AB  - Последице отказа свих висококапацитетних машина јесу врло велики финансијски губици и озбиљни ризици по сигурност и здравље. Када је реч о багерским јединицама, финансијски губици изазвани застојем производње због отказа основне машине у систему површинске експлоатације, односно складиштења и отпреме угља, најчешће знатно превазилазе финансијске губитке изазване директном материјалном штетом, зависно од њиховог капацитета и врсте материјала који се откопава (угаљ или јаловина) [1‐5]. О величини негативних економских ефеката изазваних отказима/хаваријама упечатљиво говори податак да у САД и Европској унији укупни трошак изазван отказима машина и система износи приближно 4% од БНП [6].
Примена техничког решења омогућава решавање следећих проблема:
•	подизање нивоа одржавања, ефективности, поузданости и сигурности роторних багера, односно БТО/Д/У система;
•	подизање нивоа економичности експлоатације БТО/Д/У система; чиме се вишетрукуко смањују ризици током експлоатације и одржавања багерских јединица.
Осим тога, применом техничког решења стварају се основе за:
•	управљање поузданошћу и сигурношћу БТО/Д/У система;
•	испуњавање критеријума ригорозне регулативе везане за заштиту животне средине и сигурност руковалаца и одржавалаца.
На значај примене техничког решења у термоенергетици Србије упућују следећечињенице:
•	највећи произвођачи елекричне енергије у Србији су термоелектране. Према [7], 2014. године 65,1% електричне енергије у Србији произведено је из лигнита, док је у 2015. години 70,3 % електричне енергије добијено из поменутог извора;
•	РБ „Колубара“ даје ≈75% производње лигнита у Србији [7];
•	у цени електричне енергије угаљ учествује са ≈60%;
•	одржавање механизације на површинским коповима учествује са 35‐40% у цени угља;
•	у односу на пројектовани номинални век (35‐40 година), просечне старости машина (31,6 год. багера за континуални ископ, 31,1 год. одлагача и самоходних транспортера) и њихових капацитета (28,3 год. багера за континуални ископ, 27,2 год. одлагача и самоходних транспортера) у РБ „Колубара“, врло су високе;
•	сат застоја БТО/Д/У у РБ „Колубара“ нормира се као индиректна материјална штета у износу од 5000‐15000 €, зависно од капацитета машине, односно материјала који се откопава/транспортује.

AB  - 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 SMS risk assessment are very scarce in relevant literature. For this reason, this paper aims to establish a consistent risk quantification approach for bucket wheel excavators (BWEs), the backbones of these systems. Based on the original structural scheme of a BWE, the risk parameters assessing criteria stemming from multidecadal experience and the database of recorded standstills (in the considered case, one hour of SMS downtime generates indirect financial losses of approximate to 15000(sic)), a study was conducted applying the Service FMECA technique to the BWE SRs2000 (one of the best-selling models from "Takraf"), with the following conclusions: (a) the material conveying subsystem is the highest contributor in the total number of mechanical and electrical failures, as well as in total downtime; (b) during the monitoring period, there were no extreme risk level failures. Besides, corrective actions for reducing risk levels of the most critical mechanical and electrical failure modes are given in the paper. The presented approach for risk quantification for a BWE can be successfully applied to other SMS subsystems, notably spreaders.

AB  - The paper deals with numerical study on the stresses at the bolted end-plate moment connection, with application of finite element analysis. The prying effects in the joint are considered for the comparative analysis with analytical model of bolt calculation. There are observed three basic models of the joint which reflect variation of the joint stiffness, along with the cases of different parameters of end-plate thickness. It is shown that several parameters have effects on the stresses at the joint and need to be considered in the structural analysis of the frame structures. Also, there are given some recommendations for practical usage for the design of this kind of joints.

AB  - Bucket wheel excavators (BWEs) are a backbone of any power industry that heavily relies on surface exploitation. As such, any failure, breakdown or collapse of the machine or its subsystems poses a serious drawback in the efficiency of an entire mining system, and is strongly reflected on costs in labour, finances, material and downtime, and is also a potential risk to the safety of workers. This, combined with lengthy lifetime of the machines operating in open cast mines of Serbia (measured in decades), places immense value on the avoidance of potentially hazardous problems during all stages of their lifespan, namely the design, manufacture and exploitation phases. Over the past decades, demand for the ever-increasing capacity and efficiency of BWEs has led to failures which may indicate a need for the reassessment of the calculation methods and guides. This paper presents few such cases, along with the discussion about causes, and suggests an approach to dynamic behaviour analysis based on reduced spatial dynamic models of BWEs which enable modal analysis and the analysis of a dynamic response for continuous variation of constructional parameters.

