Abstract:
The invention relates to an elevator comprising a hoistway, a vertically movable elevator car, a vertically movable counterweight at least one first rope interconnecting the car and counterweight and passing around one or more rope wheels mounted in proximity of the upper end of the hoistway, the weight of the elevator car being arranged to exert an upwards directed pull on the counterweight via said first rope, and the weight of the counterweight being arranged to exert an upwards directed pull on the elevator car via said first rope. The elevator further comprises a motor-driven winding device connected at least with the car or the counterweight for exerting a vertically directed pull on said only one of the car and counterweight for thereby changing the balance between the car and counterweight.
Abstract:
A hoisting device rope has a width larger than a thickness thereof in a transverse direction of the rope. The rope includes a load-bearing part made of a composite material, the composite material including non-metallic reinforcing fibers, which include carbon fiber or glass fiber, in a polymer matrix. An elevator includes a drive sheave, an elevator car and a rope system for moving the elevator car by means of the drive sheave. The rope system includes at least one rope that has a width that is larger than a thickness thereof in a transverse direction of the rope. The rope includes a load-bearing part made of a composite material. The composite material includes reinforcing fibers in a polymer matrix.
Abstract:
In a rope of a lifting device, particularly of a passenger transport elevator and/or freight transport elevator, the width of which rope is greater than the thickness in the transverse direction of the rope, which rope includes a load-bearing part in the longitudinal direction of the rope, which load-bearing part includes carbon-fiber reinforced, aramid-fiber reinforced and/or glass-fiber reinforced composite material in a polymer matrix, and which rope includes one or more optical fibers and/or fiber bundles in connection with the load-bearing part and the optical fiber and/or fiber bundle is laminated inside the load-bearing part and/or the optical fiber and/or fiber bundle is glued onto the surface of the load-bearing part and/or and that the optical fiber and/or fiber bundle is embedded or glued into the polymer envelope surrounding the load-bearing part, as well as to a condition monitoring method for the rope of a lifting device.
Abstract:
A rope and an elevator. The rope comprises a core, an outer layer of strands, comprising at least four outer strands, and an elastomeric coating creating at least the outer surface of the rope.
