Furthermore, since the drive sheave 31 and the car-side return wheels 38 and 39 are arranged side by side at the same height in the hoistway 21, the top size of the hoistway 21 can be reduced.
[0029]
Further, since the counterweight suspension wheel 37, the counterweight side return wheel 40, and the second end portion 32b are disposed in the second plane perpendicular to the first plane, the sheaves 37, 40 The rope groove and the main rope 32 can be connected with a straight line, and the life angle of the sheave and the main rope 32 can be increased by reducing the angle of entry of the main rope 32 into the rope groove.
[0030]
Furthermore, since the drive sheave 31 and the counterweight side return wheel 40 are arranged side by side at the same height in the hoistway 21, the top size of the hoistway 21 can be reduced.
[0031]
Furthermore, since the car suspension wheel 36 is disposed above the car 24 and the counterweight suspension wheel 37 is disposed above the counterweight 25, the horizontal sectional area of the hoistway 21 can be reduced.
[0032]
Further, since the first rope stopper 34 is disposed below the upper end portion of the car 24 and the second rope stopper 35 is disposed below the upper end portion of the counterweight 25, the hoistway 21 The top dimension can be reduced. However, the first rope stopper 34 may be arranged on the upper part of the car 24 and the second rope stopper 35 may be arranged on the upper part of the counterweight 25. In this case, the rope tension can be easily adjusted from above the car 24. Can do.
[0033]
