Video Transcript for Superwinch Electric Winch SW7750A Review

Today, we're going to take a look at the Superwinch heavy duty winch pulley block, number SW7750A. This pulley block has a capacity of 20,000 pounds. It has many uses with electric winches. It can be used to move an anchor point, keeping the winch wire coming straight out of the winch. When used correctly, a pulley block can double the pulling capacity of a winch. You can see here the cable, winch cable, will go around this wheel.Then you can put a tow strap in there and attach that to an anchor point and then the winch will do its job.

Its going across the wheel here. This fits Superwinch models with 5/16- to 3/8-of-an-inch-thick wire rope and husky winches. It also works with Superwinch hydraulic models, H8P and H10P, both the standard and CE versions of those as well as the H9W standard version of that.Taking a look at some specs here, the overall length, when it's completely folded out, is 12 inches. The wheel is four inches in diameter, the wheel opening has a diameter of an inch and a half, and both of the openings here are two inches. Finally, as a word of caution, this item is not meant to be used as a hoist, so be sure to keep that in mind when utilizing this.

That should about do it for our Superwinch heavy duty winch pulley block, number SW7750A.
