| 摘要 |
The invention relates to an elevator comprising a hoistway (S), an elevator car (1) and a counterweight (2) vertically movable in the hoistway (S), a drive machine (M) comprising a drive sheave (5), a roping (3) comprising one or more ropes (4) between the elevator car (1) and the counterweight (2) and passing around the drive sheave (5) and suspending the elevator car (1) and the counterweight (2). The drive sheave (5) is positioned in the hoistway space which is between a hoistway wall and the vertical projection of the car the drive sheave rotation plane being at least substantially parallel to the hoistway wall (W). Said rope(s) (4) is/are belt-like, each comprising one force transmission part (15) or a plurality of force transmission parts (15) for transmitting force in the longitudinal direction of the rope (4), which force transmission part(s) (15) is/are made of composite material comprising reinforcing fibers (f) in a polymer matrix (m), an in that the reinforcing fibers (f) are carbon fibers, and in that said one force transmission part (15) or each of said plurality of force transmission parts (15) has width (w,w') larger than thickness (t,t') thereof as measured in width-direction of the rope (4,4'). |
