Replacing a Knuckle

Postby webenda » Fri Feb 17, 2017 1:01 am

I have always wondered what a railroad knuckle weighs. Now I know.

You're lucky you're not posting on OGR. Some guy over there would be wanting SHELF couplers! :lol: :lol: :lol: :lol: :lol:

They're heavy enough you get to hopping real well if you drop it.

I'm completely surprised. I should have thought they were far heavier than that. I've seen women who clearly had rear ends heavier than that, though larger. :mrgreen:

You have to hold their rear ends the same way, just keep your hands further apart.

Duly noted. I'll exercise caution when approaching both.

The EOT weighs about 40 lbs depending on the type

Depending on the size and type of coupler ,Couplers weigh Roughly 400 lbs to 700 lbs

Train Guy 3 wrote:I would say most of the knuckles I've pick up before are in the 70-80 lbs range. 40 lbs sounds about right for a EOT. A knuckle you no from the start is going to be heavy to handle, EOTs are east to pick up just very arkward to handle and store.

The above, latest conversation just demonstrated to me that I have been thinking of a "knuckle" as a term for the whole coupler, which is what I imagined weighing several hundred pounds (see carknocker1), and not lift-able by any one man, unassisted by equipment, not 80-ish lbs..
interesting.

However, I should imagine doing so on a regular basis for work at a RR yard to lift a knuckle or a coupler would not be desirable, huh.

You get used to it, as with all things, there's a best practice involved. I usually found that getting everything out of my way and making the install in a single movement worked best. It's the stopping mid-point in the operation that really puts the stress on the ol' mid and lower back.

Whothehell would allow themselves to be abused by a job that required them to lift such a thing, no matter the technique?!

(Yet, I can recall seeing men work as hard as that while standing over, next to, or in hellholes, literally , as molten metal flowed very , very near to them .)
