Abstract(s)
A evolução no domínio das tecnologias dos equipamentos de elevação com velocidade reduzida para pessoas com mobilidade condicionada – home lifts, e o crescimento do número de equipamentos instalados é, atualmente, uma matéria que exige bastante atenção por parte das entidades competentes no sentido de minimizarem os riscos relacionados com a segurança das pessoas que utilizam este tipo de máquinas e, adicionalmente, garantirem o cumprimento dos requisitos aplicáveis. Se, numa perspetiva, os home lifts devem ser concebidos cumprindo os requisitos da Diretiva “Máquinas” com aposição da marcação «CE», por outro lado são instalados e mantidos em funcionamento sem qualquer tipo de inspeção inicial e/ou periódica que avalie o seu estado de funcionamento e de segurança. Este paradigma impõe o desenvolvimento de uma metodologia que permita a avaliação de segurança e integração dos requisitos aplicáveis. O principal contributo deste trabalho reside no desenvolvimento de uma ferramenta de avaliação de conformidade de home lifts – designada por HOLINSPECT, composta por uma metodologia de avaliação e uma aplicação informática para aplicar a metodologia. A metodologia é assente em duas componentes fundamentais e complementares, nomeadamente a inspeção da máquina e a análise da documentação técnica. A metodologia considera os princípios das Diretivas «Nova Abordagem» que complementam os requisitos definidos na legislação e as especificações técnicas estabelecidas na normalização para definir os requisitos de avaliação de conformidade. Além destes, também se integraram os requisitos relativos à acessibilidade das pessoas com mobilidade condicionada. Na metodologia são propostos três procedimentos de avaliação, métodos e critérios de avaliação, soluções para corrigir as não conformidades detetadas, graduação do nível de risco e a emissão do relatório de avaliação. A metodologia foi integrada numa aplicação informática, que serve de apoio à avaliação de segurança dos home lifts e pode ser utilizada pelas diversas entidades avaliadoras. Possibilita a realização da avaliação junto do home lift através de um processo digital. É utilizada como interface para o utilizador, permite o registo e/ou a consulta dos dados relativos às inspeções e a emissão de um relatório de avaliação da conformidade. Os três casos de estudo apresentados nesta dissertação permitiram inferir acerca da importância da avaliação de conformidade do home lift, a necessidade de automatizar o processo através da aplicação informática e a validade da ferramenta global, que possibilitou a validação dos equipamentos com base na legislação atual.
The evolution in the field of technologies of lifting equipment with slow speed for people with reduced mobility – home lifts, and the growth in the number of installed equipment is, currently, a matter that has required a lot of attention by competent entities in order to minimize the risks related to the safety of people using this type of machinery and, in addition, to ensure compliance with the applicable requirements. On one hand home lifts should be designed in compliance with the requirements of the "Machinery" Directive with the «CE» marking affixed, on the other hand they are installed and maintained in operation without any type of initial and/or periodic inspection to assess their operation and safety. The main contribution of this work resides in the development of a home lifts conformity assessment tool - HOLINSPECT, composed of an assessment methodology and a computer application to apply the methodology. The methodology is based on two fundamental and complementary components, namely the inspection of the machine and the analysis of the technical documentation. The methodology considers the principles of the «New Approach» Directives that complement the requirements defined in the legislation and the technical specifications established in the standardization to define the requirements for conformity assessment. In addition to these, the requirements regarding accessibility for people with disabilities were also integrated. The methodology proposes three evaluation procedures, methods and evaluation criteria, solutions to correct the non-conformities detected, grading the risk level and issuing the evaluation report. The methodology was integrated into a computer application, which supports the safety assessment of home lifts and is applicable to several assessment entities. It allows the assessment to be carried out with the home lift through a digital process. It is used as a user interface, allows the registration and/or consultation of inspection data and allows the issuance of a conformity assessment report. The three case studies presented in this dissertation made it possible to infer about the importance of conformity assessment to the home lift, the need to automate the process through the computer application and the validity of the global tool, which made it possible to validate the equipment based on the current legislation.
