View Full Version : Looking for a logjack that lifts but doesn't turn the log

All of them seem to be based on the peavy and made sorta like this:

The problem is that the logs to be lifted are actually large limbs with all the smaller branches still attached. There's no reason to turn them, and they want to flip back over when they're lifted.

So, I want a tool that just lifts the log (limb) by raising it and moving it sideways as it settles on the jack. Does such a tool exist? Would simply removing the fixed point make it work like I want?

I would either modify the one in your picture or make one from scratch. You would need to remove the point at the end and make a curved scoop which you would push under the log. When you pry down with it, the scoop would pick it up and pull it towards you and lift it without rotating it. The swivel hook would keep the log from sliding down towards your hands.

I don't know you are located. I know that Lee Valley (leevalley.com) has several different implements for lifting and moving logs.

Why not just trim the limbs up and work on them. When finished there just work your way down the the trunk in sections. Or maybe this is the justification for a new tractor with with a front loader.

We want to cut off the large diameter part of the limbs without getting the saw in the dirt. The rest of the limb will be dragged (without any further trimming) to a pile for burning . A front end loader is used there to lift it onto the pile.

Why not just pry the large limbs up a bit, then place some short cut up pieces crosswise underneath for them to settle back down upon, thereby holding them up off the ground?
With judicious placement, relative to the planned cuts, to prevent binding the saw, it's a piece of cake.

Sounds like you want one of these:

The tree doesn't want to move so the wheels will roll under it to acomplish the lift.

Way back in my other life, I worked for a power line construction company. We built distribution power lines. One of the steps involved assembly of the power pole with cross arms, insulators, braces, and any other hardware needed for the particular application. This was all done on the ground before hoisting it up and planting it in the hole.
We had to lift the top end of the pole up on a stand before assembly. These poles weighed several hundred pounds. We had a D shaped stand made of angle iron about 18 across. It was placed next to the pole at about of the way from the bottom and then using a Peavey one guy could rock the heavy pole up onto this D shaped stand. Thus allowing work on pole top.
The pole was not rotated when this operation was done. One person could lift a several hundred pound pole up off the ground.
NOW , what was it called? As I remember we called it a pole-gin. But when I searched google they refer to a pole gin as a lifting arm attached to a pole. I will keep searching and see of I can find the proper name. I think is just what your looking for.

Without the teeth and the grippers. Otherwise it's just a different style peavy. Personally never needed more than just a peavy or other logs to prop with. I've done my share of felling. Sometimes the saw touches the dirt a little, no big.

Not the one I was looking for, this one looks like some thing you could build.

This is the thing I was looking for to lift poles.

So if I understand you correctly you only want to lift it a little bit maybe 5" max.

I would use the farmers best friend - a farm jack!!!!

There is a hole on the bottom of the saddle to connect a chain.

It will be wobbly, but, you are going to lift a little to get the log up out of the dirt.

Use at your own risk.

Lugnut's suggestion of the pole jack is getting closer, but the stuff to be lifted isn't nearly heavy enough to require hydraulics. A lever handle will probably be enough for all but the largest limbs. Something that slips under the log, then lifts it up without turning it is what we need.

I put together this jack with stuff in the scrap bin for a trial run:

The foot of the jack can be used as kickplate to get the prong under the limb. Lowering the handle will get the log up, and the second prong will keep it steady. We'll see how it works.

One possible problem is the limb might want to move back, and that would make the handle swing up. That could get ugly.

Tripod and chain block?
