BH77 Lifting Craning Capacity

[baronetm]

I have an L3901 tractor with a BH77 hoe, does anyone have experience or know what the lifting (craning) capacity of the boom/dipper is?

Why, I have a 44 foot long barn that was built 25 years ago, the rear 16’ is on backfilled soil with a brook 15 feet below.

During hurricane Irene the brook washed part of the original bank away which destabilized the original sub surface. The compacted back filled soils and sections of the barn floor started to slip. I have two sections of cement floor in the barn that have moved. The sections have dropped 10” on the extreme end and slipped 6” from their original position, stretch and broke the wire reinforcing between the slabs. I want to cut the 8’ x 8’ x 6” slabs into manageable pieces I can lift out and reset as tiles after the sub surface has been releveled and compacted.

I am in the process of stabilizing the bank by tiering the bank with pinned railroad ties and 10”-12” marble rip rap and boulders at the base to keep the brook from washing out any more of the original bank.
Thank you in advance for your information.

No way you're going to be able to do it in 8x8x6!
That's approxamitely 4300lbs of concreate.
The lift on a BH77 is about 2000lbs, and that's under perfect circumstances.

Have you looked into what it's going to cost to cut the slabs into smaller peices?
At 6" it's going to be very expensive!

Getting the grade right to match the bottom of the concrete is about near to impossible even with sand and as so as any weight is applied to it, the sheet will end of breaking on you.

And if you do get it to all fit back together, how are you going to tie the sheets back together?


Can it be done, yea probably but the odds are not in your favor!

NIW thanks for the response, the lifting capacity is greater than I thought it would be.

I have access to a K12 saw that will cut near 6" with carbide blades and being retired I have the time, I can crack the remaining concrete. My concern is not to have a perfect floor but one that is at least usable and will support the walls which I have already braced with steel to support. If I cut the slabs into quarters it saves me a lot of effort over cutting into eights. If all else fails and my bank supports work, I can pour a new floor later.

Thank you again.

Have you checked with your home owners insurance on this? It will not raise your rates as it is an Act of God. Least it didn't raise mine after a tornado and hail past by our neighborhood. They replaced everything that was damaged. Might be worth having an agent check it for it for you. Like NIW stated it will be nearly impossible to lay the floor back level and true.

You may want to check on having foundation repair done to level it out

There's your lift capacities. I'm guessing the job's been long since done.

Thanks for the info, no the job is not completed, I have build the retaining walls and added/placed all the rip rap.

The slabs are cut into quarters and drilled for lifting rings but I have not had a chance to lift them out and relevel the sub surface. Life got in the way with elderly family members illness that took priority.

I am hoping this summer. Thanks Again
