Decreasing energy input however becomes a problem, which can be solved in all energetic countries. Mechanisms effectively are not using qualitatively and correspond at the functions, but they have to do it in less expense. Today in Lithuania is using more than 5 thousand passengers’ lifts, they were begin to use before 25 years and now they are exceed producer in recommended time. This work purpose is to analyze Šiauliai city elevators’ system work, to evaluate damage for mechanisms’ using and to find out originate reasons and security mechanisms using choice for the following days. The statistics information about elevators’ breakdown analysis was done by the program packet STATISTICS. The elevators’ breakdown origin duration was repartitioned by log - normal and the term between breakdowns by exponential. They are normal in exploitation time, but chance of none breakdowns (0,28), the short time thought breakdowns (1030 hours) and a lot number of breakdowns show that the third period comes with obsolescence and wane processes. The dispatching influence was evaluated and developed that this manner makes better indexes but the basics node control is needed. Elevators’ using expenses were valuated. The huge part of expenses 86,7% dispatching and 87,6% not dispatching lifts compose repair expenses. Users have damage by outage of lifts, which make 0,2 % and 0,7% expenses. The repair reasons are not trust the mechanisms. The security of using to days technologies need to increase: the magnetic and inductive position, the bigger security relay. We need to change old to new and common duration between breakdowns can lengthen about 6 occasions. It can decrease the service of personal number between 2-3 awaking brigades to one. All these factors may decrease general passengers’ expenses to use lifts. |
