TLDR
A replaceable cutting edge for an excavating bucket comprises a number of tip adapters which are mounted in laterally spaced apart, fixed positions on the leading edge of the bucket.Abstract:
A replaceable cutting edge for an excavating bucket comprises a number of tip adapters which are mounted in laterally spaced apart, fixed positions on the leading edge of the bucket. Each of the tip adapters has at least one pair of vertically spaced apart flanges facing an adjacent tip adapter. A cutting edge section extends between each pair of adjacent tip adapters with the ends of the cutting edge section held in vertical position by the flanges on the tip adapters. A retaining pin, in the form of a wedge member, extends through aligned openings in the flanges and in the ends of the cutting edge sections to hold the cutting edge sections in horizontal position on the bucket leading edge. Each retaining pin has a tapered surface which mates with a corresponding tapered surface in the opening of the cutting edge section to force the cutting edge section to the rear and tight against the leading edge of the bucket.read more
