Uncoupling levers - How do they work

"NDT bloke to come in on Monday morning and crack test them."

 

Actualy he is probably going to flourescent penetrant inspect them but you got the point across even if the terminology was wrong.

Cheers

Funny, I understood Mark perfectly.  We use "non-destructive testing" in the Canadian Armed Forces on aircraft components, on main armaments of the battle tanks, and on propellar shafts and blades in the Navy...among many other applications.  And, I always understood that they were looking for structural defects, cracks among them.

G'day Crandell,

I'm glad to see you understand plain English!

The thread seems to have been over-run by smartarses who want to split hairs over semantics - because they have no substantive arguments to counter the facts that have been presented.

Cheers,

Mark.

How is the terminology "wrong"? The couplers are tested for cracks, hence we use the term crack testing. What other terminology would you use?

And, actually, our NDT bloke uses mag particle flaw detection, not dye penetrant.

"Pulling the pin" while it started with link & pin coulpers still applies today as every locomotive coupler has a top lock lifter. So when you operate the uncoupling lever it pulls the lock lifter part of the way up out of the coupler. The part of the lock lifter that raises up out of the top of the coupler while not round does looks like a pin.

The correct name for testing for cracks in a coupler is "Magnetic particle inspection" or as it is commonly called Magnafluxing after the Magnaflux company that pattened the procedure and equipment in the mid 1930's.

Husband: Hey honey, could you pick me up some pencil lead for my mechanical pencil.

Wife:       You moron. It's not lead it is graphite. They haven't used lead in pencils in 50 years.

Husband: Well where I come from they call it lead.

Wife:      They do everything backwards where you come from.

Husband: I know 50 people that work at the pencil factory and they all call it lead.

Wife:      I found the copy of the patent and it clearly states that graphite is used instead of lead because of the health concerns.

Husband: It doesn't matter what it's made out of. IT'S STILL CALLED PENCIL LEAD!

Wife:      YOU ARE A MORON JUST LIKE YOUR FATHER!

Husband: WELL YOU COOK JUST LIKE YOUR MOTHER!

Not all locomotives have Top-operated couplers.  Our E-units have the pinlifter (uncoupling lever) on the bottom.  When using the uncoupling lever, it raises the toggle.  When making a joint, you look for the toggle ("pin") to drop.  By the rules, you should then stretch the joint to make sure it is good.
