I have a B7800 with a LA402 FEL.
I want to lift the concrete cover of my well and have been trying to figure out how to attached a hook or an eyebolt to the top of the FEL. The top bar is rolled and does not appear to be substantial enough to support a hook or an eyebolt without some backing. Any suggestions?

A lot of folks have chain hooks welded to the top of their buckets. It's recommended that some gusseting be welded inside the bucket in the rolled area directly under the hooks to reinforce the area. ....

I welded the chain hooks with backing plates, no gussets, but when I lift I use both hooks to help spread the load. ....

If your bucket's cutting edge has holes in it, use the center hole to attach a chain either by inserting the hook (if it is an open type) or an eyebolt or simply bolt the chain to the bucket. I wouldn't on yours (but have on mine) dropped a Grade 8 bolt stacked with washers into the 1/2" hole on my skid steer's bucket an used it as traler hitch ball to move tralers around the yard (my trailers have a lot of tongue weight so there is no worry about them coming off).

In a pinch I've tilted my bucket back and hooked the chain onto the cutting edge--the only worry there is if you a have the bucket raised and you have not a lot of machine weight, if the chain slips to one side or the other you WILL flip the machine--got the T-shirt and a missing chunk of the seat cushion. LOL If you're ever in a situation where you feel you're ready to overturn--just drop the loader arms as fast as you can to counteract the momentum and center of gravity.

Another option is use the 3-pt hitch to pick up that cover.

I have had hooks welded on all my buckets, each side and middle. Each time there was a section of angle iron welded the length of the top edge of the bucket to weld the hooks to properly reinforce or as previously mentioned gusset the bucket. Do it right the first time and you won't regret it later. You can go broke saving money. ....

The big problem you will have in reality is not where to put the hooks, but what and how they will lift.

First off, capacity period, the information I have says a B7800 with LA402 loader is 1,060 pounds at the bucket pivot pins, and 760 pounds at the bucket center at full lift height. I suspect in the real world, the FEL wouldn't lift 500 pounds. "Specifications" are usually written based on hypotheticals such as peak pump output times, peak horsepower, times blah, blah, blah, not 'real world' actual measurements.

The second problem is tractor design, the front axle pivots. If the load is not exactly centered the relatively narrow tractor will tend to go over sideways as more is lifted and less load remains on the fixed rear axle.

The far better way IMHO to lift anything like that is using a "gin pole" on the 3pth.

Best of luck. ....

I think Murf has a good point. Even if your bucket is capable of its specified lifting capacity you need to be vary careful and aware of its balancing and stability issues with lifting a lot of weight forward. I have a L3540 which weighs quite a bit more than a 7800 and when doing that kind of lifting I either will make sure my BH is attached or an implement weighing at least 500# or more is attached to the 3 pt. I use a 3 pt fork lift instead of loader forks for the reason Murf states. Also using only the middle hook on heavy lifts helps keep the load centered. Only use the hooks on each side when you need things to keep from flopping around, but not to secure a heavy load. ....

Jack up one side of the cover. Scoop the bucket into the gap. Attach an L-hook to the far side of the cover and make fast to the top of the bucket so the cover won't fall away. Then just lift.

Otherwise the problem is not just attaching to the bucket but also to the cover (unless you have four eye-bolts in it already). ....

Good plan, but it won't work.

A 36" well tile lid weighs over 600 pounds, 613 in the case of the company we use.

A B7800 with a LA402 FEL has a rated lift capacity 1,060 pounds at the pins, and 760 pounds at the "middle of bucket". That's a ~30% decrease from the pins to the middle of the bucket. If you extend that out another foot or more, and decrease by another (only) 30% you're down to ~530 pounds.

Now you have a 'lift rating' of ~85% of what you need to lift.

And that's assuming the machine can actually lift what it's 'rated' for, which IMHO is never going to happen.

Best of luck. ....
