Block and Tackle Pulley System for Lifting Objects - SoB 4000LB Breaking Strength with 65 Feet of 3/8" Rope - 7:1 Lifting Power - Heavy Duty Rope Hoist Pulley System for Garage Warehouse Construction

I got this to lift a/c units up into a ceiling. Light lifts and short distances. Worked like a charm. Runs smooth. Didn't tangle. I used a cleat to hold the rope while I was working. Will it lift 4000 lbs? Maybe, but not without a winch to pull the rope. What could I hook it to that will hold 2 tons plus a safety factory of 2? Dragging something I might give a try. That brings me to why I replaced the rope. For the price I would buy again. A 3/8" twisted nylon rope is plenty strong but nylon stretches a lot. If I have 4000 lbs of tension on it what I've made is a giant slingshot. If something breaks there will be parts flying about. I put a 3/8" by 100' Dacron climbing rope on it. The Dacron rope doesn't stretch and recoil the way nylon does and I got some more lift length. The rope did cost as much as the pulley system but safety first.

I use the Heavy duty hoist for lifting stuff in our garage up & down from a shelf I built years ago. Works slow but great - well made. It suited my application ok. Fred B.

I use this to lift my Zodiac up on to the swim platform of my yacht

I got this to replace a 2-pulley system which I’d used to raise and lower a 350 lb. foldable utility trailer. When using the 2-pulley system , I was fraught with anxiety due to how very hard I had to pull to get the trailer raised. This 4-pulley system allows me to much more easily raise and lower the trailer, reducing both the physical and mental stress on me. The issue of the rope twisting was easily remedied by taking my time running it through my gloved hands a number of times, until it stopped untwisting. I did this with the block & tackle mounted at the ceiling, with the two blocks up against one another. It will now hang with the lower block pulled all the way down without twisting, unlike before I untwisted the rope. Hope this helps.

If you base your expectation on the price you paying for this item you'll probably be satisfied. If you REALLY think you're buying a "Heavy-Duty" hoist that you can use to lift 2 tons ....... you're going to be sorely disappointed. I replaced the rope that came with it with a 3/8" rope purchased on Amazon. I did this based on other reviews indicating that the included rope was low quality and prone to twist up. I didn't try to use it with the supplied rope but did make use of the supplied rope to rig to the load I was lifting (a rooftop A/C for my travel trailer). To make sure I had adequate length of hoist rope for the lift distance I needed to make, I only strung it with 4 parts of line for the pictured lift. A/C weighed maybe 70-80 pounds I'd guess. The hoist made it easy enough to lift it up to the needed height and tie-off so that I could back my travel trailer under the load. Gradually lowered it down on top of TT.... Good to go! With the hoist fully strung over all pulleys I'd probably be OK pulling up about 1000 lbs if I had someone else to help me with the rope. Keep the math in mind here..... with all pulleys engaged this hoist is a 7:1 mechanical advantage. So to truly pull 4K with it you would have to pull on the end of the rope with 4,000/7=571 lbs. And that's not even factoring in pulley friction.
