I found my BX BH limit

[Tommy V]

I was trying to lift a 15 foot long electric pole and put in in a hole. I strapped the pole to the bucket with chains and a strap near the bottom of the pole. The plan was to pivot the pole from horizontal to vertical and put it in the hole. The result was the pole 2 feet off the ground horizontally and a blown bucket curl hose. I guess I will need to find a different way to get the pole in the hole. The popped hose was not to too difficult to remove and the cost is not too bad, about $35.

Not sure how you can blow a hose doing anything with the BH. I use the curl to fight huge limestone ledges here. It is **** on the tractor and I can spend an hour literally flopping my tractor against the ground without hydraulic failure.

To handle a pole that size you will need a HUGE TLB, along the lines of a Ford 555.

I would think a 15 footer to be not too bad. 30-40 footer would be another story.

Blown hose, you must've had a sudden stop or the like.

Better a hose than cylinder packing or valve, a lot more work to fix (maybe not dollars though).

Good luck with pole installation.

Thats odd. The relief should've kicked in before blowing the hose unless the hose had a problem with it.

I could be wrong, but I think if you are say lowering something fast and and let the valve snap to shut, there is no place for the presure to go as I think the relief valve is on the presure side??

Probably a weak spot or other defect in the hose.

Of course that can happen for this reason. If you have enough weight on a mechanical device that is pushing on a ram, like in a hydraulic cylinder, the force can overcome the pressure of the system/hose and destroy something. That is similar to ramming your bucket into a load of dirt, and then wonder why the cylinder failed or the hose busted. Even the relief valve can not relieve the pressure fast enough. A hydraulic spike can be very high. You will either blow the circuit, or twist some metal. Rules are rules.

Of course...similar to ramming your bucket into a load of dirt...

I've done that over and over and over and over. Yesterday, I 'cut down' a 2" caliper maple by running into it with the FEL. Didn't come down, so I did it again. Still didn't, so I got more of a running start. STILL didn't come down so I hit it lower and curled while pushing forward in low range 4WD. Then it came out.

Such is the way of things with my tractor. I'd be a little bummed to have a hose blow just for using the BH. I guess I have close to 200 hours on the tractor with BH attached, so a hose could eventually go. And the 'bouncing' thing makes sense.

But how do you load the FEL with dirt but to drive it into the pile first? Faster the better!

Of course I'm kidding a little here, but not much. These things aren't exactly built to a 1.05 factor of safety like an airplane or something. If you compare the raw weight of weld beads on my tractor to the same on my truck, I'll bet there's 2x more on the tractor...

If the hole is big enough, you can put a 10 or 12 in board in the hole. Put one end of the pole at the hole, then hook the pole to your bucket, and lift. The end of the pole will hit the 12 in board, and as you lift, it should just slide in.

What color was the stain on the parachute, red or brown?
