ABSTRACT:
An earthmoving bucket for use with various types of wheel and track-type earthworking and construction machines is constructed to provide great strength and rigidity while at the same time not being unduly bulky or heavy. The bucket is further characterized by simplified manufacturability and cost advantages. Previous earthmoving buckets, which required considerable strength and durability, were quite heavy and bulky, with respect to bucket size, and required complicated, costly, and time-consuming assembly procedures. The earthmoving bucket of the present invention utilizes a pair of unitary cast lift hinge brackets which incorporates the pin bores for the lift linkage, the rack-back stops, and the bucket dump stops.
