Abstract
PURPOSE: To ensure the safety by expanding and shrinking an expansion and shrinkage mechanism of a floor landing position adjusting means in accordance with an output of a floor landing detection means when an elevator car arrives at a floor and compensating a floor landing position while brake of a winch is applied. CONSTITUTION: When a car 3 is apart from a door zone, for example, a cylinder 15 is shrunk and cranks 13, 14 are in an elongated condition, a detection plate 20 of an arm part 19 turns on a position detection switch 21, rotates a pump 17 in the direction of rising, and opens a solenoid valve 18 to elongate the cylinder 15. On the other hand, while the cylinder 15 is elongated, the reverse operation is done, and a length is controlled so that the cranks 13, 14 are positioned between position detection switches 21 and 22 by the detection plate 20. Moreover, when a loading capacity is large and the car 3 lowers from a specified floor landing position, a detection switch 24 is turned on by a detection plate 23, and a floor landing position adjusting device 6 operates in the same way to adjust so that the detection plate 23 is positioned between detection switches 24 and 25. In this way, the compensation for expansion and shrinkage of a main rope can be done while brake is applied.
