slowing down a claw

[scootr]

Need help slowing down the single cylinder on a new titan pallet fork grapple. The aux control on the bobcat is a momentary toggle type switch. This control is pretty much on or off. So I need to slow this thing down. I was wondering if inline flow restriction is the way to achieve this or ? Any help appreciated.

Yes it is. Go with an adjustable one so you can fine tune it easily.

You get one that adjusts in both directions or get two that adjusts in one direction only so you can adjust for different speeds on closing and opening. Although, I assume you're mostly interested on adjusting the closing speed on the grapple.

My grapple is a single lid with a 2" cylinder. I installed a restrictor in one line. You can adjust the speed faster by drilling it out SLIGHTLY.

That looks like what I need! Does it matter which line I put it in?

I installed my restrictor on the non-rod end of the cylinder being that that side flows more oil for every inch of travel. It should not matter though.

Grapple - Grapple needs flow restrictor?!

I dont know what the difference is but the website said to use htis model to slow the cylinder equally in both directions regardless of which line it was in. That would be okay with me... Aparently the one you linked only works in one direction, is that correct?

Yes. The one I shared, only works in one direction. The one you shared, works on both directions.

Great! Thanks for your help guys.

If there is ever any chance of anything getting ‘stuck’ to the lid id try to keep at least the up travel at full speed, because it irritates me to not be able to ‘shake things off’ and have to dismount the machine and crawl over all kinds of tripping hazards to work it loose. My .02.
