Cable Specs

1/2" 6x25 IWRC Right Lang Lay

Hi, DWC7.
And, - - - I am open to correction here but I think it is supposed to be 1/2" X 6/19, that is 6 wires with 19 strands in each wire. It is also my understanding that Cat only ever used this same wire rope in all of its cable controlled units, regardless of size.

Just my 0.02.

1/2" IWRC 6/19 is what's called out in the O & M Manual

Hi Team,
what is given above is correct.
Scan from a No 30 CCU OMI for the actual words from Yellow Father--for the doubters.

EDIT for later Specs.

WELL, we have found that there are newer Specs. from Big Yellow Father and are currently as follows :-

Newer cable spec. :-
1/2 inch, 6 X 25 filler wire, right Lang lay, independent wire centre, preformed improved plough steel type.

The welding of the ends of the rope they refer to is that we used to wrap several turns (Lashing style) 1/16" welding wire around the cable about 3/4" in from the end and cut --melt-- the cable thru with an oxy cutting torch and so doing this welded the strands together and so help stop unraveling during threading--especially when doing a Scraper bowl sliding sheave block in the goose-neck crossbeam-- for the fist time in the New Equipment shop.

Old cables we replaced by similarly welding/melting the old and new cables together to reeve the new cable in by pulling the old cable out it drew in the new one--broken scraper apron cables were a fun job- not--lots of grease and dirt in the goose-neck crossbeam and fish hook cable wire shards everywhere.

Only cable spec., that I am aware of, that varies from this is used for the actual Wheel Scraper Apron lift cables--this would be given in a Scraper OMI, of which I do not have any off.

Cheers,

My #25 and #127 cable control manual and 435 scraper manual call for 6x25. But maybe todays standards have been updated to 6x19?

Seems to be the later CCU's used the 6 x 25.

Hi Team,
indeed there are changes to the cable specs. as in the Grey OMI's from my 117 and 116 Cable Control books as you both have outlined.

Newer cable spec. :-
1/2 inch, 6 X 25 filler wire, right Lang lay, independent wire centre, preformed improved plough steel type.
