Buckets with replaceable corners and teeth for bucket-wheel and bucket chain excavators

designs of new buckets for bucket-wheel excavator and bucket chain excavators
numerical analysis of buckets and their cutting elements in terms of ultimate, fatigue and buckling strength
analysis of the trajectories of cutting elements
numerical analysis of the distribution of excavation forces
selection of optimum excavation angles
results of the implementation of the new buckets: significant increase in the durability of buckets, decrease in energy consumption and cutting dynamics, decrease in the frequency of bucket replacements
