VEVOR Twin Sheave Block and Tackle 1/2" x 100Ft Twin Sheave Block with Braid Rope 30-35KN 6600-7705LBS Double Pulley Rigging

Having bought this before the tariffs knocked the price out of my range, I have to say that, for the price I paid, the quality is pretty darned good. Smooth aluminum and well-machined rollers on decent bearings mean that there shouldn't be any snagging or shredding of the rope from sharp edges, rough surfaces and snatchy bearings.I'm using it for rolling timbers onto a timber mill, and for (eventually) erecting a timber-frame house, so I'm counting on this thing lasting a while. So far, so good.

As I recall the item description on Amazon shows the block on a human palm. It must be a giant! It covers from my wrist to the middle of my fingers, I'd guess 6"?Okay, other than it takes up more space than I planned, it's beautiful. No sharp edges, great finish. Blocks turn easily. Not too heavy. It's marked 32 Kn, which I'm assuming is kiloneutons.That translates to 7200 pounds. Yikes! You could lower a truck off a building! I'm pulling my 200# trike into my truck! Massive overkill, but I liked the design.It also includes 100' of it appears 1/2" poly rope. It's factory wound so it will take some time to get the kinks out.Nothing in this setup is wimpy.UPDATE: I'm not returning it but I'm bummed that the price dropped $10 the day after I received mine.

From initial inspection this rope and pulley system seems to be good quality, but I haven't actually used it yet.

lifts 200lb with ease

This pulley lift works great and saved me a lot of time and trouble. I needed a way to get an entire rear axle assembly out of my truck, and also load the old axle to bring it to the scrap yard. This worked perfectly for me, it easily lifted the axle and I was able to hold the lift rope with one hand while I placed the jack stands to support the load.Only thing that would make it better would be a brake to hold the load for you, but still for what I paid this thing is fantastic!

I'm no climber. Halfway up a ladder is about my upper limit. I do work with heavy stuff on occasion though and when my chain hoist is too big for the job a four part block and tackle fits the bill. I feel comfortable dealing with up to around 400 to 500 pounds with a rig like this. I bought this one to replace an ancient rig that was handed down to me and was getting a bit too rickety for comfort. I was surprised to find that you just can't seem to find a good four part block and tackle anymore. Everybody wants to sell you a poorly made six part and these are just plain dumb. They are useless for lighter loads and for heavier stuff just get a chain hoist. It's safer and much more practical. Six part rigs are prone to tangle and jam up when lowering and require a ridiculous amount of rope.These climbing style rigs seem to be all you can get that's of decent quality now. You need either low friction bearing sheaves or large diameter sheaves (4" or more) for easy lifting and smooth action, especially on the way down. Large diameter sheaves make for a heavy, bulky rig and it seems ball bearing sheaves or delrin antifriction bushings are now only available on these climbing rigs at anything like a reasonable price. These use the delrin bushings which are remarkably low in friction and don't need lubrication.Quality seems pretty good. The rope is pretty flexible, seems free of any twisting tendency under load, and grips pretty well in the hands. The action is smooth and very low friction. Frame is nicely formed from anodized aluminum with smoothly rounded edges so it won't fray the rope. Everything is clearly up to handling the practical limit of 500 pounds.Of course this rig is made for climbing not lifting or pulling things so it needs some accessories. I've found a couple of large chain quick links serve as good substitutes for the usual hooks. They're slow to use though, so getting a clevis pin style hook or two might make sense is you're using the thing more than occasionally.Used this rig to lift and position two 350 pound precast concrete cistern covers today. Held the load with one hand, positioned with the other. Easy as pie!

We use it in line work

The rope is very stiff and difficult to run through system and through 8 plate. Using it for utility purposes and can at least accomplish the goal
