Broken wires in what I am guessing is preformed rope - see how flat they are laying...hard to catch with the
"rag in hand" technique of rope inspection. The blade of a small pocket knife will "click" as it runs over a break.

As you can see the wires in every other strand are either regular lay or lang lay...
perhaps an attempt at a non-rotating rope?
I have not seen this type of rope construction in the elevator trade.

This is several feet of discarded lang-lay rope.
Wires in a lang lay rope rotate in the same direction as the strands.
Can you see any areas on this rope that might be bad?

 Retaining Clips & Anti-Rotation Devices 

From: A17.1-2007/CSA B44-07 - Safety Code for Elevators and Escalators

2.20.9.5.4   When the rope has been seated in the wedge socket by the load on the rope, the wedge shall be visible, and at least two wire-rope retaining clips shall be provided to attach the termination side to the load-carrying side of the rope. The first clip shall be placed a maximum of 4 times the rope diameter above the socket, and the second clip shall be located within 8 times the rope diameter above the first clip. The purpose of the two clips is to retain the wedge and prevent the rope from slipping in the socket should the load on the rope be removed for any reason. The clips shall be designed and installed so that they do not distort or damage the rope in any manner.

From: A17.1-2007/CSA B44-07 - Safety Code for Elevators and Escalators

2.20.9.8 Anti-Rotation Devices. Following the completion of the rope socketing and any adjustments of individual shackle rods as provided for in 2.20.9.2, means shall be provided to prevent the rotation of the suspension ropes without restricting their movement horizontally or vertically.

 Suspension Means

Please Note:

The code does not specify the size of the wire rope (if wire rope is used) necessary "to prevent the rotation of the suspension ropes"...this anti-rotation means appears to be 1/8 inch aircraft cable.
