Ronstan is a renowned pulley manufacturer that offers quality of all its components. They pulleys offer very little friction and high loads.
We use these pulleys to offer a very low friction Pulley Block system at an affordable price, just like many big circus companies.
This kit gives you a 3:1 force ratio, meaning that with 80 Kg you can lift 240 Kg. It's designed to offer full height capabilities on our 24' Tripods model.
Note that even if the system recommended working load is 882 Lb, it is more than the tripod -- even if the tripod is approved for 1100 Lb Working Load Why ? - Because if you use a pulley block, that means you will be using a pulley on the top hanging point. If you use a pulley, you double the load on the hanging point. Meaning that if you put 882 Lb on the Rope, you're putting over 1600 Lb of the top hanging point.
This pulley block system is plenty strong for the tripod. All this data is well explained on the Tripod's user manual.
