Lixada Zipline Pulley 30KN Trolley Rescue for 1/4 5/16 3/8 1/2 Cable Backyard Zipline, Hauling, Rigging and Commercial Purposes,Holds Upto 6700lbs

This pulley is so much better than the one I had before, I actually had to install a foam cushion at the end to keep some of the fast (heavier) riders from hitting the pole. We love it.

Works very good, needed to make zip line shallower than it is

I misplaced my previous trolley when I put it away for the winter. Saw this one on Amazon. It arrived quickly and just as described. I use a locking carabiner and attach a number of different types of rides depending on the rider. I have a hammock chair with a seatbelt, a kid's swing with over the shoulder security, and a tire swing for older children and adults. The trolley rides smoothly on my 1/4" cable that goes between a walnut tree and a cherry tree. For braking, I've installed 4 - 36" compression springs at the bottom, so the trolley can't get to the end. It makes for a fun and popular backyard.

Build quality is great, rollers are really smooth. I'm using thus product for a dog runner for a energetic 120 pound dog that likes to pull alot. Time will tell how it holds up, I hope it will last at least 6 months.

The Zipline Pulley seems of good quality with rugged construction and smooth operation for it’s size and weight.
