Elevator

A counterweightless elevator comprising:

• a hoistway;
• a car vertically movable in the hoistway;
• one or more suspension ropes;
• a rotatable drive member, provided on a first side of the car and engaging said suspension rope(s), each of the suspension rope(s) having a first rope section on a first side of the drive member and a second rope section on a second side of the drive member, each rope section being connected to the car, wherein said first rope section passes from the rotatable drive member down to a first rope wheel mounted on a bottom of the car, and is then guided upwards to pass over an upper rope wheel provided on a second side of the car, forming a first rope loop suspending the car, said second rope section passes from the rotatable drive member to a second rope wheel mounted at a lower end of the hoistway, forming a second rope loop which is suspended by the car via a third rope wheel mounted on the bottom of the car, and each of the first rope wheel and the second rope wheel has an axis of rotation which is orthogonal to an axis of rotation of the rotatable drive member;
• and
• a tightening device arranged to tighten the second rope section, wherein the second rope section is guided from the second rope wheel to the tightening device, and from the tightening device to the upper rope wheel provided on the second side of the car;
• wherein each of said rope(s) is belt-like and comprises a load bearing member or a plurality of load bearing members, which load bearing member(s) is/are made of composite material comprising reinforcing fibers embedded in a polymer matrix, which reinforcing fibers are carbon fibers.
