Is this Holland 5th wheel open?

Get a hammer and open it

 

Just by looking at it the kingpin should hit that first catch sticking out and the latch that's slightly hidden will rotate around and lock in place

Just my guess

 

It's a hook. That hook should rotate and be driven by a spring to lock into place.

Grab a lead pipe a 6 footer or more. Jam it into that thing and see if it will lock. BE READY to let that #### pipe go... it will try to kill you and anyone and everyone near. DON'T stand on top of that stupid wheel and do that pipe vertically. It will whip and throw you a hundred yards. Do it from the back... Like a trailer does.

That is a huge amount of grease. You need it in three locations, either side of the hole just ahead of the angle plates to the rear and a dab in front of the hole.

Another test to see if it's a bad hook, grab a loaded trailer take off with it onto the road. If that fifth wheel slops back and forth like a loose ... it's needing work.

 

No not open, take a crowbar and push the locking piece back over to the side and it should be ready to latch around a trailer's kingpin. Had this happen a few times.

 

I would take a stab at it and say it is unlocked. If that piece you see across the throat of the 5th wheel is the lock jaw, it probably needs a rebuild because it looks pretty f'd up IMO.

 

On a SAF-Holland Fifth Wheel, to determine if it is Locked or Open, you need to look at the Front Adjustment Bolt for the Jaws on the front leading edge of the Fifth Wheel.

If the Adjustment Bolt is sticking out and the Rubber Washer is not flush with the front face of the Fifth Wheel, it's Unlocked.

If the Rubber Washer and Adjustment Bolt is tight against the front face of the Fifth Wheel, it's Locked.

SAF-Holland purposely designed it that way so all you need to do is take a glance at it to determine its status.
