Technically that would be a CV joint.
A monster CV joint!

Hate to have to grease that one.

You'd be there awhile.

Reminds me of the 'driveshaft' in my old forklift ! Though I bet that one still has ALL it's needle bearings in it AND a LOT easier to work on !
curious , what is 'Big Blue' ??

 

[Henro]

Wonder what the need was for that?

Perhaps to eliminate alignment concerns between two units connected together?

My curiosity joins with GVJay's...

Curious that there is no machine guarding, anywhere??

 

[GreensvilleJay]

guards ??? hahahaha... I wouldn't want to be anywhere in the room if that it broke !!!!

At least the ujoints are 'synced' ! It'd NOT be 'fun' to tell the boss,oopsy. has to be taken all apart.....

It's not the breaking, it's the getting sucked in to it.

On the other end it's connected to a squirrel with a serious attitude in a cage.

Yep…I was wondering they argue over Lucas vs mobile one in the break area at work? Or maybe over manual vs cordless vs pneumatic grease gun?

Looks like a hoist drum for a mine shift. You can see one of the brake shoes in the back ground.

Looks more like a double cardan joint.

Looks more like a double cardan joint.

Yes, and also referred to as a CV joint by many.

I don't care what you call it, with only 7" of ground clearance, it was going to be a royal pain in the but to get the allen key grub screws out and then pray to the great god of forklifts that the 'driveshaft' WOULD come out. I still have the u-joint crosses here, forklift is gone, dodged that job...

 

[lugbolt]

double cardan joint just not the type I'm used to seeing

 

[skeets]

I wonder what mine that one is for?

 

[chim]

Here's something that looks similar. Winders for mining?

Mechanical-new winders
