Tiivistelmä
The thesis objectives comprise of two major parts; one is to present design guidelines for friendlier maintenance in elevator cars, the other is to intro-duce concept designs of fixing mechanism of the lowered ceiling in special elevator car. KONE Industrial Ltd. is the commissioning organization of the dissertation. The obtained results are expected to improve main-tainability in the design of the elevator car; on the other hand, new fixing solutions of the ceiling can meet requirements of reliability, safety as well as maintainability.
In the first part, personnel from different departments within the company were involved in meetings and interviews for collecting recorded issues related to elevator car engineering and design. The collection of the diffi-culties from multiple perspectives will form the categorized guidelines with specifications and demands. In addition, the student studied and in-troduced a general approach to design for maintainability in product de-sign and development as the theory background of designing of mechani-cal components in elevator technology.
Based on the results of the first part, the second part presented fixing solu-tions for the elevator ceiling that can qualify the restrictions of operational space and high demand in reliability, safety and maintainability. In this section, various approaches and methodologies were applied to establish and develop the fixing mechanisms. For consulting and assessing, meet-ings among student and supervisor at HAMK and KONE counterparts were conducted during the idea creation process as well as design study and elaboration. In addition, factory visits did play an important part of facilitating the student familiarizing and understanding of the work.
