Abstract

PURPOSE: To improve workability and safety at maintenance by arranging an opening/closing mechanism in a machine room for leaving an entrance open through automatically standing a hatchway cover based on an operation of a maintenance switch at the maintenance.
CONSTITUTION: In order to leave an entrance 9 open for maintenance, a face flat screw is loosened and removed, and a maintenance switch is brought to a maintenance mode. Then, a conveyer for passenger is stopped, a pump 22 of an opening/closing mechanism 21 is operated so as to force-feed working oil to an oil feed pipe 23, a hydraulic jack is filled with the working oil so as to project a plunger 24a by a pressure action, and a hatchway cover 10 is rotated in the perpendicular direction to open the entrance 9. When the hatchway cover 10 is brought to the upright state, a notch in a hinge 16 is engaged with a latch 17 so as to mechanically hold the upright state of the hatchway cover 10, a full-open detection switch 26 detects the upright state of the hatchway cover 10 and stops the pump 22 which is forcefeeding the working oil to the hydraulic jack 24.
