lifting logs

Sat, 10/17/2009 - 18:47 — DarrylAndCindy

block and tackle types necessary to lift big fir logs. I have 2 ton rope pulley on each end of log. Not strong enough to lift log when pulling rope. Any suggesting would be greatly appreciated

Lifting logs

I use an electric winch. Take the haul lines straight down to a directional pulley anchored directly under the block/tackle allowing the haul lines to turn 90 degrees and run horizontal along the ground. Anchor the winch on a tree close enough for the winch (fully extended) to reach. Attach haul lines to the winch and GO...ridley

block and tackle`

make sure the rope is going cleanly through the sheaves. you can't afford the friction for lifting, and if you wear out your rope, you'll have a dangerous situation.

However logs are super heavy. I would suggest getting a snatch block (single pulley) and mount it at ground level. Then use an atv or pickup or chevette... whatever you have to pull the rope. remember, you are only getting 6 to 1 mechanical advanatage with the BnT. at 2000 lbs, you still have 333 lb that you have to apply (assuming zero losses). you can't do that, but henry ford can.

Lifting heavy logs

My logs are 50 feet log and up to 2 feet in diameter at the big end. Since mine are standing dead (beetle-kill) they are quite a bit lighter than if they were green, but I still can't lift the big end with block and tackle. What I've done in the past is pull the rope at the big end with the electric winch on the front of my Jeep. That lifts it with ease. Then for the lighter end, I'd stand on top of the wall and tie a loop with a bowline knot at the appropriate place on the rope. Then, while sitting in the loop, I'd jump off the wall. This lifts the small end very nicely. This method can lead to tragedy, though, if there was to be any equipment failure. I have placed over 40 logs by myself doing this. But, DON'T do it!!
I've now figure-out that if you run the ropes thru a single pulley at the bottom of each corner, you can pull up both ends simultaneously using one winch, car, truck, tractor, etc.
