5.0 PROCEDURE

NOTE - Sections of this procedure may be performed out of order and sections may be omitted,

based on device features and device specific instructions provided by data sheets or

procedures.

Inspection results are to be documented on procedure data sheets.

require dismantling the hoist. Covers and other items normally supplied

allowing component inspection should be opened or removed for inspection.

Deficiencies found during inspections listed below must be carefully examined

and determination made as to whether they constitute a hazard. Failure of any

limit/safety device is grounds to STOP and contact a FWS to generate a work

package for repair.

Attachment 2 – Wire Rope Replacement Criteria

The following criteria determine when a wire rope is no longer acceptable for service:

Notes:

Use of rotation-resistant rope must be approved by the manufacturer of the

equipment on which it is used. Application of rotation- resistant rope requires

special installation procedures, higher design factors, and special inspection and

maintenance procedures.

This section refers to replacement of rope used with steel sheaves and drums. The

user shall contact the sheave, drum, or hoist manufacturer or qualified person for

removal criteria for ropes operating on sheaves and drums made of material other

than steel.

1. In running ropes, 12 randomly distributed broken wires in one lay or 4 broken wires in one

strand in one lay

2. In rotation-resistant ropes, two random broken wires in six rope diameters or four randomly

distributed broken wires in 30 rope diameters shall be sufficient reason to consider not using the

rope)

3. One outer wire broken at the contact point with the core of the rope, which has worked its way

out of the rope structure and protrudes or loops out from the rope structure

4. Wear of 1/3 the original diameter of outside individual wires

5. Kinking, crushing, birdcaging, or any other damage resulting in distortion of the rope structure

6. Evidence of heat damage from any cause

7. Reduction from nominal diameter greater than those listed in the following:

Rope Diameter (inch) Maximum allowable reduction from

Nominal Diameter (inch)

Less than or equal to 5/16 1/64

More than 5/16 to 1/2 1/32

More than 1/2 to 3/4 3/64

More than 3/4 to 1 1/8 1/16

More than 1 1/8 to 1 1/2 3/32

8. Attention must be given to end connections. Upon development of two broken wires adjacent to

socketed end connections, the rope must be re-socketed or replaced. Re-socketing must not be

attempted if the resulting rope length will be insufficient for proper operation.

Two directions of discontinuities are labeled on drawing below as "P" and "T." Discontinuity P parallels

the contour of hook and is considered nonserious in nature and does not require removal. Discontinuity

T is transverse to contour of hook and is more serious in nature. Discontinuity T, when occurring in
