GM CLIMBING Swing Cheek Micro Pulley 30kN CE UIAA Certified

I use these in my tower climbing work.

I bought two of these along with a GM Climbing double rescue pulley. I am not using them for climbing, I purchased them to use to create a mechanical advantage for the winch on my ATV and other applications. I understand that it is not designed for this and will of course take necessary precautions. I have some snatch blocks for my synthetic winch rope, but they will not fit more than 1/4" rope, and the winch rope is only 50'. I have an old 150' rappelling rope that is in excellent condition, although I don't think that rappelling with it is a good idea due to its age. I have tested the mechanical advantage using these pulleys and pulling my ATV by hand up a slight incline and everything works as expected (according to a video on YouTube I am getting a 9:1 mechanical advantage using 4 pulleys). The 12mm rappelling rope runs freely and smoothly through these pulleys and they seem to be very well made. Based on the rated specs, the rope should break before the pulleys. I have a similar brand name micro pulley that I bought about 20 years ago at a climbing specialty retailer for more than $50, and the GM Climbing pulley appears to be of equal or better quality. Would I trust my life to this pulley in a climbing/rescue scenario? Based on what I have seen so far, I would have to say yes. We'll see how well they hold up for my application. For the price I won't cry if I break one and have to replace it.

I use mine for prusik tender. works great great product for the money.

The description states "Blue-Ball bearing: less contact area with axle, more efficient with very little friction in system, excellent for high speed use." BUT, there is way more play between the sheave and the axle than I would expect from ball bearings. There is no way to tell other than destructive investigation. Maybe the tolerances are loose, but for what purpose? With the axle clamped on the ends in a mini vise, I can wobble the sheave on the axle 1mm measured at the rimI gave it two stars because they do roll easily. I'm concerned about the longevity and with so much play keeping dirt and grit out.I have a number of items from GM Climbing and this is the first item I am disappointed with.

I received the pulley on time and in good working order. However, I only gave it four stars because I have not had the chance to use it yet. So I'm not sure how it will actually perform. I wanted a pulley for my BOB and this pulley is small enough and rated high enough to fulfill most tasks that I may encounter.

I loved this 30 KN swing cheek Micro GM climbing pulley; the same day i got it i stated using it after series of hauling some heavy cement bags 100 at 94 lbs per bag people were surprised that such a small device could do so much work without buckling under constant weight: this is a very strong piece of equipment i recommend it to any one for hauling.Thank yousend me news letters on new products or sales ( promotions)

Great price and a nice little pulley. I haven't used it for any climbing yet but I have used it to hoist lumber and other things while making a tree house with a tall rock climbing wall. It feels a little loose when not hooked up but works wonderfully. I have had no problems with it and may buy some more to make some force multiplier setups for hoisting heavier objects.

This is the pulley I needed for SRT setup. I got the standard GM pullets before, but those get in the way of my ascender.My standard setup had been an SMC pulley i got from REI, but this one is smaller more compact and gets the same job done.Other pulleys have gotten re-cycled into hauling systems :)

No record of GM 30kn pulley on UIAA certificate register. Feels very flimsy. Some GM Climbing stuff does have UIAA certs but not this! Wouldnt trust this within any rope system so returned as not fit for purpose.

Looks good and well made . bought it for my son for work . Not tried yet...seems good

Does as it should, holds up to heavy work.

Strong and robust construction

Excellent product and seems highly durable....
