ABSTRACT:
A traction-type elevator includes a driving sheave (19) arranged in an upper portion of an elevator shaft, cage sheaves (6, 7) arranged at an angle with respect to the driving sheave (19) and mounted on a support beam (5), multiple (or turns of a rope) ropes (17) hung on the cage sheaves (6, 7) and the driving sheave (19), and a hanging rod (10) for hanging a cage from the support beam (5). In this traction-type elevator according to the invention, one torsion coil spring (16) is arranged between the cage side and the aforementioned support beam (5) appropriately so that the aforementioned hanging rod (10) is inserted through it; the two ends of torsion coil spring (16) are attached to a cage side and a side of the support beam (5), respectively. The support beam (5) can effectively rotate to relax torsion in the ropes (17), and it is possible to suppress generation of vibration by the torsion. Also, the torsion coil spring (16) can play the role in damping vibration without shifting outwardly.
