Abstract

PURPOSE: To improve safety by energizing a detecting idler on an elevating chain and controlling a ball screw by a selenoid brake in accordance with an access switch signal when the elevating chain is disconnected. CONSTITUTION: When a detecting means 1 is pressing an elevating chain 42 in a normal condition, an access switch does not actuate with specific space maintained relative to the access switch but a ball screw 36 is rotated by a reversible motor 39 through the elevating chain 42, a driven side sprocket 41 and the like and a passage body 21 makes an elevating movement together with a passage supporting frame 23. Should the elevating chain 42 disconnect, a detecting idler of the detecting means 1 isolates to the free position side by the spring force so a solenoid brake 26 is actuated by the access switch detecting it and checks the rotational motion of the ball screw 36 subject to load and inclined to turn on its axis. Thus the passage body can be prevented from making a fast descending and safety can be upgraded.
