EXPERIMENTAL RESULTS ON THE EFFECTIVENESS OF AN IMPROVED EXCAVATOR BUCKET TOOTH DESIGN

Аннотация

From analysis of the performance of hydraulic excavators, it has been found that many hydraulic excavators used in mining operations operate at lower capacities than indicated in the technical description. This can be caused by unexpected work interruptions, rapid failure of parts, and unreliability of the excavator's working parts. In this article developments on improvement of cutting elements with increased service life for increase of productivity of open-pit excavators are resulted. Also, results of experimental tests of the improved teeth of an excavator bucket are submitted. KEYWORDS Quarry, excavator, bucket, tooth, protective element, efficiency, office hours, credibility, rock, abrasive wear.