AB  - Determining a bucket wheel excavator (BWE)'s slewing superstructure weight and its center of gravity (COG) is of extreme importance not only in the design phase, but also after the completion of the erection process and during the operation of the machine. This paper presents a critical comparative analysis of the basic parameters of the static stability of a BWE 1600 superstructure, with the parameters being obtained by both analytical and experimental procedures. The analysis shows that a relatively small difference in superstructure mass, obtained by calculation, leads to a relatively large unfavorable shifting of its COG, necessitating a significant increase in counterweight mass for balancing. A procedure for superstructure 3D model mass correction is presented based on results obtained by weighing after the completion of the erection process. The developed model provides enough accuracy to determine the superstructure's COG in the entire domain of the bucket wheel boom inclination angle, and enables accurate load analysis of the superstructure's vital parts. The importance of this analysis is reinforced by the finding that the procedure prescribed by standard DIN 22261-2 gives results which are not on the side of safety, as shown by an example of strength analysis of a bucket wheel boom stays' end eyes.

AB  - 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 accident state to the state of full exploitation readiness. After the accident, temporary stabilization of the superstructure was carried out as well as cutting off of severely damaged parts of the bucket wheel boom (BWB) with excavating device. Successful completion of the very delicate BWE rescue and balancing operation was followed by the reconstruction of the heavily damaged slewing platform. The integrity of the slewing platform structure was preserved by removing structural parts which were seriously damaged during long-term exploitation and breakdown, and installing the newly designed elements in critical zones. The redesign of the slewing platform structure produced favorable loads and stiffness distribution while eliminating geometrical stress concentrators. Comparative analyses of the stress states pointed out that the redesigned slewing platform structure meets the strength criterion, unlike the original structure. The redesign solution enabled reconstruction in field conditions. This way the time of the reconstruction realization was drastically cut and losses due to the downtime of the machine were reduced several times over. After completing the slewing platform reconstruction, the newly manufactured BWB structural elements as well as the newly manufactured bucket wheel with drive were installed i.e. a partial revitalization of the BWE was done and by that the BWE's life was essentially prolonged.

AB  - 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 in this paper was to diagnose the cause of the damage of the bucket wheel excavator crawler chain links. In order to identify the reasons behind chain link failures, stress state calculations were performed as well as experimental investigations which, given the nature of the failure, included visual and metallographic examinations, chemical composition analysis and tests of mechanical properties. Based on the results of the numerical-experimental analyses, it was concluded that the chain link breakdowns are caused by 'manufacturing-in' defects. The results of the presented analyses also emphasize the importance of a comprehensive quality control of chain links.

AB  - Prior to conducting complete life cycle assessment of the bucket wheel
excavator's belt conveyor, simplified life cycle assessment of its components has to be
done. One of these components is return belt idler support 0°, which consists of idler
support and three rollers. Simplified life cycle assessment of the idler roller is
conducted with Ecodesign Assistant and Ecodesign PILOT tools. Conducted analysis
has shown that the most significant stage of the idler roller life cycle is raw materials
stage. Suggested strategies provide possible improvements towards more
environmentally friendly and energy efficient idler roller design.

AB  - The slewing platform is the fundamental part of the bucket wheel excavator (BWE) structure. The occurrence and propagation of cracks in the zones of the slewing platform mantle holes, may probably lead to BWE collapse. The goals of the study presented in the paper were to: (1) Diagnose the cause of cracks occurrence; (2) Define the reconstruction design of the mantle; (3) Verify the reconstructed structure by numerical-experimental analysis. The identification of the stress-strain state of the mantle is done by applying the finite element method. Experimental stress analysis of the reconstructed mantle's structure is executed two times in the BWE real working conditions, using methods of strain gauges. The maximum measured value of stress is about 10% lower in relation to the calculated value of stress for the studied load case. Speaking from the engineering standpoint, the mentioned deviation is quite acceptable, particularly having in mind the stochastic character of the excavation process. Besides experimental investigations, the validity of the presented reconstruction also unquestionably confirms the mentioned failure-free exploitation, while the BWE excavated more than 2.6 x 10(6) t of coal after the reconstruction.

AB  - This paper discusses the cause of the failure in the vital part of the crawler travel gear of the bucket wheel excavator (BWE) - two-wheel bogie (TWB). The results of the finite element analysis (FEA) point out that the main reason of the TWB failure is its insufficient strength under lateral forces acting during curve travel. The weak points in the TWB structure are removed by suitable redesign while keeping in mind all restrictions ensuing from installation conditions and functionality of the existing crawler travel gear. In addition to the numerical analysis (FEA), a parallel experimental analysis of the original as well as the redesigned TWB is conducted on a test board especially designed for this purpose. The experimental results have confirmed the considerably improved response on lateral loads of the redesigned TWB. The exploitation of the redesigned TWB with no failures has confirmed the validity of the reconstruction design.
