The present work of sufficiency selects a technological altemative for the operation of zinc ingot immersion in a 450°C molten zinc bed, which mitigates the level of occupational risk for the operators. As part of the analysis of zinc ingot immersion technologies, the Peruvian technical standard NTP-ISO 1461 was reviewed, which presents the techniques for protecting steel against corrosion by applying the hot dip galvanising process, in addition to the values of temperature, volume, level of molten zinc and safety controls for the process. It also identifies all the tasks that are generated for the operators during each stage of the process of forming the zinc coating on the steel. To identify the technological altemative that provides the most benefits to our galvanising process, some of the options implemented in similar production processes in different industry sectors related to technology 4.0 are presented; in addition, a methodology was used to identify the hazards of each activity and determine the level of risk that operators face in the zinc ingot dipping stage. The purpose of this sufficiency work is to identify the appropriate zinc ingot dipping technology for this stage of the hot dip galvanising process, in order to reduce manual operation, which generates ergonomic injuries and represents an occupational hazard. Establishing aspects of design and occupational safety to identify the motion control technology with servomotors and electro-pneumatic mechanisms; a handling system was also modelled with the AUTODESK INVENTOR software. Subsequently, the moving structures were analysed by the Finite Element Method - FEM, using the NASTRAN software and the virtual catalogue "CYMEX@ 5" was also available for the selection of commercial components for motion control. Finally, to evaluate the feasibility of the zinc ingot handling system, the results obtained are presented considering the aspects of the proposed design, occupational safety and financial analysis; the result of quantifying the economic investment to be made against the reduction of operational costs presented. In conclusion, the technologies of zinc ingot immersion in a 450°C molten zinc bed mitigate the occupational risks that operators face daily in this activity.
