Summary
Two devices reduce physical strain for bricklayers by raising work materials. This ergonomic improvement lowers lumbar compression force, making the physically demanding job safer and more comfortable.
Area of Science:
- Occupational Health
- Ergonomics
- Construction Safety
Background:
- Bricklaying is physically demanding, involving frequent trunk flexion.
- Workload is highest when handling materials near floor level (0-50 cm).
- Repetitive strain injuries are common in the construction industry.
Purpose of the Study:
- To evaluate the effectiveness of two practical devices designed to mitigate physical strain in bricklaying.
- To assess the impact of these devices on perceived comfort and biomechanical load.
Main Methods:
- Field experiments were conducted to assess the impact of two ergonomic devices.
- Measurements included perceived comfort and estimated lumbar compression force.
- Observations were used to supplement quantitative data.
Main Results:
- The devices provided a 50 cm raise, which was perceived as comfortable by bricklayers.
- Estimated lumbar compression force was significantly reduced.
- Observational data corroborated the positive effects on workload.
Conclusions:
- The evaluated devices offer a practical solution for reducing physical exertion in bricklaying.
- Despite limitations in field experiments, the findings suggest these ergonomic improvements are recommendable.
- Further research and adoption of such devices could enhance bricklayer safety and well-being.
