Boom Pole on 2 inch Receiver

[BobRip]

Nice job. I would recommend that you attach a steel support cable to the tip of the boom, and the top of the vertical 2 in receiver. If you happen to pick up a large weight with out it, something is going to bend, or pop a weld or bend your QA plate. I built a similar pole for my tree snipper. You can get more lift by inserting the pole in the top receiver, and using the tilt to raise and lower the pole. I have a picture of one like this one if I can find it.

Thanks for the input. I had considered putting on a cable, but was unsure of the actual need. The post material has pretty thick wall. I will see what I can do about the it. Clint Blake is supposed to bring me some in. Any ideas on how much stress will be on the cable? Is 1/8 inch thick enough?

BobRip,
Where do you get your materials (steel) from? And how much does it cost?
Thanks,
Abe.

I got the materials from a local metals recycling yard. It was the only piece like it. I tend to go to the yard, see what is available, think about how I would use it, and them come back and buy the materials. Don't wait too long, because it may be sold. I paid about $10 (don't know exactly because I picked out pieces and got a total price). We found some thick wall square tube that goes very nicely into a 2 inch receiver. Clint Blake and I bought all that they had. I have used some and have plans for the rest. They have not gotten anymore back in.

That i/8 cable should do it if secured good. A quick way to add the cable is to use a turn buckle and hook on one end, and a hook on the other end. Loosen the turn buckle to install, and tighten the turn buckle to make the cable tight. Do you have something to clinch the cable ends together?

I saw one unit that had hooks about every 18 in for lifting different loads.

I don't have a cable clinching device. Can you describe or do you have a picture of such a device. Perhaps a blob of weld on the end?

More hooks would be easy. I will add if needed.

I finished the long boom pole today....

Picture number two looks like some kind of single manned tank!

I've been contemplating making a 15' to 18' long arm to hold an inexpensive electric chainsaw. I figured I would lock the switch on and control power by flipping the on/off switch of the power invertor. That would let me trim a lot of branches without my arms falling off with one of the hand ones you can buy. Plus I think I could build one cheaper than the one's I've seen at HomeDepot.

You guys think but welding four 4' pieces of 1.5" angle iron (angle facing up) with maybe four 1' flat pieces spread evenly "boxing" it in would provide sufficient strength for that distance?

Bob, This picture shows a little device that you could add to your boom pole, and give you variable lifting points. With this unit, you can't use the support wire.

On securing the wire, some of the wire comes already made up with what looks like a metal tube crimped on the wire. They simple run the cable through the metal tube, and make a loop and run it back through the tube, and crimp with large cable crimpers.

This picture shows a heavy duty a-frame boom. You could probably use steel electrical tubing with some bracing for a light weight frame, and add your chain saw. That electric chain saw probably pulls around 5 amps. Will your inverter handle that?

Since it looks like a tank, Clint Blake will have to have one.

I was thinking about the chain saw also. That will be one pretty good size inverter and the load on the PT battery would be very high. You could bring along a dedicated battery. The battery current into the inverter is 10 or 12 times what the saw current would be. The starting current on the saw would be probably at least 3 times the running current. At least a 2 or 3 KW inverter (continuous rating) would probably be needed. Check with the inverter supplier to make sure.

I don't know about the angle irons. If it was not strong enough, you could add the cable above it.

Neat device. I will probably install the support wire, and it is little trouble to weld extra hooks on.

This is a boom I made to do kind of what you want to do, closed it's 125" extended it's165" work's well on the pt
