REVIEW of the Petzl TWIN RELEASE pulley for mechanical advantage with built in progress capture
Рет қаралды 6,261
2 ай бұрынWe review the 'TWIN RELEASE' from Petzl. This is a twin sheave pulley designed to be part of a mechanical advantage system, but it has some amazing extra features when compared with you typical twin sheave pulley.
We run through all the features of this product and how to use it.
We also give you some great bonus info at the end of the video about 4:1 & 5:1 Mechanical advantages.

Excellent review, to the point. However, how often do you put such a system into work... Did you make a video about that? Thak you 🙏

Most often it is when we pull over trees, tension sidelines, or occasionally need to raise logs we are rigging.

Do you ever use it as a main Rigging line?

So, with a WLL of 2.8kn, at 5:1 you will have 3,150 lbs of command force? 4:1 - 2,520 lbs? ...or am I mistaken, and max WLL load is only 616 lbs??

The working load limit for the device as a whole is listed as 280kg. It makes sense for a block & tackle system of this size that it is only designed to raise, pull what one person can pull. Raising a 230kg load for example would be very substantial

It’s pretty simple, just great design with features to make progress capture more simple that all other twin sheave pulleys
