Abstract (en)
[origin: EP2022744A1] In an upper portion of a hoistway, there is arranged a drive unit having a drive sheave which is driven to rotate around a rotation shaft disposed along a vertical direction. First and second main ropes serve to hang a common car, and hang a common counterweight. In the upper portion of the hoistway, there are arranged a first car side deflection wheel that guides the first main ropes to the car, a second car side deflection wheel that guides the second main ropes to the car, a first weight side deflection wheel that guides the first main ropes to the counterweight, and a second weight side deflection wheel that guides the second main ropes to the counterweight. Also, a horizontal defection wheel for deflecting the direction of the first main ropes is arranged at the upper portion of the hoistway. Portions of the first main ropes between the drive sheave and the first weight side deflection wheel are wrapped around the horizontal defection wheel. The first and second main ropes are respectively wrapped around the drive sheave in such a manner that at least a part of a force received by the rotation shaft of the drive sheave from the first main ropes and at least a part of a force received by the rotation shaft of the drive sheave from the second main ropes are counteracted with each other.
