The present invention provides a safety system for checking the lower part of an elevator. A cage is elevated at a predetermined height to maintain and check a driving part installed in a pit which is the lower space of an elevator. As it is stopped, the height of the cage is maintained. Thereby, a worker easily enters an elevating path pit and also an accident generated by the descent of the cage due to malfunction can be prevented in advance. So, safety can be improved. Because the reliability for products increases, the worker can improve working efficiency and productivity at the same time without anxiety. |
