Abstract: The invention relates to a method for inspecting quality and/or condition of an elongated composite member, which is a load bearing member of a rope of a hoisting apparatus, such as an elevator, or a precursor of such a load bearing member, the method comprising providing an elongated composite member; and changing the temperature of said elongated composite member by heating or cooling said elongated composite member via a flank thereof; and scanning said elongated composite member from a lateral side thereof with a thermal imaging device after said changing of the temperature; and creating thermographic images of said elongated composite member.

Abstract: The invention relates to a traction wheel for an elevator for driving plurality of belts, comprising a central axis; plurality of circular rim surfaces side by side in axial direction against each of which a belt can be placed to pass; and circular guide flanges on axial sides of each rim surface for guiding a belt placed to pass against the rim surface. Each of said guide flanges comprises a circular array of guide parts, plurality of which guide parts comprises a guide surface portion for guiding a belt, which guide surface portion is movable towards the central axis. The invention also relates to a drive machinery and an elevator implementing the traction wheel.

Abstract: The invention relates to a method for condition monitoring of a rope of a hoisting apparatus, and to an arrangement for condition monitoring of a rope of a hoisting apparatus, preferably of an elevator for transporting passengers and/or goods.

Abstract: An elevator arrangement, comprising at least one rope connected with an elevator car; a rope wheel arrangement comprising at least one rope wheel around which the rope passes turning around an axis, which extends in width direction of the rope; and a rope position detector arranged to detect displacement of the rope over at least one limit position and to trigger one or more predetermined actions in response to detecting displacement of the rope over a limit position. The rope is arranged to pass around a rope wheel turning around an axis, which extends in width direction of the rope, and the rope position detector is arranged to detect displacement of the rope over a limit position in thickness direction of the rope at a detection point, and to trigger one or more predetermined actions in response to detecting displacement of the rope in its thickness direction over the limit position, said limit position being on the opposite side of the rope than said rope wheel.

Abstract: A method for installing a hoisting rope into an elevator system includes providing a rope reel storing a hoisting rope; and thereafter unwinding a section of the hoisting rope from the rope reel; and arranging the section of the hoisting rope unwound from the rope reel to pass from the rope reel to a rim of a drive wheel of the elevator and around it such that it rests against said rim; and thereafter rotating the drive wheel with a motor for driving the hoisting rope to run around the drive wheel.
