Patent ID: 6854164

Claim:
An aramid-based elevator rope and termination device comprising: a socket having a longitudinal tapered passageway extending from a rear opening to a front opening, the passageway defined by first and second semi-cylindrical rope engaging surfaces converging toward one another, and transverse walls between the rope engaging surfaces, the first and second semi-cylindrical rope engaging surfaces have a constant radius of curvature; a wedge disposed within and being of substantially the same shape as the tapered passageway, the wedge having a large end, a small end, and first and second linear portions between the large and small ends; the wedge comprising a peripheral groove having a variable of radius of curvatures; the first semi-cylindrical rope engaging surface of the socket and the first linear portion of the wedge defining a first passage having an oblong cross section, the second semi-cylindrical rope engaging surface of the socket and the second linear portion of the wedge defining a second passage having an oblong cross section; and an aramid-based elevator rope for suspending an elevator having a first length in the first passage, a second length in the second passage and a third length in the peripheral groove around the large end of the wedge, the first and second passages applying a substantially constant force on the cross-section of the first and second lengths of rope, respectively, and the cross-section of the first and second lengths is oblong corresponding to the shape of the first and second passages.
