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.
