένα στοπ που προεξέχει από το ρύγχος για να συνεργάζεται με το τεμάχιο μανδάλωσης χωρίς να απαιτείται άνοιγμα για την υποδοχή του τεμαχίου μανδάλωσης εντός του ρύγχους. Το τεμάχιο μανδάλωσης είναι ένα επίμηκες τεμάχιο μανδάλωσης τοποθετημένο γενικά υπό αξονική διεύθυνση και το οποίο συγκρατεί το στοιχείο φθοράς στη βάση υπό φορτία θλίψης.
