Abstract:
A traction-sheave elevator without counterweight, which is guided in an elevator shaft (1), comprising a load-conveying means (12) for carrying a load in the elevator shaft, a flexible carrying means (15) for carrying the load-conveying means, at least first and second motor-driven traction sheaves (8, 9) connected one behind the other relative to the carrying means such that the carrying means (15) defines a relative angle of wrap around each traction sheave (8, 9) of greater than 180.degree., and a tensioning device (17) connected downstream of the two traction sheaves for self-adjustably applying a requisite tension to the carrying means (15) after the carrying means comes off the second traction sheave (9) and a braking device provided for at least one of the traction sheaves (8, 9).
