    Abstract: The invention relates to a drive machinery for an elevator, the drive machinery comprising a rotatable drive sheave for driving plurality of ropes of the elevator, and a motor for rotating the drive sheave; the drive sheave comprising a drive sheave body rotatable around a rotational axis; and plurality of rim arrangements mounted on the drive sheave body side by side in direction of said rotational axis, each said rim arrangement defining a circular outer rim for transmitting traction to a rope, said circular outer rims being coaxial with each other. The diameter of the circular outer rim of one or more of said rim arrangements is individually adjustable for enlarging or reducing the turning radius of a rope passing around the circular outer rim in question. The invention also relates to an elevator comprising said drive machinery.

    Abstract: The invention relates to a belt-shaped rope of an elevator having opposite lateral sides facing in thickness direction of the rope, at least one of the lateral sides being shaped to have elongated ribs that are disposed adjacent each other in width direction of the rope and extend parallel with the longitudinal direction of the rope. Each said rib has a first flank face for contacting a flank face of a rib of a rope wheel, and a second flank face for contacting a flank face of a rib of a rope wheel. Each said first and second flank face is shaped to have an arcuate cross-sectional profile, and said first and second flank face are shaped to arc to such steepness that the angle defined between their tangents is acute, and the surface material of said flank faces has shore A hardness more than 85 and less than 100. The invention also relates to an elevator arrangement as well as to an elevator, implementing the aforementioned belt-shaped rope.
