Document Type and Number:
Japanese Patent JP2002167137
Kind Code:

Abstract:

To provide an elevator capable of reducing a vertical dimension of an elevator shaft top part more and of suspending a car more stably.

Since a driving device 40 is miniaturized by suspending the car 20 and a balance weight 30 with 2:1 roping and is provided in an opening between an inner wall surface 7a of the elevator shaft and an outer side vertical wall surface 20a of the car, overlap of the driving device 40 and the car 20 in the vertical direction is avoided to reduce the vertical dimension of the elevator shaft top part more. Since the car 20 is suspended with four under-car sheaves 26, 27, 28, 29 provided symmetrically front and rear, left and right with respect to a center of gravity of the car in view from a position right above the car, and a front and rear pair of suspension ropes 50, 60, the car 20 can be suspended more stably.
