Técnicas para projetar uma linha de vida horizontal para ponte rolante

Abstract

This study aims to desing a horizontal lifeline to be installed on a single grinder-crane which is operating in steel services company. The company is not adapted the new standard NR-35 to work at a height. As the deadline to be in accordance with the standard has passed, the need is immediate. The methodology applied is a data entry in accordance with all national and international safety standards which refers to safety of working at a height. Also, to the project was applied some of the laws of physics of resistance of materials to determine which components involved with the security needed. As results, to obtain the numerical values of the forces involved in anchoring which provide all the data required for fitting the horizontal lifeline in analysis. With all the data defined a drawing was made showing how it has to be built and a list of commercial parts to be purchased in order to complete the project. It is recommended that this work serves as technical guidance to professionals involved with safety, and to use it in their lifeline projects, either horizontal, vertical or provisional. Also, it is recommended to students of as a research resource.
