(Pergamon-Elsevier Science Ltd, Oxford, 2009)
This paper discusses the results of the investigation of occurrence of cracks in the structure of bucket wheel excavator (BWE) slewing platform, the repair procedure and the reconstruction of the slewing platform. The ...
Failure analysis of the end eye connection of the bucket wheel excavator portal tie-rod support
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
This paper describes the failure analysis results of the bucket wheel excavator (BWE) portal tie-rod support. The results of finite elements analysis (FEA) point out the occurrence of pronounced stress concentration, whereby ...
Load-bearing steel structure diagnostics on bucket wheel excavator, for the purpose of failure prevention
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The appearance of cracks on load-bearing steel structure of compact, hydraulic bucket wheel excavator was a perennial problem. Unfavourable stress concentration, inadequate geometry and structure of materials, inadequate ...
Failure investigation of the bucket wheel excavator crawler chain link
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The high mobility of open pit machines in heavy duty conditions provides fertile ground for the occurrence of various failures of the traveling mechanisms' vital parts such as chain links. The goal of the study presented ...
Disaster of the bucket wheel excavator caused by extreme environmental impact: Consequences, rescue and reconstruction
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
A slope failure was the cause of a severe accident of bucket wheel excavator (BWE) Takraf SRs 1200. This paper is dedicated to the engineering challenges that accompanied the process of returning the BWE from its after ...
'Designing-in' failures and redesign of bucket wheel excavator undercarriage
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The traveling mechanism of the C-700S bucket wheel excavator is of the two-crawler type. Rigid connections between the undercarriage and the crawler beams offer a very high factor of safety against tipping but at the same ...
Failure of the bucket wheel excavator buckets
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Buckets are a vital substructure of all digging machines, and are intended for the realisation of the fundamental machine function - soil excavation. This paper presents the results of the experimental-numerical investigation ...
Service FMECA of a bucket wheel excavator
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Surface mining systems (SMSs) are among the most significant 20th century achievements in mining industry, whose significance to miners is comparable to the invention of dynamite in the 19th century. However, problems of ...
Human factor risk management procedures applied in the case of open pit mine
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
Risk management aims to provide a controlled work environment to ensure the safe operation of the high-risk systems. It is a dynamic process which work in a continual state of change. The issue of human factor risk and ...
