Abstract: A traction elevator system including elevator ropes, and hitch plates for terminating the elevator ropes. At least one of the hitch plates includes first and second vertically spaced, aligned support levels, with the rope terminations defining first and second complementary patterns, respectively, selected to reduce the maximum fleet angle by providing components thereof in the axial direction, with respect to the sheave axis, and transverse thereto, and by reducing the cross-sectional area occupied by the ropes at the hitch plate.

Abstract: A friction driven tachogenerator having a friction drive wheel in contact with a movable member. The tachogenerator is compliantly and frictionlessly mounted, and at least one pressure roller is disposed in tangential, rolling contact with the friction drive wheel. The pressure roller biases the friction wheel against the movable member to provide a predetermined contact pressure between the friction wheel and movable member without applying a significant load to the shaft and bearings of the tachogenerator. The compliant and frictionless mounting of the tachogenerator is devoid of friction sources which can interfere with the sensing of velocity oscillations by the tachogenerator.
