Resumen

Introduction. Manual lifting and carrying of loads that are equal to or greater than 25 kg are considered high ergonomic risk for causing musculoskeletal disorders in any activity where there is no load sharing or mechanical assistance. Objective. This research applies the use of a steel mask as a mechanical aid to attenuate musculoskeletal disorders in the workers of the company Ecovasti S.A. who lift and move the jars of alcoholic beverages in the delivery of the product to the customers. Methodology. A preliminary analysis of the lifting and moving of loads in the manual dispatch of alcoholic beverage jars was made using Snook and Ciriello tables to find the maximum acceptable weight and the level of ergonomic risk, then the key indicators of pull and push method (KIM PP) was applied to demonstrate the ergonomic improvement by implementing the help of a mobile steel forklift. Results. The preliminary study with the Snook and Ciriello tables indicates a maximum load handling weight for lowering, lifting, transporting and dragging: 11.9 kg; 7.79 kg; 16.43 kg and 25.67 kg respectively, considering male gender, with a protection percentage of 90%, maximum distance traveled of 8 m, load weight of 23 kg per jug of alcoholic beverage, average transfer height of 0.8 m, with a frequency of 15 transfers per hour. The result of the application of the ergonomic improvement with the use of the key indicators of pull and push method (KIM PP) was a value of 1, which corresponds to a low ergonomic risk with a low probability of physical overload. Conclusion. The result of the application of a steel trolley for the manual transport of alcoholic beverage jugs in the dispensing to customers attenuates the level of ergonomic risk to low risk values and could help prevent musculoskeletal disorders.
