摘要: An elevator safety arrangement and a method for implementing spaces in an has mechanical device which can be set to working position ensure sufficient space the shaft electric system identifying operating state of device. controller comprises means measuring total resistance series circuit. The includes reading number landing doors open by detectors fitted conjunction with doors, car If it is established that greater than open, then setting into ‘person shaft’ preventing operation elevator. during equal been position, allowing maintenance operation.
