Analysis of the costs of regeneration of excavator buckets used for brown coal excavation
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 1
Abstract
The paper presents the most frequently applied multibucket excavator solutions used in brown coal surface mining. The authors have analyzed the design of the excavator bucket individual components in terms of its wear during operation and the possibility of regeneration. The main aim of the performed analyses was to determine the costs of regeneration of the excavator buckets for selected multibucket excavators. Four selected excavators have been subject to the cost analysis. The cost of regeneration was estimated based on the prices of individual components such as bucket teeth, knives, forging, face as well as labor time needed to carry out full bucket regeneration. Based on the performed calculations and the experience of the mining personnel, it has been observed that in terms of economy, regeneration of an excavator bucket is more cost effective than purchasing a new one. However, severe mine working conditions as well as random damage sometimes force a purchase of new buckets for the excavators.
