NewDoarCE Certified 25/28KN Tandem Double Speed Pulley/Trolley for Climbing, Rescue Lifting

I haven't had a chance to use this product yet but it seems to be of good quality, I'm using it to create a Polley system tho, so more of a special use-case I guess. I like how it looks and seems to be adequate for my needs

Rolls very smoothly.

It worked as it should. even with months out in the weather it has performed flawlessly and keeps the kids busy gliding through the backyard.

Tried other trolleys first than did not roll well. This one flew down the zipline with ease. My kids love it.

I guess we hoped to use this for our zip-line. It's not a ball bearing based trolley. It does not run super fast with weight on it. It works, just not the way we need it to.

Beware DONOT buy the ALUMINIUM WHEEL pully for steel cable ZIPLINEthe cable will eat or burr the pully wheels. For some reason the Q&A and marketing description makes it seem that the lighter aluminum pully is ok for zip line usage it is NOT.ONLY use ALUMINUM on rope i.e non steel cable.

light weight, smooth rolling. just wanted to add to my pullies and ropes.

Using these to replace a much heavier model pulley on flying trapeze Rig. I have done light testing and so far so good.They need to to be packed & shipped properly in a box , not a padded envelope. The first two were damaged but they replaced them very quickly.

Refait 4 fois la même tyrolienne en restant bloqué au milieu alors que les autres arrivaient à fond dans les matelas ... produit renvoyé

Non ancora peovato spero vada bene
