Blast-Free Technology of Mineral Mining: State and Prospects. Part I: Experience of Study and Development of Excavators with the Dynamic Bucket

The design features of a mining excavator with the dynamic bucket and the results of investigations into the loads in mechanisms and metal constructions of the machine are described. The possibility is substantiated for the creation of quarry excavators - power shovels with the dynamic bucket as modifications of mass-produced machines with minimum new units.
