Abstract:

Heavy machinery allows for the efficient, precise, and safe management of large-scale operations that are beyond the abilities of humans. Heavy machinery breakdowns or failures lead to unexpected downtime, increasing maintenance costs, project delays, and leading to a negative impact on personnel safety. Predictive maintenance is a maintenance strategy that predicts possible breakdowns of equipment using data analysis, pattern recognition, and machine learning. In this paper, vibration-based condition monitoring studies are reviewed with a focus on the devices and methods used for data collect

Irrespective of the large impact exerted by the building sector on the environment because of intensive resource and energy utilization, much less attention has been paid to understanding the emission contributions due to machinery and resource consumption in pile foundation construction. Four piling sites were selected in Sri Lanka to estimate and compare the contribution on Global Warming Potential (GWP) caused by heavy machinery and material use for in-situ bored pile construction, based on the Intergovernmental Panel on Climate Change (IPCC) methodology.

Abstract Current estimates of the actual productivity of heavy construction machinery at a construction site are not supported by an appropriate and widely used methodology. Recently, for the purpose of estimating the actual productivity of heavy construction machinery, vision-based technologies are used. This paper emphasizes the importance of estimating actual productivity and presents a way (i.e. a research framework) to achieve it. Therefore, the aim of this paper is to propose a simple research framework (SRF) for quick and practical estimates of excavator actual productivity and cycle ti

Ever inreasing demand to raw mineral production stimulates intense use of mining machinery and subsequently exposes mining machinery operators to high levels of continuous noise. Long-term exposure to high levels of continuous noise can cause Occupational Hearing Loss (OHL) on operators. In order to certify a good working environment, it is important to estimate real noise levels of opencast mining machines. The aim of this study was to assess exposure levels to continuous noise using the test records of continouos noise emitted from mining machinery and recommend some actions to reduce it. Ar

Abstract:

The detection of local damage in rotating machinery (gears, bearings) via vibration signal analysis is one of the most powerful techniques in condition monitoring. However, in some cases, especially in heavy industrial machinery, it is difficult to detect damage because of the poor signal-to-noise ratio of the measured vibration. Therefore it is necessary to use unconventional advanced techniques to enhance the signal. In this paper, a novel approach based on parametric time-frequency analysis and further processing for: i) time-varying spectral content modelling, ii) the identification of inf

Abstract:

Raw vibration signals measured on the machine housing in industrial conditions are complex and can be modeled as an additive mixture of several processes (with different statistical properties) related to normal operation of machine, damage related to one (or more) of its part, some noise, etc. In the case of local damage in rotating machines, contribution of informative process related to damage is hidden in the raw signal so its detection is difficult. In this paper we propose to use the statistical modeling of vibration time series to identify these components. Building the model of raw sig

The manufacturing sector in Malaysia is categorized as one of the dangerous work sectors with a high accident record. The use of heavy machinery, unsafe working conditions, and hazardous materials handling is among the causes of many work-related accidents recorded among factory workers. In addition, the lack of safety training and low safety management commitment towards worker safety also contributed to the increasing number in this statistic. The goal of this investigation is to determine the link between management commitment and safety training on safety behaviour among workers. This stud

The pervasive use of welded components in critical industrial equipment, ranging from heavy machinery to high-pressure vessels, presents a significant vulnerability. Inadequate analysis and subsequent fatigue failures not only trigger costly production disruptions and severe workplace accidents but also pose a substantial impediment to achieving global net-zero targets, sustainable economic growth, and the broader objectives of the Sustainable Development Goals (SDGs). Understanding the fatigue behavior of welded materials, especially in the critical heat-affected zone (HAZ), is paramount for
