Appreciate you creating an actual illustration using a load cell, especially appreciated that it was short so that I could easily review it. Thanks
Great explanation, simple to the point and no music. 👍
No matter how many times I see this explained it still amazes me.
Excellent demo. Concise and to the point. No fluff. Thanks! 👍😊
I use your snatch blocks every day at work. I was unaware of this thank you for the info
U saved my job today bro
I learned to make my hook on the roof stronger than the weight of what I was about to lift
Thanks for sharing
Great demo! So simple in concept but not obvious till it's explained. Thanks!
This is great. I will save it for all of the off road videos that use snatch blocks on the anchor claiming there is mechanical advantage. Thanks for the demo. One note, the winch force or power is not increased. The load limit it is able to pull is increased by the mechanical advantage. There’s a slight difference but important to understand.
When he asked "how much load is on my snatch block" I guessed it was 240 but having no experience with or knowledge of snatch blocks I couldn't have explained why. It seemed like it weighing more just made sense and know I know why.
Now if my physics professor explained it like this I would have excelled that semester! Great video, thanks for posting.
Thank you. Great setup and demonstration.
This is a great help. The pulley must be connected to the moveable load, not the anchor point (for a single pulley). I would of had this wrong. Thanks
It doesn't *have to* be if all you want is change of direction. It must be if you want mechanical advantage.
Great video demonstration.
Very informative from this I realize I could have done a recent job of clearing a fallen tree in a better way I used the snatch block only to change the direction of the pull, thanks.
very good demonstration
Ok totally cool . Here's a few things to know also . When doubling your pulling ability with a snatched block you are effectively slowing your total time moving the load by half . But that's OK cause it even safer that way. Also you can add more snatch blocks to gain even more pulling or lifting effort but the more you add the slower it Will move the load .there's a demonstration somewhere on TH-cam of a guy who added many snatchblocks to see if he could pull a tree stump by hand and it was very slow but effective.
good job sir...
Wow really good information
Thank you
Hello sir how can I join on-line lifting and rigging course
I had no idea a loads weight doubled. One being gravity and the other being load weight
Girls big friends are sometimes snatch blocks
the only thing that makes this a "snatch" block is the fact that you can open it up to allow you to put the line on it rather than having to thread it through from the end of the line. In all other respects it's a regular pulley, and all regular pulleys will act as your "snatch" block acts.
What would the scale read if the scale was placed between the weight of Subject of 120lbs and the hook of the bottom pulleys in the second example setup? .... I have not measured it myself and I plan to do the research myself and prove it ..... there are a lot of idiots playing with youtube audiences nowadays thus I never take things for granted when I watch videos .... even the 911 twin towers videos are wrong as 3 highrisers or very tall buildings were "demolished" but we only see 2 airplanes .... thanks for sharing your video and for allowing comments.
