Abstract
A rope of a lifting device, more particularly of a passenger transport elevator and/or freight transport elevator, an elevator, and a method for manufacturing the rope are disclosed. The rope includes an unbroken load-bearing part, the profile of which is essentially of rectangular shape, and the width of the cross-section is greater than the thickness and which load-bearing part comprises glass fiber reinforcements and/or aramid fiber reinforcements and/or carbon fiber reinforcements and/or polybenzoxazole fiber reinforcements and/or polyethylene fiber reinforcements and/or nylon fiber reinforcements in a polymer matrix material. The long sides of the cross-section of the load-bearing part include one or more grooves symmetrically or asymmetrically in the longitudinal direction of the rope, which grooves divide the load-bearing part into smaller parts.
