Jb grapples

I’m assuming that the rotators that many add to these grabs (tiger grips etc) would be a bit of weakness? Can you hold a load out horizontally- or is that just going to knacker the rotator?

 

[GazCro]

How did you do that out of interest? I had the plates added to mine which strengthens it a lot but suppose that might hinder some operations.

One thing tigergrips are not is the lightest grab and thats one of the things to beware of buying one which may actually be undersized.

If the right rotator is specced they should be ok within reason. My tigergrip on 9 tonner is fixed headstock for this reason i didn't want to add any weakness. Rotate would often be handy but I'll wait until its under a tilty.

That sticker for the swl has got to be the most pointless sticker going

Think the SWL is considered 120kg or something ridiculous for that machine.

that was my thoughts too. Forestry I can see the need for a rotator- but rarely feel the need for it in my line of work.

Ultimately for anyone choosing between a thumb/grapple and a proper hyd grab it wouldn't matter and could be added later. Would even up the cost difference a little as well.

One thing to note with hardox is that there are different grades I do wonder if some of these companies who have kinda jumped on the bandwagon of using are just using the cheaper grades. As you say it's not something you use to necessarily save weight but to add strength for a given weight.

If it's not Hardox...... It's not Hardox there are other brands that claim to be the same quality but there not.

I was under the impression that hardox came in different grades 400/500 etc.. not sure how much difference there is though?

Different grades of hardness. Interestingly you mention earlier the amount of wear on the plates on your grab already, well they clearly aren't the same grade as the cutting edge on my smp grader on 9 tonner. 3 year old bucket and barely any wear on cutting edge at all only very slight rounding on the very ends.

Is it a case that the harder it gets the less likely it is to spring back when bent ??

And thinking about it I bent a tine of centre on a strimech muck grab loading log rings into a chipper
Or atleast the tine didn't bend but the box section it was welded into buckled
Whereas two grapples I've use the actual tines where bent and twisted to the point they rub on another tine when opening and closing
The others I've used where just slight kink in them or one tine not lining up

Depending on the work your doing rsl do a grapple but selector grab style arms rather than tines
And they do a half bucket half grab thing aswell which is advertised as being stronger

I was meaning "brands" rather than grades etc..... Hardox 400 is a lot better than some other brands of 400 i have seen

It’s either 400 hardness or it isn’t, doesn’t matter where it comes from (apart from China, obviously). I know Earthmovers (the mag) get excited about Hardox, but there’s a lot of good buckets not made out of it. A bad welding procedure will take the hardness out of Hardox as well as any equivalent, so for a lot of jobs, unless you’ve access to a post-heat oven there’s no point paying the Hardox premium, which is considerable.

Will report back after a bit of use

To be fair his gear looks reasonably priced

If you're considering it for a micro then a grapple is the best option. Much less weight and just as importantly, less stack height. I have a hydraulic back brace on mine which makes it very versatile. Not quite as versatile as a hydraulic grab, but then I have a real one of those too, with a rotator

Although I can run my grab with rotator on the E19, I only tend to do so for scrub clearance. For wrestling heavy s**t about a hydraulic backstay on a grapple takes some beating. It lets you bring the centre of the load right back under the boom, and also load into higher vehicles than you could with a grab.

It's also much more solid carrying a heavy load, as it's braced (literally) against the boom. Can you imagine the pressure on @Storrsy 's tip links with the grab holding the rock like that and tracking??

Hi Doobin, quite a novel unit. there wouldn't be a video showing it's range of motion in your archive by chance?
