I found a 4' / 4000 lb lifting strap that fits across the bucket hooks. Now I'm looking for the right size steel ring to slip on the strap to chain to. Should work good with my short chain.

I normally weld a hook dead center on the bucket. If I were to put two on I would do it like you have, looks to be a bit inside the loader arms. Nice system you are developing.

That'll work. But now you need to look into a removable boom so that you can lift higher. I've seen several threads on that subject.

When you suspend a load from a sling that way you are multiplying the force on the sling. As you approach having the sling horizontal and the load line approaches a right angle with the sling the load on the sling approaches infinity. Course that won't happen. You need to take this into account when you use a "4000 lb" sling. Another danger is that as the sling loop end approaches a 90 degree angle from the plane of the hook, it will have a nasty tendency to jump off the hook. All good arguments for a third hook in the center, as suggested by magicheater.

I swear I'm not being a safety cop - just making some observations.

I did the same setup on the bucket on my 2320. 1 hook on each side but almost in line with the lift arms. We took a piece of 1/4" plate and cut it to fit inside the bend on the loader underneath the hook so we don't have to worry about the top plate bending down. One of those things that you can't imagine how you lived without it before.:thumbsup:

Just remember to never rig so that nice new strap is accross the cutting edge of your bucket. I'm also in favour of a 2" receiver in the middle of your bucket. Then you can slip in a lifting hook or make up a short boom.....

Nice looking FEL Hooks and Sling! Most hardware stores have rings that you could use or just buy a shackle. That strap in the picture could probably lift your tractor (not legally) with a 30 degree lift angle without breaking. Just don't let anyone under the load!!!

Regarding your sling in the picture I have lifted many thousands of loads commercially with Synthetic Slings and have never broken a sling or accidentally dropped a load. If that sling has a rating of 4k lbs then the actual breaking point of the sling is many times the rated capability. All the slings that I've worked with had a 5 to 1 safety factor. OSHA Standards 1910.184 & ASME 30.9 were the final word regarding slings used during commercial lifts but they left everything up to the FAA unless there was an accident.

FYI: There is a loss of lift capability formula for OSHA Approved Synthetic Slings that are used at an angle of less than vertical. Just eyeballing the sling in the picture I would guesstimate a sling lift angle of approximately 35 degrees which would reduce the 4,000 rated sling to a safe "legal" lift of 2,296 lbs. I'd probably derate it to a 30 degree lift angle and allow a 2,000 lb load. I always kept a Sling Angle Chart with my lift helicopters and with my lift ground crews for drop in visits from the FAA especially when lifting in densely populated areas such as going vertical 500' between the high rise buildings of San Francisco and other West Coast Cities. I normally used a 125' to 150' Wire Rope (Cable) connecting the helicopter's main hook to the Synthetic Lift Slings holding the load. Now if I was lifting out in the country without the FAA (Fanatics Against Aviation) prying eyes I'd use common sense.

I personally would use a Synthetic Sling connected to your load instead of a chain to prevent damage to the load but for personal use you use what you have. I use short lengths of braided nylon fire hose around the slings to protect the sling from sharp edges.
