Opis:
Objectives To investigate a hypothesized positive association between employment in occupations where heavy lifting is likely to occur, and the risk of ischaemic heart disease (IHD). Material and Methods Male blue-collar workers from Denmark (N = 516 180) were monitored with respect to hospital treatment or death due to IHD, through national registers over the years 2001–2010. Poisson regression was used to estimate relative rates of IHD between “workers in occupations which, according to an expert opinion, are likely to involve heavy lifting” and “other blue-collar workers.” Prevalent cases were excluded from the analysis. Results The rate ratio was estimated at 0.97 (95% confidence interval (CI): 0.94–1.00) for deaths or hospitalizations due to IHD and 1.07 (95% CI: 0.94–1.21) for deaths due to IHD. Conclusions The results do not support the hypothesis that occupational heavy lifting is an important risk factor for IHD.

Opis:
The objective of this study was to prevent occupational musculoskeletal injuries. Our workers stacked boxes of ceramics weighing 10–27 kg, making low back pain common in our enterprise. In all the stacking stations, recommended weight limits (RWL) were separately calculated using the revised National Institute for Occupational Health lifting equation. Since the boxes weighed significantly more than the RWL, we developed a new ergonomic design that completely changed the stacking process. The load put on the workers’ waist vertebrae in the new and the old stacking methods was compared to evaluate the success of the new ergonomic design, using Newton’s third law of motion. Thanks to the new ergonomic design, the load on the workers’ vertebrae decreased by 80%. Due to its simple technology and its very low cost compared to robots, the new ergonomic design can be commonly used in enterprises with repeated and constraining stacking.

Opis:
Based on the results of tests of the monorail transport system using suspended diesel locomotives with traditional transport beams and with the use of an innovative system of transport beams for the delivery of heavy loads, it was found that to reduce the dynamics of the load to the elements of the suspended route segments fastened to the arches of the arch support, it is beneficial to use the proposed an innovative technical solution that increases the reliability of the route catches to the support arches, which is important when transporting heavy loads. The new solution significantly reduces the dynamic loads to the route catches to the support arches by redistributing the load over a greater number of sections of the suspended monorail route. It has been proven that during the period of intensification of preparatory work, these technical solutions make it possible to keep to the timely preparation of new mining pillars and are perceived as a promising direction for improving the existing transport system for the mines of the region and ensuring the operational parameters of mining transport equipment at a high technical level in the specific conditions of the mines of Western Donbass.
