<p>A traction sheave elevator comprising a drive machinery (4), a traction sheave (28) connected to the drive machinery, two diverting pulleys (5, 6), an elevator car (1), a counterweight (2) and a set of hoisting ropes (3) used to suspend the elevator car and counterweight. The drive machinery is so placed in conjunction with the elevator car that each bend of the hoisting ropes (3) around a diverting pulley or the traction sheave (28, 5, 6) along a circular path determined by the rope groove on the pulleys or sheave occurs substantially in the same direction as seen in the direction of the shafts of the traction sheave and diverting pulleys.</p> |
