1. Allows to construct mechanical advantage systems used in rope access and high angle rescue. - Deviation simulator. - Y-hang simulator. - Tyrolean simulation.
2. Rope access and high angle rescue reference book and visual materials. - Mechanical advantage systems builder.
3. Allows to estimate acting forces depending on the rope sag and load.
1. I bought the pro version a while back 2yrs.The app is nice, but the builder can't do complex systems, only simple and compound.
2. Unfortunately complex systems don't seem to be able to be made (i.e. have a separate rope pulling part of the system).Overall this is a good app.
3. However the list of devices to choose from in the mechanical advantage systems builder are only the Petzl ID.
4. It's okay, I was buying it so I could experiment with the complex systems builder, a lot like the complex systems in the manual section.
5. Calculates mechanical advantage and friction forces with predefined pulleys but doesn't calculate elastic loss.
6. Also it doesn't allow to create strange systems, but only typical pulley systems.
7. I work on a ID however have a sparrow for rescue as it has a much lower friction ration to the ID.
8. Would also like to see some other devices thrown in just for fun as well.Very intuitive UI, easy to use.
9. In exchange it's so easy to use.Could be updated at some point to reflect the times and new gear.
