PALA DI SCAVO PER ESCAVATRICE

摘要

The shovel for an excavator has teeth arranged at a distance apart from one another on its digging edge. The areas of the edge of the shovel between the teeth are equipped with caps that are relatively resistant to wear and are put on in such a manner that they can be replaced, and have a short hook-like projection which engages under the edge of the shovel and a long leg which fits over the edge of the shovel. Secured to the upper surface of the shovel between the teeth of the shovel are retaining pieces which can fit together with the legs of the caps when the caps are put onto the edge of the shovel and which cooperate with them in an interengaging manner to prevent the legs of the caps from being lifted off from the upper surface of the shovel. Detachable securing members hold the legs of the caps and the retaining pieces together in the direction in which they can be fit together.
