Our question has to do with how to mount the grapple to the bucket itself. Originally this type grapple was bolted to the top lip of the bucket itself but i'm thinking that might not be the strongest way to mount it.
If you look how some companies attach to the sides of the bucket i'm wondering if you think this may be an advantage strength wise. Does it make a difference if the support tube is round or square when it comes to overall strength?
Anyone else have any input on how to make this grapple quick attach to the bucket, or should I just settle for pulling the 3 lift arm pivots with the rear cylinder pivot to lift off the majority of the grapple when it's in the way?

I would add a full length brace and put drop ears on each end with Pin holes to match the side of the bucket. You would need to reinforce the pinholes in the bucket. Maybe 4 locations.? 2 on top and 1 on each side. It would be quick release but I think you would get some movement unless your pins could use a taper fit on the keeper????
I doubt this makes any sense but a drawing is coming when I can

Not to complicate things, but I'd consider attaching the grapple to the quick disconnect so it could be used with both forks and a bucket. With forks you'd have to remove the guard but it would enable picking up and clamping more stuff that you'd be able to pick up with just a bucket.
You could attach the guard to the grapple to ensure safety.

Dareen I had considered your idea however when a large truck comes in here to be off loaded sometimes the pallets are stacked two high. The top pallet is very close to the roof of the truck. It's kind of a get under it and gently lift an inch or two to get it out of the way so I'm concerned that the grapple would more than likely be in the way more than it might help. Maybe still it could be quickly pulled off the pallet forks in that type situation. I'll consider that idea, thanks....
John I eagerly await your drawing. /forums/images/graemlins/grin.gif

I built my grapple using the side mount. It worked out well. When I got a second bucket. All I had to do was drill holes in side of new bucket. Here is a link to some pictures of it. Click Here. Thread has links to some other Grapple threads that may help you.
I can remove the arms and cylinder without taking the cross piece off by removing four pins.

I like your idea, and will take it into consideration if I add the grapple, which I'd like to do. /forums/images/graemlins/smile.gif

Ron do you think there are any advantages to using the round support tube over square? Wonder which would be stronger?
I like your set-up by the way, nice job indeed.

hi8ya PR:
the round would be a bit stronger (not by much) but the sq would be easier to work with, align and attach now and in the future...
I'll eventually build one for my tractor too, no time now but one day I will. anyhow the side and top of th ebucket would give you extra strenght for sure. most bolts have more shear resistance than they do tear out strenght.
MarkM Jville ohio all under water /forums/images/graemlins/blush.gif /forums/images/graemlins/frown.gif anyone have any ideas how to attach PONTOONS to their tractors? /forums/images/graemlins/tongue.gif

Square or rectangular tube would make the grapple you are looking at easier to make. I used round because that's what I had. I doubt if it would make any difference in this application.

I think there are 2 advantages to the side mount. The sides of the bucket are aligned to provide strength in shear rather than bending which is an improvement, plus the side mounts are at a radius from th <font color="black"> </font> e pivot point closer to the tips of the grapple to reduce the bending moment transferred to the bucket mount.
Also, the widest possible bolt pattern for the side mount will be strongest.
Hope that makes sense.

Usually square tubing is much stronger for a given tube size and wall thickness.

These guys Virnig make nice looking ones. If you look at the endplates, there is only one bolt that goes through the square tube to attach to the endplate. So, two bolts and hoses and it's off. And, all you would need for your forks is two more endplates. JackIL originally posted the link and I've been saving it to build my own (someday).

Dale the single bolt mounting on that grapple is very interesting. We originally though about using the round tube mount but you guys just about have me convinced to use square instead.
Square tube has merits as far as being easier to work with and I'm now considering that saddle type mount that you sent me a link to. Also going to take a real good look at our pallet forks and possibly consider this as a multi-function grapple. If we change our plans now before we start running bead maybe we can kill two birds with one stone. /forums/images/graemlins/grin.gif
Thanks for all the suggestions so far guys, please keep them coming.

What will be the main thing that you will use the grappler for? I got to say that a side mount would be stronger.

Deerlope the bucket grapple will mainly be used for clearing downed trees on our surrounding property. We borrowed one a couple of weeks back and did more work in the couple of days that we had it than we could have done in a week without it. Unfortunately John, the neighbor that lent it to me wasn't giving it up for good without a fist fight. Think we would have lost that fight! /forums/images/graemlins/grin.gif
I figure it will be a nice addition to the TC-40D package.

I have done a lot of welding and steel fab work and it does not matter a whole lot how you mount it. The fel is always subject to a lot of side strain so the grapple would be also. Whatever is eaiser for you to do I guess is what matters.
