“…However, carrying loads on the head produce contradictory results. Some authors report that is one of the most economical ways to transport heavy loads (Charteris et al, 1989; Kumar et al, 2021; Maloiy et al, 1986), and two studies carrying weights on the head detect the Free‐Ride (Charteris et al, 1989; Jones et al, 1987) (Table 1 and Figure 3). Nevertheless, other authors comparing head‐load positions with other methods disagree with this assumption (Lloyd, Parr, Davies, & Cooke, 2010; Lloyd, Parr, Davies, Partridge, & Cooke, 2010).…”

Objectives: Several researchers have obtained discordant results testing the human capability to transport loads without added locomotion costs. Carrying loads has an extended relevance to human ecology, thus a review of the Free-Ride phenomenon detection according to the existing literature is needed. Method: A search was made in November 2021 in SCOPUS, Google Scholar, and Web of Science to identify studies comparing the energy expenditure of loaded and unloaded locomotion. Descriptive percentages were calculated with the data obtained from each study, and a Chi-squared (χ 2 ) independency test and a contingency table were applied to observe the relationship between sample characteristics, experimental procedures, and the detection of the Free-Ride. Results: A total of 45 studies met the inclusion criteria. Eighty two percent do not detect the Free-Ride phenomenon. The general detection is independent of sex, experience, load position, load size, and speed (p value >.05) although the papers detecting the Free-Ride have some common characteristics. Conclusion:The literature does not support a Free-Ride capacity, but future research testing this phenomenon should consider the load size, the load position, the level of expertise, or the speed. As the Free-Ride is not generalizable, it can be hypothesized that other mechanisms may have emerged during human evolution to buffer the energetic demands of load carrying.

“…The ergonomic assessment methodology adopted in the present research is depicted in Figure 5. It presents the purpose, method/tool The ergonomic assessment tools have been adopted by various researchers prominently for a few purposes, such as developing interventions/aids to minimize the consequences of the concerned MMH (Jung & Jung, 2003;Kumar et al, 2021), and evaluating and redesigning the task (Drisya et al, 2018;Parida et al, 2016;Torres & Viña, 2012;Zhao et al, 2022). On a similar line, the methodology proposed in the present research is based on the combination of relevant tools as adopted by the researchers.…”

“…The MMH task under study involves lifting, lowering, and carrying heavy grain bags along the paths of variable characteristics. There is ample literature dealing with risk assessment of MMH at manufacturing facilities and some other sectors; however, very few research articles (e.g., Jung & Jung, 2003; Kumar et al, 2021) are available, showing direct relevance to load handling in the agriculture sector. Various approaches available for assessment of risk associated with MMH can be classified into six types.…”

“…The first type of approach is based on the measurement of physiological parameters, such as resting oxygen consumption (VO 2 ), heart rate, blood pressure, energy expenditure, and so on. Typical applications of this approach can be found in Jung and Jung (2003), and Kumar et al (2021). The physiological evaluation approach is suitable for labor‐intensive tasks; however, it is less accurate as compared to other ergonomic techniques.…”

Manual handling of heavy grain bags is a commonplace activity across agriculture produce supply chain. In the present research, a manual material handling involving lifting, lowering, and carrying grain bags along the paths of variable characteristics is critically analyzed to explore the risk associated with it. The humans engaged in this activity are found to be facing discomfort, suffering from pain and musculoskeletal disorders, and undergoing medication for the same. This study proposes and demonstrates a structured ergonomic evaluation methodology to not only assess the level of discomfort/pain but also evaluate risk factors such as load handled, method of handling, frequency of handling, awkward postures, path characteristics, and so on. It employs a systematic multimethod approach consisting of Nordic Musculoskeletal Questionnaire and Borg Rating of Perceived Exertion, Ovako Working posture Assessment System, NIOSH Lifting Equation, Rapid Entire Body Assessment, and Key Indicator Method. The study reveals that about 94% of the sample population suffered from moderate to severe discomfort in ankle, knee, and lower back. Eight basic activities responsible for risky postures are identified. Frequency of handling, weight being handled, back bending/twisting, poor coupling, and walking surface are observed as major contributors to musculoskeletal discomfort. Carrying on shoulder is found to be riskier than carrying on back; however, the risk is found to be significantly lowered by carrying on backpack. The present study identifies the need for task redesign, proper gripping arrangements, auxiliary devices for lifting/carrying, and improvement in the path characteristics.

“…The Indonesian roof tile transportation industry remains a highly manual process involving operators carrying heavy stacks of tiles over their backs and shoulders [1,2]. If repeated for an extended duration, the action can develop musculoskeletal pain and disorders related to the shoulders, spine, and knees [1,[3][4][5].…”

The Indonesian roof tile manufacturing industry relies heavily on manual operations, specifically in transportation and inspection processes, which creates multiple issues, such as fatigue, injuries, human error, and reduced productivity. Various industries in the Indonesian industrial landscape have begun embracing a problem-solving approach known as the theory of inventive problem-solving (TRIZ) to mine solutions for industrial issues. Nevertheless, its application in the Indonesian roof tile manufacturing industry remains unaddressed. The study aims to solve manual handling issues in the roof tile manufacturing industry using TRIZ. Three observations were outlined from manual roof tile transportation and inspection, followed by the formulation of engineering contradictions (ECs). The ECs were linked with system parameters, which were used as indicators within the contradiction matrix to extract inventive principles as solution models for conceptual development. The concept included an automated system with a conveyor belt (#15: dynamics) for effective transportation, automated image capture (#28: mechanics substitution) for effective inspection, and a flipping conveyor (#25: self-service) to eliminate manual contact. Although the study addressed several issues stemming from manual operations, mechanical analysis, prototyping, and usability testing still require improvements.
