That’s what I just said. You will not find those numbers anywhere on the actual mecanil site. Let me know if you do and I’ll eat crow. They’re not there. Gives you psi of grip. That’s it. Doesn’t tell you how much you can lift. Same thing I said above. You might have missed that one in the barrage of posts. Lol
 
Would you consider this huge 80% of your radius? Lifted off the ground. Veeeeerrrryyyy slowly

Actually didn’t realize that was not mecanils website till I read closer

True but if you go by the load chart and it says 100% is 3000lbs then 100% is 300lbs on weight. The rest is configuration. Boom configuration doesn’t give you the ability to pick more. Boom angle and radius does.

I am 100% agreeing with you. But he doesn't have a load cell or lmi. All he is talking about is his remotes percentage of capacity readings which is based off of Hydraulic pressure, not a actual weight reading. Your chart and angles trumps all. (btw my Fassi does not show all the angles like palfinger). You have to know the weights your picking, or be playing it really safe,period. Percentage of capacity isn't knowing the weight of the picks.

It’s relative. Speed has nothing to do with it. Am I in chart or not. I don’t know your chart but I know what others charts look like because they are the same as mine and what they’re taking I can’t but they do. I don’t know what your numbers are so I have no opinion but once you find out what your manual is good for you’ll be the best judge of that

We are calling things differently. Percentage of capacity is what the crane can lift per chart. What you are referring to is the percentage of max pressure in a cylinder. Regardless how you have the crane configured(what pressure where at what angle) you still can’t exceed chart that’s what I’m saying.

When he tells me he’s at 90%. I’m assuming he’s at almost 100% chart not what his pressure is on x cylinder.

Ok

But I think he is just reading that 80% on his crane remote....which only shows pressure %

It is my understanding that all knuckleboom remotes only show pressure % unless you are using a load cell of some type.

I’m not saying anything bad Todd. I was told what I was told when I took delivery. I haven’t seen anything more than that on numbers on mecanils site. If these are the numbers they should have them available for all of us because it’s over 2000lbs difference than what I was told was the max squeeze pressure. By no means am I saying you’re wrong. I’ve never seen those numbers anywhere else is all

Exactly why o have a load cell because it’s not a reliable tool for lifting unknown loads. That’s my biggest gripe with my
Machine. I never lift without the load cell. I know what I can lift and it’s a matter of figuring out the best boom configuration. I hit 100% on the remote quite a bit because I set my main at 80d and left it. When I started changing the main angles my maxes dropped across the board-on the remote. It didn’t like the pressure on the main cylinder but I was golden on what it the crane could actually pick up. Does that make sense?

Correct. The pressure is a comparable to weight unless you are just over extended. Not the same of course. That’s just what I heard.
 
I’m not trying to be a jerk. Just trying to share what I’ve learned and probably not explaining it very well and by no means am I slamming Todd. He’s a super valuable resource to all of us. Just wondering where the disparity in the numbers are.

But it’s kinda not. I’ve been lifting say 2000lbs. The remote is reading 100% but the load chart says I’m good for 3500. It’s how I have the booms configured. It doesn’t like the angles but it’s fine with the weight. I tweak some boom angles and drop to 70% and all is well. What I have found is the main boom angle in relation to the outer boom was putting more pressure on the main cylinder and it didn’t like it. Keep your main at 70 and drop the outer to flat. Created a 90d angle between the main and the outer. Drop the main and soften the angle and the numbers drop to next to nothing. It’s not the weight. It’s the angles creating pressure one one cylinder instead of distributed more equal on 2 cylinders. Does that make sense? Sorry guys but I’m whipped. I’ll check back in tomorrow. I’m no expert but this is what I’ve found through trial and error.
