Diseño y construcción de un sistema de elevación con mecanismo neumático para la empresa Ciauto Cía. Ltda.

Abstract

The problem with this project was the handling and transport of tyres in the area, due to the fact that the stacking of these objects is carried out manually, causing musculoskeletal efforts in the operators and a prolonged execution time, slowing down the productivity of the assembly plant. The technical work was developed through the collection of information with the help of the operators in the corresponding area to understand the process of stacking and transporting the tyres with a range of 75 lifts during the eight hours of daily work. Subsequently, the pneumatic design was implemented to a lifting mechanism whose zero gravity type operation improves the ergonomics of this process and speeds up its execution, additionally it meets the transport needs proposed within the company; and finally, the structural design of the bridge crane was developed, verifying the results in accordance with the CMAA-74 and AISC Design Guide 7 standards. The structure was complemented with the mechanism for its execution as a whole to allow its free movement through the work area. At the end of the work, it was found that the time of stacking and transport of tyres was reduced compared to the initial state of the project, which improves productivity in the area of assembly of the company CIAUTO CÍA. LTDA. Likewise, the improvement in ergonomics that is produced thanks to the structure that includes the pneumatic mechanism, benefits the occupational health of each of the operators.
