Use of a platform trolley to transfer spare parts for heavy machinery, as an ergonomic aid in winemakers of the company CRCC

Abstract

Introduction. At present, a progressive increase in musculoskeletal disorders has been noted in people who work in copper mines, especially winemakers who lift and transfer loads of materials, heavy equipment, and spare parts. Objective. This research analyzed the use of a platform cart as an ergonomic aid, for the transfer of materials in the warehouse of the company CRCC, using the Snook and Ciriello table, which is based on the ISO 11228 standard. Methodology. This work is prospective, correlational, qualitative-quantitative, since an instrument will be implemented to improve the job of a winemaker. First, the maximum acceptable weight was determined under normal working conditions, considering the worker's posture and the characteristics of the load lifting of the CRCC company cellar position, using the Snook and Ciriello tables that collect the maximum acceptable weights recommended for the load handling, with sustained ascents and descents and the force when pushing or pulling the load. To deepen the study, an evaluation of the lifting and transfer of the load was carried out, after the implementation of a 4-wheel steel platform car with a load capacity of 300kg, using the KIM-PP Key Indicator push and pull method. Results. From the application of the Snook and Ciriello tables in initial conditions, a value of 12.82kg of maximum acceptable weight was obtained, considering: a) manual transport of the load, b) the load is transported by hand, c) 40kg of weight medium of the load, d) 10 transports per hour, e) inadequate grip, f) vertical distance from the ground to the hands is 110cm, g) distance of transport of the load of 8.5m. After the implementation of the ergonomic measures, a score of 5 was obtained, which represents a low ergonomic risk level of 1, taking into account: a) 68m push and pull distance, b) use of a platform cart, c) 40kg weight of the load, d) speed of movement <0.8 m / s, e) trunk slightly inclined forward, f) floor with small unevenness. Conclusion. The result of the use of the flatbed car helps significantly in the transfer of the cargo of the CRCC company winemakers, determining low risk levels.
