Many procedures in the development process of crane cabins today are still based on the specific expe-rience of manufacturers and historical guidelines. It is not surprising that they fail to meet the needs of a large proportion of operators. Accordingly, the need for more objective, theoretically justified and consis-tent models, that will minimiz...

Unlike previous studies that have revealed a link between quality improvement programs and organizational culture typologies in individual companies, this study describes organizational culture dimensions that affect the use of quality improvement tools and methodologies and how both affect supply chain company performance. Structural equation mode...

This study empirically examines the impact of quality tools on business performance in a sample of 119 Serbian industrial firms. Quality tools are classified into three primary groups according to their usage pattern by means of factor analysis and reliability testing: quality tools for reviewing current conditions, for analysing current conditions...

This paper develops a multi-criteria model for making decisions on the production programme relevant for industrial enterprises. It presents some possibilities of using the method of multi-criteria decision making with managerial decision making on the production programme and some possibilities of modelling and disclosing preferences of a decision...

Procedures in the development process of crane cabins are arbitrary and subjective. Since approximately 42% of incidents in the construction industry are linked to them, there is a need to collect fresh anthropometric data and provide additional recommendations for design. In this paper, dimensioning of the crane cabin interior space was carried ou...

In the conditions of modern market dynamics, corporate social responsibility (CSR) is increasingly evolving from a formal ethical principle into a powerful strategic instrument, key to achieving sustainable growth and long-term competitive advantage. Companies that integrate CSR into their business not only affirm the values of social responsibilit...

This semi-systematic review paper discusses four research questions based on findings from the last 10 years: What are the crucial issues in the ongoing debate on the development of the electric vehicle (EV) concept? Where are the major conflicting points and focuses between sustainable economy and EVs? How does the mining of metals and minerals fo...

Objectives. Considering that there is no standardized questionnaire for safety climate and resilience assessment, authors usually review a large number of questionnaires from the available literature, which results in a high number of questions distributed to respondents. As the questionnaire length increases, resistance from the respondents increa...

Although the mining industry plays a pivotal role in driving economic growth, it is also known for being one of the most dangerous work environments due to the high rates of injuries. Companies in the mining industry are faced with the challenge of applying occupational health and safety (OHS) measures in a manner to advance worker safety, health,...

Despite being very old, the mining industry continues to be one of the major sources of pollution, with more people killed or injured than in all other industries. Prevention of incidents/accidents on machinery in mining pits and the issues of operator safety on mining machinery largely depend on the ergonomic adaptation of the workplace, complianc...

Transport and mining machinery cabins are still not well adapted to their users, while checklists for their evaluation are not common in the literature.

An eight-year research and work on complex projects in the pharmaceutical industry is integrate...

The mining industry has been steadily expanding annually to keep up with the increasing demands. Consequently, used machinery needs to work efficiently, which indicates that unexpected downtimes should be at the minimum possible level. Proper identification and risk evaluation of the potential breakdown is the most important element for efficient e...

An appropriate maintenance strategy can maximize a machine's capacity and economic lifetime and also produce yearly savings of several million euros. That being said, a risk assessment approach can help companies identify the systemic bottlenecks that are interfering with their development and cut a large portion of their profit each year. This pap...

Numerous authors have demonstrated the effectiveness of the risk-based approach in the mining sector. However, the majority of earlier research has ignored the role that auxiliary machines, in total risk management play in favor of heavy machinery.

Mining equipment working time is critical for ensuring output and fulfilling mining project deadlines. In order to find trends and possible downtime minimization measures, this article analyses numerous types of excavators, dump trucks, loaders, backhoe loaders, bucket wheel excavators, and surface-top hammer drill rigs in Serbian mining sites. The...

Given the increasing challenges posed by climate change, reducing carbon – dioxide (CO2) emissions has become one of the key goals of the global community. Carbon – dioxide emissions are directly linked to the consumption of fossil fuels, which are used in various sectors, including transportation, industry, and energy. This research is based on co...

Increased mechanization in mining results in a larger number of workers being exposed to longer durations of whole-body vibration (WBV). Occupational exposure to vibration is associated with an increased risk of musculoskeletal pain in the back, neck, hands, shoulders, and hips; the development of peripheral and cardiovascular disorders and gastroi...

Maintenance is especially crucial when it comes to construction machinery due its capacity to avoid or reduce the risk of serious accidents by recognizing probable failures and downtimes in a timely manner. To properly implement maintenance strategy, it is required to identify the existing linkages between downtime and failures that have already oc...

Risk based approach has been proven in generating utility in the mining industry by multiple authors. However, most of the previous research has focused on heavy machinery, neglecting the impact that auxiliary machines have in overall risk management. The following study aims to propose a risk assessment methodology for auxiliary machinery in open-...

For the production planning process to be successful, an enterprise's internal business processes must be effective and efficient, while the DMAIC cycle is important aspect of practice-based continuous improvement. In accordance to those facts, this preliminary research includes the first part of the DMAIC methodology - “define“ and “measure“ tools...

Nowadays, fossil fuels are used in a clearly unsustainable way that can bring potentially catastrophic consequences.

Heavy mobile machinery cabs and their equipment are still not well adjusted to operators, so it is not surprising that we are still witnessing huge consequences of accidents at sites where they operate. The checklist with 39 questions, based on the previous research, is formed, and its’ measurement structure has been tested on the sample of 102 tra...

According to available literature, safety at work and productivity of cranes are a necessary and insufficiently researched topic. Both research directions are closely related because they depend on the number and type of stoppages that occur during operation of these construction machines. The focus of research should be on identifying the stoppage...

As industrial systems represent a complex socio-technical system, it is necessary to analyse the impact of manager-operator-machine interaction on industrial safety, as categories of contextual factors. However, modern scientific literature indicates insufficient research on this topic. This paper has an aim to empirically analyse behavioural style...

Although the biggest advancements could be expected from the mining industry as the oldest one, it is still a major source of air pollution, there are more people hurt or injured than in any other industry, while social conflicts around it are worldwide spread. The reason for the lack of expected progress in the area is the most likely the fact tha...

Nowadays, safety and sustainable business success cannot be viewed in isolation. Risk assessment is a prerequisite for adequate planning of prevention of destruction of critical potentials, as well as preparation of a strategy for response to failure in the context of prevention of consequences. An important part of all construction equipment maint...

The subject research is aimed at pointing out the methodology of identification, classification and risk analysis of mining machines.
