PART 2 PRODUCTS

2.1 WIRE ROPE AND SOCKETS

Provide wire rope and sockets which are the standard product of a manufacturer regularly engaged in the manufacture of wire rope, and that essentially duplicate products having been in satisfactory use for at least 5 years prior to proposal evaluation. Submit manufacturer's qualifications statement.

2.1.1 Type of Wire Rope

The wire rope must be of the following type:

2.1.1.1 Strand Configuration

6x19 Seale

2.1.1.2 Lay

Right, lang

2.1.1.3 Diameter

0.75 1.25 inch or as required for the approved hoist design, with a tolerance of minus and plus 5 percent

2.1.1.4 Finish

Plain

2.1.1.5 Minimum Breaking Strength

49,600 129,400 pounds for 0.75 1.25 inch diameter wire rope, other diameters as approved.

2.1.1.6 Material

AISI 304 stainless

SECTION 35 01 70.13 Page 3

2.1.1.7 Core Type

Independent wire rope core

2.1.1.8 Pre-Formed

Yes

2.1.2 Pre-Stretching

Submit Pre-Stretching Procedure. Pre-stretch the wire ropes before attaching their end terminations. This is done by subjecting them to three cycles at 40 percent of its nominal strength. Hold the 40 percent loads for 5 minutes with 5 percent loads for 5 minutes between cycles. A method of dynamic pre-stretching may be proposed.

2.1.3 Wire Strength and Ductility

Perform testing in accordance with FS RR-W-410 to verify wire strength and ductility. Submit test results.

2.1.4 Pre-forming

Provide pre-formed wire rope, and perform testing in accordance with FS RR-W-410 to verify pre-forming. Submit test results.

2.1.5 Stress Relief "(Wrapping Test)"

Stress relieve the wire rope, and perform testing in accordance with FS RR-W-410 to verify stress relief. Submit test results.

2.1.6 Weld Distribution

Wire joints in any strand must not be closer than 18 inches in any strand.

2.1.7 Strand Pitch Length

Not be less than 4-1/2 times the nominal rope diameter.

2.1.8 Core Strand Wires

The number of wires in the core strand must be equal to or greater than the number of wires in the other strands. Use the same material as the wires in the other strands, or use a material with a lower tensile strength.

2.1.9 End Terminations

Submit shop drawings, as specified. The wire rope end terminations must be an open spelter socket type with poured epoxy resin. Spelter sockets must be suitable for use with stainless steel wire rope..

2.1.10 Tension Testing

Submit rope tension test report. Perform a tension test to verify the wire rope meets the accepted industry standards for nominal strength.

Test two rope samples to failure to be sure the expected performance level has been met. Perform the test using suitable tension testing equipment and by qualified personnel. Submit certification of rope tension testing

SECTION 35 01 70.13 Page 4 device. Cut the rope samples to no less than 3 feet of length. The test will not be considered valid if the failure occurs less than 2 inches from either socket or holding mechanism. Relative speed between the machine heads must not exceed 1 inch per minute.

2.1.11 Attaching and Proof Loading Terminations

The manufacturer must attach the end terminations after pre-stretching the wire rope. After their attachment, proof load the wire ropes at 40 percent of nominal strength of the rope. Measure the length of the wire ropes to the nearest 0.01 inch at a load of 19,800 pounds. Submit proof load of terminations test report and measured rope lengths.

2.2 LUBRICATION

Submit manufacturer's literature for factory and field lubricant. The field and factory lubricants must be compatible. Lubricate the wire ropes at the manufacturing facility. Apply the lubricant with equipment capable of forcing the lubricant between the rope wires, including the center strand.
