trailer boom

[Taylortractornut]

I remebered the post some one put here a few months ago about a homebuilt trailed boom they saw. A few years ago I worked in Clarksdale MS and there is a tractor store outside of Bates ville that has a booom they built from a 2 ton truck frame. Its pulled with a big Ford TW15 I think. I drove by there this summer to look at some belarus engines they had. I took a few pics of this tool lifting a disc. I m wanting to build one in a few months. I saw one similar but was out of film that was built like this but the tubiing the boom was made out of had a reciver on the end for a man basket or a set of forks for placing materials. PS the dealer is Delta Tractor

I dont know what any of you want to do with this, but remember that the rear end of a TW 15 is about 2500 kg, something different than the compacts most of the people on this board have....

I think it will launch the rear end of a Kubota if you try to lift a disk harrow with one of these... /forums/images/graemlins/grin.gif

Some years ago, we used a borrowed 3 point lift boom, that worked pretty well, even without the lifting rams, it worked just on 3p lift force.
With a 3p lift boom with those rams, i would put a wheel or a slide foot on the underside of the 3p lift frame.
Maybe your top link will break, but the risk of lifting the rear end instead of the load, is a lot smaller then.

Renze A smaller berssion would be handy, also a counter weight could be used on tounge for heavy loads. A company in Argentina used to make a compact tractor boom like this that had an attach ment for a hay bale spear.
The main reason one of these booms is handy is to to place an akward load that you wouldnt want close to the tractor like a metal truss or setting poles. THe other handy thing to have with their othr boom is the manbasket attachment for there orchard and farm. They have some safety valves on the cylinders to preven a fall. They also have a remote lift so one person can use it to lift themselves to paint or weld on the pole sheds.I do agre not everyone would have a use for on that big.

A couple of downriggers on the back would help with the stability prob.

 

[markct]

then how ya gona roll it around tho if ya have outriggers on back

 

[ScottAR]

These are pretty common around here in farm country AR. Some are shop made and I think a company near here makes them as well, though I couldn't tell ya who.

As you might have read in my posting tag, i live in the Netherlands. At this side of the Pond, a popular lifting attachment is an old, used forlift mast with three brackets to convert it to tractor 3p lift use.
Biggest problem with these is that the mast is quite heavy, i think the compact tractors alike the average board member of this site have, will have trouble lifting the forklift mast alone.

I really like to watch over the borders for good ideas, and ask why people do things the way they do.

About the outriggers on the pictured boom, putting the axle of the lifting boom more to the back, or putting the attachment point of the lifted load more to the axle, would give the same effect.
The best effect is aquired when the load is lifted inbetween the wheels, but that means that you're going to need a very wide axle in U-shape.

Renze your right on the ushaped frame and stub axles. I used to have a rig I built like that for settin posts for signs and such I had to have a high lift and the abilty to hold it plumb. We also use alot of forklift fronts on farm tractors. Here there alot of old warehouse lifts like the 1200 pound capacity Clark lifts and they have light masts. Usually the forks are the highest item but when you weldthe lift arms o nthem they shoot up the price. I can buy whole lifts 200 dollars each. I have some big pallet stackers Im cuttin up now one is for a 1066Farmall and the other is for a TW15 Ford. Ithink they have a lift of around 15 feet.
Im also interested in how things are done across the pond to. I got to work with a Polish fella the other day on solving problem with Ursus tractors. I helped him figue a way to make a new brace for a loader and them made him a few kits in the shop the other day. He showed me some photos of an old farm tractor there with a homebuilt dozer blade and a winch runnin ott the pto to run blade lift.

 

[Renze]

Yes, the PTO driven winch for blade lifting is an old idea, that orginated from the old side mounted sickle bar mowers we had here 50 years ago.

I have had an MF 35 wrecker, that had an attachment on the 3p lift arm, and a cable roll under the rear axle halfshaft, so that a steel cable could go forward to pull up the side (mid) mounted sickle bar up.

I wonder why they ran the front blade from the PTO, was it an old C45 hotbulb Ursus ?? How could he keep it at a constant depth ??

 

[Taylortractornut]

Renze cant remeber the make but it had a rear pto and no power lift, it lloked like a drawbar tractor with steel wheels. They had a frame on the back with a gear reducer and a cone clutch and brake. That is a similar set up on the pcu of a cacle blade dozer. He said when you pushed the lever forward itwold release the brake for the blade to go down and hold whin it was pulled bak to the neutral. The brake drum had been made out of an old car brake drum and some home built linkages. It engaged the clutch to raise the blade. It had some out side trunions like a straight blade dozer and he had a picture of the same tractor with a different set of similar trunions with a bucket on the end of it. He said that the farmer used it in the old days to move manure and things at his dairy farm. The next time he come to get parts Ill see if I can get a copy of the pictures its black and white and shows it in use. I just has a hazy view of the loader bucket on it. im gin the process of making a pto powered post driver from a golfcart rear axle and a cable drum.

Hey Tractortaylornut, is that Polish fellow near your location, in the U.S. ?? The Ursus tractor as well ?? Or is it an Ursus rebadged as Long 900 ?? We had a C-385 A few years back. It was a hell of a machine, when the bolts connecting the diff housing with the tranny ran loose, i just drove home (without knowing the exact cause of the oil leak and funny feeling) with it and at home, my brother and i saw that it was just hanging together in the cab mounts (thats why the cab floor squeeked) and in the transmission driveshafts, the bolts were all loose, and the fitting pins were out of their holes too, there was a one inch slot between the parts. After tightening the bolts, topping up 55 liters of gear oil, i continued work and this 20 year old machine did about 1500 hours after that little accident, and died at 14,800 hours.

Renze He comes here from the home office of Ursus, the newer tractors they ship over here some of the 4 wheel drive tractors with loaders have been breaking over the axle pivots. They have a severe design flaw the local dealer has fixd several all over the US. They have several bolts that run into the thinest parts of that casting then the loaders bracket is directly behind that. the last 10 were broken in the same exacts spot I suggested to make a bracket that runs all the wat to the front to hold it equally on both sides. Im making a few repair kits fr the dealer. I should see the engineer in a few weeks when they come to get the parts.
The fella says its in his home town in Poland. Ill have to ask him again when he brings the pictures back by here to scan.
I know the feeling of having a tractor fall apart I also know its a bad feeling when you see you own transmission fluid in the road on you return trip lol.

Oh yes, the MF licensed Ursuses are imported in America...
Sorry to say so, but that is just crap. They copied an MF design but used cheaper steels.

They are no match for the older Zetor developed series Ursus sell in Poland and all over western Europe.

You might not believe this when i, as a Zetor driver say that, but everything that Ursus built on their own, has these design flaws. The MF 300 series copies they sell in America, but also the C-360 they sold mid 70's.
Those C-360 series were originally a Zetor design (Zetor 5511, 1968) but the original design was a little bit mutilated by Ursus.

I know a dealer that sold both Ursus and Zetor. He said there was a C-360 they sold, the gear of the oil pump drive broke every year and a half. They replaced it three times, then they applied a minor modification so that a Zetor gear would fit. Then, the tractor ran for years without any problems.

The best Ursuses are the bigger 80-160 hp series, designed by Zetor, (but assisted by a small team of Polish engineers, that worked in Czechia from 1964-1968)

Ursus is a good manufacturing company, but they cant take responsibility for their designs.
