MACHINE ROOM-LESS ELEVATOR |
摘要 |
<p>A machineroom-less elevator in which a counterweight is vertically moved behind a cage, with the cage and the counterweight being suspended in a jig back manner through a first and second diverting sheaves. In this machineroom-less elevator, a sufficiently large vertical stroke of the counterweight can be secured, while a durability of a hoist rope is improved. In addition, since no tensile difference is generated in respective parts of the hoist rope, vertical vibrations of the cage are prevented when the cage restarts a vertical movement. A traction sheave is disposed on one of right and left sidewalls of an elevator shaft. A first diverting sheave is disposed below and sufficiently apart from the traction sheave, and a second diverting sheave is disposed on a top of a rear wall of the elevator shaft. The traction sheave is disposed to be inclined relative to the sidewall such that a rotational axis thereof extends from the sidewall of the elevator shaft to the rear wall thereof, when viewed vertically from above.</p> |
