  • In order to check traction of the elevator, the load-test is positively necessary on the inspection of elevator in Korea. So actual loads are used in the elevator car for the load-test. However, some of advanced countries in Europe, for example Germany, are using the alternative method with no load test instead of traditional load-test. Commonly hydraulic elevator, compared to passenger elevator is mainly used for loading heavy weights. It requires a great deal of labor to carry out load-test. The reason is why we developed a new inspection skill for the load-test of hydraulic elevator without actual loads. The results of studies show that the new method of the load-test can be replace the traditional load-test.

  • Recently, many of people concentrates on the importance of elevator safety system for the elevator accident of traction machine malfunction. Also, IT convergence has enlarged various field for the effort of enhanced traditional industry. In this paper, we define that the safety is to minimize the dangerous factor, then explain the rules of elevator installation. Through the expert's decision we could find out the dangerous factors are poor check, malfunction of amalgamative and user's mistake. We propose the IT convergence managing system for the effective alternative method of elevator safety system.
